. Tulips at LongwoodThis color combination is magnificent for spring.

.

During 2012 to 2013, I have been visiting Longwood Gardens in Kennett Square, Pennsylvania, U.S., every few months and highlighting some aspect of this amazing place (last year I focused on Chanticleer).  Links to my previous four posts are at the end.  There is much to see there with 325 acres open to the public and 20 outdoor gardens. 

On April 18, Michael and I headed out to Longwood with the specific objective of photographing the plants in the native woodland, Peirce’s Woods.  Of course, on the way to the woods, we got sidetracked by the bulb displays out front and along the Flower Garden Walk.  Although masses of tulips and other bulbs are just about polar opposite to native plants naturalized in a woodland, they are still gorgeous so I will show you a few photos as I explain the history of the woodland.

.

Leucojum aestivumSummer snowflake, Leucojum aestivum, is a great plant for massing.  Mine grow and self-sow quite readily in both south-facing and east-facing locations as well as in full deciduous shade in my woodland.

In 1700, a Quaker family named Peirce purchased the area that is now Peirce’s Woods from William Penn to establish a working farm.  In 1798, the Peirces began planting trees to establish an arboretum on the property.  Eventually the area became known as one of the finest collections of trees in the country.  The great industrialist Pierre DuPont (1870 to 1954) purchased the property in 1906 with the specific purpose of preserving the magnificent trees.

.

container at LongwoodYou will find fabulous container gardens throughout Longwood, including this one outside the Visitor’s Center with a large native dogwood underplanted with daffodils.

Peirce’s Woods comprises seven acres planted to showcase the ornamental characteristics of native plants from the eastern U.S. deciduous forest.  The shade trees  are mostly oak, ash, maple, and tulip trees, some over 200 years old.  The understory is native flowering trees and shrubs underplanted with native groundcovers.  All the plants are labeled so it is a great place to visit to get ideas for your own woodland garden.  Before I highlight the plants there, a few more bulb photos:

Tulipa 'Rococo'I think this tulip should be called the Little Shop of Horrors tulip—you definitely would not want to stick your finger inside of it.

Flower Garden Walk at LongwoodAs we neared the end of the Flower Garden Walk, we were greeted by this magnificent vista.

We came to Longwood with the objective of viewing and photographing Peirce’s Woods.  I fully intended to show scenes of the woods as a whole and close ups of individual native wildflowers.  However, I didn’t realize that because the weather has been so cold this spring, many of the flowers would not be blooming yet.  My own garden is always ahead because it is on a south-facing slope and the soil warms up early.  Also, as soon as we got there and typical for this spring, the sun went in, the wind picked up, it started to rain, and the temperature plummeted.

.

Matteuchia pennsylvanica The only other landscape shot that I got: ostrich ferns by the shore of the lake.  These ferns can be quite tall, 3 to 5′, spread aggressively by runners, and are the source of edible fiddleheads.

Michael and I were both under-dressed with no raincoats so I decided to take photos of the plants that were blooming and come back the following week for the landscape shots and later-blooming plants.  As usual, work at the nursery got in the way, but I wanted to show you the beautiful native plants that I was able to capture on film.  Just picture me kneeling patiently by each plant and snapping the photo in between gusts of wind and bouts of rain:

.

Heuchera villosa 'Miracle' ‘Miracle’ coralbells, Heuchera villosa, is one of my favorite cultivars of this tough eastern native.  The only coralbells I sell at my nursery are offspring of eastern natives H. villosa and H. americana because I find the other types not hardy.

.

Anemonella thalictroides Rue-anemone, Anemonella thalictroides, is so delicate looking but  thrives and self-sows in dry shade.

.

Trillium grandiflorum‘Quicksilver’ large-flowered trillium, T. grandiflorum, was selected as a rapidly multiplying form of the species by Dr. Richard Lighty, at the Mt. Cuba Center in Delaware.

Caulophyllum thalictroides, blue cohoshBlue cohosh, Caulophyllum thalictroides, has these unprepossessing flowers in the spring followed by bright blue berries.  I love its leaf and stem structure and elegant overall habit.

.

Mertensia virginicaVirginia bluebells, Mertensia virginica, were everywhere just like they are in my own garden where they seed prolifically.

.

Enemion biternatum, eastern false rue-anemoneEastern false rue-anemone, Enemion biternatum, is a new plant to me.  I am going to look for it though because its flowers were lovely perched on reddish stems and it evidently spreads to make an eye-catching patch.

.

.

Erythronium americanum, adder's tongueAdder’s tongue or what I call trout lily, Erythronium americanum, usually produces hundreds of leaves and a few flowers in my garden, but this year it is blooming well everywhere.

.

Polstichum acrostichoidesThe emerging fronds of Christmas fern, Polystichum acrostichoides, look like fairies should be dancing among them.

.

Onoclea sensibilisSensitive fern, Onoclea sensibilis, is a great native fern that is underused in gardens.

Onoclea sensibilisSensitive fern looks great in a mass planting.

Claytonia virginica, spring-beautyThe wind was roaring when I tried to photograph these spring-beauties, Claytonia virginica, so they are out of focus, but I didn’t want you to miss them.

.

Claytonia virginicaSpring-beauty really has an amazing flower even when blurry.

.

Hydrophyllum macrophyllum, large-leaf waterleafLarge -leaf waterleaf, Hydrophyllum macrophyllum, has very pretty foliage.

.

Cardamine concatenata, cutleaf toothwortCutleaf toothwort, Cardamine concatenata, is a spring ephemeral that naturalizes slowly to form a colony in the shade.

.

Uvularia grandifloraLarge-flowered bellwort, Uvularia grandiflora, is one of my favorites.  It grows 1 to 2 feet tall, has unusual and elegant yellow flowers, and grows in full, dry shade.  I don’t know why this plant isn’t more popular, but it doesn’t sell well at my nursery even though I have big stands of it in my display gardens.

All the plants profiled are native to Pennsylvania and the East Coast.  If you would like to see if a plant is native to your state, the best place to look is the USDA Natural Resources Conservation Service Plants Database.  All you do is put in the name of the plant and you will be shown a map of where it is native in the U.S.  I also have all these plants in my garden except toothwort and false meadow-rue, and I highly recommend them.

European Wood Anemone, My Collection

. Anemone nemorosa 'Vestal'European wood anemone ‘Vestal’, Anemone nemorosa

.

My last post highlighting my epimedium collection was very popular.  It set a new record for views in a single day.  It was also quite helpful in allowing me to document the collection in photographs.  That has inspired me to do a similar post introducing another relatively obscure group of plants blooming right now, European wood anemones or Anemone nemorosa.  I first saw them in Charles Cresson’s garden in 1995, and he gave me five cultivars to take home.  I have since increased that number to 13 (15 if you count the two that died).  I want to share this special plant with you and discuss its culture and garden uses.

.

Anemone nemorosa 'Vestal'‘Vestal’ is a moderate spreader.

European wood anemone is what is often called a bulb ally.  It springs from skinny, stick-like rhizomes that spread through  leaf litter to form patches of beautiful flowers and leaves.  You can buy the dried rhizomes in the fall like other bulbs or you can buy growing plants in the spring from Carolyn’s Shade Gardens or other specialty nurseries.  Wood anemones grow in part to full shade and like woodland soil with lots of organic matter. I have never watered them, but I do mulch them with a covering of ground leaves in the fall.  The various cultivars spread at different rates in my woods from slow to fast.  I will indicate what type of spreader each one is in my garden, but it may depend entirely on my conditions and where each variety is planted

.

A. nemorosa 'Robinsoniana'‘Robinsoniana’ is a gorgeous blue but a slow grower in my garden.

European wood anemones are a spring ephemeral.  They take advantage of the sunlight before the woody plants leaf out and then go dormant when it gets hot and shade prevails.  Although they disappear, they are still a good groundcover because the rhizomes are so thickly matted that no weeds can grow.  Just plant later emerging plants like ferns or hostas around them if the hole will bother you after they disappear.

.

Anemone nemorosa 'Leeds Variety'‘Leed’s Variety’ spreads moderately.

.

Anemone nemorosa 'Leed's Variety'‘Leed’s Variety’ has the biggest flowers, about 2″ wide, of any of my cultivars.

.

European wood anemones bloom in the mid-Atlantic for the whole month of April and sometimes into May, depending on the weather.  Their plentiful flowers are 1 to 2″ wide and generally white, blue, and pink and can be double or semi-double.  Many of the cultivars are very similar in appearance.  The Royal Horticultural Society’s plant finder lists almost 100 varieties.  There are some closely related yellow-flowered forms as well as some weird green-flowered varieties, ‘Virescens’ and ‘Green Fingers’, both of which I have killed.  Wood anemones’ leaves are an attractive dark green with three deeply incised segments.  They form compact mounds about 6 to 8″ tall.

.
Anemone nemorosa 'Wyatt's Pink'‘Wyatt’s Pink‘ is a moderate grower.

.

Anemone nemorosa 'Wyatt's Pink'‘Wyatt’s Pink’

.

A patch of wood anemones really lights up a woodland opening, and I like to let mine develop as big a swathe as they can manage.  They are native to the woodlands and shady banks of western Asia and the northern temperate zones of central Europe, including England where many cultivars have been selected.  According to the RHS, they are hardy to zone 5 and another source says zones 5 to 9, but you should do your own research before planting them if you are not in the mid-Atlantic.

.

Anemone nemorosa 'Bractiata'‘Bracteata’ is a fast grower.

.

Anemone nemorosa 'Bractiata'‘Bracteata’ is an unusual and very elegant form with the white flower color extending into the leafy bracts.

.

European wood anemones are quite easy to grow and well worth adding to your garden if you can find them.  Here are some of my other cultivars:

.

Anemone ranunculoidesYellow wood anemone, A. ranunculoides, is closely related to A. nemorosa.  It is the first to come into bloom and spreads quickly but not aggressively, even self-sowing.

.

Anemone ranunculoidesYellow wood anemone

.

Anemone nemorosa 'Lychette' ‘Lychette’ is a moderate spreader.

.

Anemone nemorosa 'Allenii' ‘Allenii’ is similar to ‘Robinsoniana’ but more silvery blue in color.  It is a moderate spreader.

.

Anemone nemorosa 'Alba' ‘Alba’ spreads slowly for me.

.

Anemone nemorosa pink formI acquired this Anemone nemorosa from the old Heronswood Nursery in Washington with the name “pink form”.  It is a moderate grower.

.

Anemone nemorosa 'Alba Plena'‘Alba Plena’ is very similar to ‘Vestal’ but it is a faster spreader.

.

Anemone nemorosa 'Alba Plena'‘Alba Plena’

.

Anemone x seemaniiAnemone x seemanii is a cross between A. ranunculoides and A. nemorosa, producing this lovely pale yellow flower.  It is a moderate grower.

.

.

Anemone nemorosa 'Blue Eye'I will end the profiles of my cultivars with this photo of the absolutely exquisite ‘Blue Eyes’, which I also got from Heronswood.

.

Most of the plants in my woodland are allowed to form large patches for a natural look, and European wood anemone fits right in.  Here are some photos of how I use it:

.

European wood anemones are for sale at Carolyn’s Shade Gardens.  If you are not local or you want some of the really special cultivars,  you can order them from Arrowhead Alpines in Michigan, a great mail order nursery for unusual woodland plants.

Epimediums, My Collection

Posted in evergreen, groundcover, Shade Gardening, Shade Perennials with tags , , , , , , , , , , , , , , , , , , , , , , , , , on April 18, 2013 by Carolyn @ Carolyns Shade Gardens

The 2013 Miniature Hosta Mail Order Catalogue, containing choice selections of miniatures for shipping all over the US, is now on my right sidebar here, and we are ready to ship.

. Epimedium pinnatum subsp. colchicumEpimedium pinnatum subsp. colchicum, evergreen.

.

Nan Ondra at the fabulous blog Hayfield recently praised my blog saying: “If you want to see how beautiful a spring garden can look here in southeastern Pennsylvania, I highly recommend popping over to Carolyn Walker’s blog, Carolyn’s Shade Gardens. It’s where I go when I need a good dose of primroses, spring phlox, and other early-blooming beauties.”   A lot of Nan’s readers took her advice and visited my blog.  I have been trying to think of what I could do to thank Nan, not just for the recommendation, but for her advice when I started my blog and numerous consultations on selling my photos.  I decided that if she needs a dose of spring flowers, then epimediums are what she should have.  Nan, this post is for you!

.

Epimedium x rubrumEpimedium x rubrum spreads at a moderate pace and can be used as a groundcover, leaves flushed red in the spring.

I try not to let myself collect too many types of plants because it can interfere with good garden design.  But epimediums, also known as barrenwort, bishop’s hat, fairy wings, horny goat weed, and rowdy lamb herb, are a plant I love so much that I collect them.  According to my records, I have almost 30 varieties.  That might seem like a lot, but there are actually hundreds of types of epimediums.

.

Epimedium x versicolor 'Sulphureum'Epimedium x versicolor ‘Sulphureum’ is the fastest spreading epimedium I have and makes an excellent groundcover, semi-evergreen.

Epimediums are native to Asia, Europe, and North Africa.  They are long-lived and easy to grow in part to full shade and are a great plant for dry shade.  Some of the more available varieties like ‘Sulphureum’, E. x rubrum, E. x warleyense, and ‘Frohnleiten’ spread readily but not quickly to form an attractive groundcover.  I grow mine all over my garden but mostly as specimens on the steep hill  in back between all my hostas (yes, I collect those too).  Their flowers are small but quite beautiful, elegant, and abundant.  Epimediums are a plant that needs to be viewed close up.  This time of year I walk around mesmerized by their beauty.

.

Epimedium cantabrigienseEpimedium x cantabrigiense, semi-evergreen.

Epimediums bloom in April and May, and their flowers are breathtaking as you can see from the photos.  However, their leaves are just as beautiful with their elegant, unusual shapes.  They often come out flushed with bright colors in the spring, and many varieties have great fall color too.  Some are semi-evergreen to evergreen.  Epimediums range in height from 8 to 16″.

.
Epimedium pubigerumEpimedium pubigerum, semi-evergreen.

Epimediums are perfectly suited to our mid-Atlantic climate, especially our new hotter, drier, drought prone climate.  A quick survey of the epimediums listed in the Missouri Botanical Garden Plant Finder indicates that they are hardy from zones 4 or 5 to 8 or 9, but you should do your own research if you are not in the mid-Atlantic.  I usually choose a well-drained location because like hellebores they don’t tolerate poor drainage, and add compost at planting.  They are great under shallow-rooted trees and are deer resistant.

.

Epimedium x warleyenseEpimedium x warleyense, spreading, from Miss Wilmott’s garden Warley Place, England, evergreen.

I sell up to 10 different types of epimediums at Carolyn’s Shade Gardens depending on the year.  There are seven for sale right now and now is the best time to view them in my garden.  But if you get hooked, then you need to know about Garden Vision Epimediums in Templeton, Massachusetts, 978-249-3863, epimediums@earhtlink.net.  Their catalogue lists at least a 150 epimediums and is encyclopedic with comprehensive descriptions and color photos plus zone information for each variety.  A visit to their Open Nursery Weekends, this year May 3 to 5 and 10 to 12, from 10 am to 4 pm, is a magical experience.

.

Epimedium x perralchicum 'Frohnleiten'Epimedium x perralchicum ‘Frohnleiten’, tough and shiny evergreen leaves.

All the photos in this post were taken in my garden today.  I hope that you too will come to love this wonderful genus:

.

Epimdium x versicolor 'Cupreum'Epimedium x versicolor ‘Cupreum, look at those gorgeous leaves, semi-evergreen.

.

Epimedium x 'Kaguyahime'Epimedium x ‘Kaguyahime’, probably my favorite epimedium for its lovely two-tone purple flowers and dagger-like, purple-mottled leaves, evergreen.

.

Epimedium grandiflorum 'Yubae'Epimedium grandiflorum ‘Yubae’, produces a second flush of leaves and flowers.

.

.

Epimedium grandiflorum 'Tama No Genpei'Epimedium grandiflorum ‘Tama No Genpei’, I love this one too, re-blooming.

.

.

Epimedium alpinum 'Shrimp Girl'Epimedium alpinum ‘Shrimp Girl’, I love the name and the coral-orange color on this diminutive but spreading cultivar, semi-evergreen.

.

Epimedium x warleyense 'Orange Queen'Epimedium x warleyense ‘Orange Queen’, evergreen, here with Pulmonaria ‘Benediction’.

Here are some shots of mature patches of epimediums so you can get an idea of what they look like in the landscape:

.

Seven varieties of epimediums will be for sale at Carolyn’s Shade Gardens’ open hours this weekend: Friday, April 19, 10 am to 4 pm, and Saturday, April 20, from 10 am to 2 pm.  If you are not local or you want some of the really special cultivars,  you can order them from Garden Vision Epimediums.

Primroses That Live

Posted in Shade Gardening, Shade Perennials with tags , , , , , , , , , , , , , , , , , , , , on April 10, 2013 by Carolyn @ Carolyns Shade Gardens

Primula 'Belarina Nectarine'‘Belarina Nectarine’ double primrose

.

This weekend Carolyn’s Shade Gardens is holding its second open house sale of the season, and one of the featured plants is primroses.  Primroses are a hard sell to gardeners because, as my customers always tell me, they’ve tried primroses and they don’t come back.  I usually begin my defense of the hardiness of primroses by asking if they bought the brightly colored varieties often sold in supermarkets and other big box type stores in early spring.  We have all done it, who can resist?  Unfortunately, those primroses are not suited to our climate and really shouldn’t be marketed as perennials.  There are, however, many lovely primroses that come back every year.  Here are just a few:

.

Primula verisCowslip primroses are very easily grown in part shade and average soil without supplemental watering.  They produce a 6 to 12″ stem topped by nodding, fragrant, lemon-yellow flowers in midspring.

.

Ipheion uniflorum, Primula veris, Brunnera macrophylla at Carolyn's Shade GardensCowslip primrose, Primula veris, with spring starflower and perennial forget-me-not.

.

Primula x polyantha 'Old Brick Reds', Corydalis cheilanthifloia at Carolyn's Shade GardensEnglish primrose ‘Old Brick Reds’, P. x polyantha, is very easy to grow in average soil and part shade, multiplying rapidly.  The scarlet red flowers with a yellow eye can appear as early as the end of March and last into May.  The rosette of wintergreen leaves is bright green. ‘Old Brick Reds’ is a 17th century heirloom primrose given to me by one of my classmates at the Barnes Arboretum.  Paired here with fern-leafed corydalis, C. cheilanthifolia.

.
Primula kisoanaPrimula kisoana is so rare that it does not appear to have a common name, but that doesn’t mean it is hard to grow.  It spreads by underground runners to form patches of velvety, unusually shaped leaves topped by many bright pink flowers in April and May.  It doesn’t mind dry soil and has creeped out of the amended beds where I planted it to colonize the edges of the rocks along my woodland path.

.

Primula kisoana 'Alba'Even rarer is the white-flowered form, P. kisoana ‘Alba’.

.

Primula japonicaJapanese primroses, P. japonica, come in many different shades from pure white to dark magenta held on 20″ stems and set off beautifully by their 10″ long bright green leaves.  The flowers are candelabra form which means that they bloom successively in tiers one over the other for a long period of time in May and June.  They are very easy to grow and self-sow readily as long as you plant them in a moist or wet area.  They will grow in average soil but will die as soon as you have a drought.  I am not sure where I got this photo or I would give proper credit.

.

Primula sieboldiiOne of the many forms of Japanese woodland primroses, P. sieboldii, that I have collected over the years.

Japanese woodland primroses (not to be confused with the Japanese primroses described above) are a wonderful addition to the garden because they grow in full dry shade but also thrive in average or even moist soil.  They are from Asia and have been cultivated in Japan since the 16th century but are rare in the US.  Reportedly over 500 cultivars have been named, and I see how they can become addictive because I keep adding new forms to my garden.  They bloom in April and May in colors from white to pink to purple and everything in between.  The crinkly green leaves form large patches and effectively block weeds even though they go dormant when it gets hot out.

.

Primula sieboldiiThe flowers of Japanese woodland primrose often have a different color “reverse” (back), here white with lavender pink.

.

Primula sieboldiiThey also can have filigreed edges kind of like a doily for a lovely dainty effect.

.

Primula sieboldii 'Snowflake'The earliest to bloom in my garden is pure white ‘Snowflake’.

.

Primula sieboldiiThis is the straight species and is one of my favorites.  Local readers should make an effort to see Japanese woodland primrose blooming in my garden because the photos don’t do justice to their beauty.  They are located under the tree below the birdhouse.

.

Primula 'Belarina Valentine'‘Belarina Valentine’ double primrose

Even though they look delicate, the Belarina Series of double primroses has proven to be reliably perennial in my garden.  They bloom in late April and May, and the leaves are just emerging right now.  I have sited them in an east-facing location between stepping stones under a Japanese maple.  The soil probably does not dry out because of the stones and the heavy mulch of leaves and pine needles.  If you are looking for a colorful primrose like the non-hardy grocery store varieties, these showy double primroses are just what you want.

.

Primula 'Belarina Pink Ice'‘Belarina Pink Ice’ double primrose

.

Primula 'Belarina Cobalt Blue'‘Belarina Cobalt Blue’ double primrose

.

Primula 'Belarina Nectarine'‘Belarina Nectarine’ double primrose

.

Many of these primroses will be available at the open house sale at Carolyn’s Shade Gardens this Saturday, April 13, from 10 am to 3 pm.  The rest will be for sale as they come up because I grow most of them myself.  Readers who are not local now know which reliably perennial primroses to ask for at their local nursery.

Native Plants 2013

Posted in groundcover, native plants, Shade Gardening, Shade Perennials with tags , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , on April 3, 2013 by Carolyn @ Carolyns Shade Gardens

Stylophorum diphyllum & Mertensia virginicaThis photo is one of my favorite shots of my native woodland which has huge swathes of some of the native plants that are particularly good spreaders, including Virginia bluebells, Mertensia virginica, and Celandine poppy, Stylophorum diphyllum.  For more photos of my woods and information on the natives I grow there click here.

.

This weekend Carolyn’s Shade Gardens is holding its second annual Native Wildflower Weekend on Friday from 10 am to 4 pm and Saturday from 10 am to 2 pm.  This event is my seventh annual native plant event and is timed to coincide with my native woodland coming into bloom.  However, this is the coldest spring that I have experienced since starting Carolyn’s Shade Gardens 21 years ago.  The timetable for my events is the same but the plants in the ground and in the pots are on a totally different schedule—they didn’t get the memo, they think it’s early March.

.

Polemonium reptansAnother shot of what my woods should look like with dwarf Jacob’s ladder, Polemonium reptans, in the foreground and native wild-ginger, Asarum canadense, in the background.  The Jacob’s ladder is visible right now, but the ginger has not even emerged from the mulch of ground leaves.

Normally I write a blog post around this time featuring native plants. That process usually involves heading out to the garden to take a lot of photos of my native plants to use in the article.  However, the only plants blooming right now are hellebores, pulmonarias, and many beautiful non-native bulbs—all my winter-blooming shade plants.  So I thought I would use some of my existing photos to show you what spring usually looks like and to highlight some native favorites.

.

Senecio aureusThe woodland with golden groundsel, Senecio aureus, and Virginia bluebells.  Golden grounsel is a wonderful native plant with fragrant yellow flowers and wintergreen leaves.  It spreads aggressively to form an impermeable groundcover and should only be planted in places where its habit can be accommodated.  It is a wonderful replacement for pachysandra, vinca, or ivy.

.
Phlox stolonifera 'Home Fires'‘Home Fires’ creeping phlox, P. stolonifera, is actually blooming in the pots for sale at my nursery.  You have to admire its courage!

.

Phlox stolonifera 'Sherwood Purple'‘Sherwood Purple’ creeping phlox is the best spreader for use in a shady woodland.  Creeping phlox should not be confused with moss phlox, P. subulata, which is also native but prefers part shade.

.

Heuchera villosa 'Citronelle'Lemon coral bells, Heuchera villosa ‘Citronelle’, keep their color all winter as do all the coral bells native to our area.  They are also tough as nails compared to the coral bells derived from western natives that don’t work here.

.

Heuchera 'Green Spice' Terra Nova photo‘Green Spice’ coral bells have beautifully patterned leaves all winter.

.

Spigelia marilandicaIndian pink, Spigelia marilandica, is a very flashy native that blooms in May and June and attracts hummingbirds.  It is dormant in the garden and in the pots right now.

.

Phlox divaricata 'Blue Moon'The lovely fragrant flowers of ‘Blue Moon’ wild sweet William, Phlox divaricata, are a great spreading addition to the woodland edge.

.

Phlox divaricata 'May Breeze'‘May Breeze’ wild sweet William is a steely white.

.

Lobelia cardinalisOne of my all time favorite native plants, cardinal flower, Lobelia cardinalis, blooms in the fall and is a hummingbird magnet.

.

Sanguinaria canadensisNo garden should be without bloodroot, Sanguinaria canadensis.

.

Polemonium reptansDwarf Jacob’s ladder and Celandine poppy are equally vigorous and combine well.

.

Podophyllum peltatumThe elegant leaf pattern of our native mayapple, Podophyllum peltatum, is under-appreciated.

.

Aquilegia canadensisAnother hummingbird attractor, wild columbine, Aquilegia canadensis, needs very good drainage.

.

Asarum caudatumIf you like the shiny leaf of European ginger, the native long-tailed ginger, Asarum caudatum, from the west coast is a nice alternative.  It grows faster and is less picky about siting.
.

Phlox subulata 'Purple Beauty'‘Purple Beauty’ moss phlox, P. subulata, is one of seven different colors that I will be selling this season.  Moss phlox is often seen in quite a bit of sun but it also thrives in part shade locations.  It likes to be well-drained.

.

Jeffersonia diphyllaA treasured native, twin-leaf, Jeffersonia diphylla, has not even started to emerge yet.

.

Camassia leichtlinii 'Coerulea'Another native of western US, ‘Caerulea’ camassia, C. leichtlinii, grows in the full shade of my woodland and in the sunny areas beside my lawn.

.

Erythronium 'Pagoda'‘Pagoda’ dogtooth violets, Erythronium ‘Pagoda’, are so happy in my woods that they have self-sowed all over.

.

Geranium maculatum 'Espresso'My favorite time of year for the purple-leafed native geranium ‘Espresso’, G. maculatum, is when it first emerges in the spring.

.

Tiarella cordifolia 'Brandywine'Foamflowers, Tiarella cordifolia, are a wonderful Pennsylvania native.  This is the spreading form ‘Brandywine’.

.

Iris cristataIn well-drained locations, blue dwarf crested iris, I. cristata, spreads to make large colonies.

.

Every photo in this post was taken in my garden.  If you live in the area, I hope you can visit when the plants are in bloom.  Meanwhile, if you want them in your garden, this weekend is your chance to acquire them.

2013 Winter Interest Plants

Posted in garden to visit, hellebores, Shade Gardening, snowdrops, winter, winter interest with tags , , , , , , , , , , , , , , , , , , , , , , , , , , , , on March 4, 2013 by Carolyn @ Carolyns Shade Gardens

Galanthus 'Brenda Troyle'Galanthus ‘Brenda Troyle’ is one of the most robust and fragrant snowdrops in the Cresson garden.

This may be my last post that focuses on snowdrops, and I am sure some readers will rejoice.  I am aware that many gardeners do not share (or understand) my obsession.  However, I want to show photos from the recent Winter Interest Plants Seminars hosted by Charles Cresson for my nursery customers. 

Before I get to that though, I have to tell you about the snowdrop event this weekend at Winterthur, the fabulous garden in Delaware, US.  On Saturday, March 9, at 11 am, Alan Street, the world famous snowdrop expert from Avon Bulbs in England, is presenting the annual Bank to Bend Lecture on snowdrops.  Carolyn’s Shade Gardens will be one of two nurseries selling snowdrops and other winter interest plants at Winterthur.  I hope to see you there.  Here are the details:


winterthur

Join plantsman and snowdrop expert Alan Street of the renowned nursery Avon Bulbs as he offers insight into these precious flowers, sharing how they have become a worldwide phenomenon and how Avon Bulbs brings them to market. Registration includes tours of the March Bank display and access to specialist nurseries selling snowdrops and other winter interest plants. $20 non-members; $10 members.

Call 800.448.3883 to register or find out more.

Bank to Bend includes free admission to the garden, tours of the March Bank and access to specialist nurseries Black Hog Horticulture and Carolyn’s Shade Garden to purchase rare and unusual bulbs and other winter interest plants.

.

Cresson Winter Interest SeminarCharles Cresson talks about his witch hazels, winter aconite, and snowdrops with some die hard winter interest gardeners.

This is the third year that nationally known horticulturalist Charles Cresson has hosted my customers in his Swarthmore, Pennsylvania, garden to view and discuss winter interest plants.  Every year we see different plants, depending on the weather, but every year the group is just as enthusiastic despite the weather.  This year, February (and all winter really) has been cold and dismal, and the seminar days were no exception, but the attendees were enthusiastic and full of questions for Charles.

Cresson Winter Interest SeminarsCharles demonstrates how he protects important plants with plastic boxes if the weather is going to be unseasonably cold.

Plants are “late” to come out this year because it has been so cold.  The emergence of winter interest plants like perennials and bulbs is dependent more on the soil temperature than on the date.  If the soil warms up early, as it did in 2012 when we had no winter, many plants will bloom early.  This year it has been cold and gray, and many plants have yet to bloom or emerge.  Yet, such is the magic of Charles’s garden that there was a lot to see.  Here are some of the highlights in the order in which we saw them:

Narcissus 'Rijnveld's Early Sensation'After seeing this daffodil for many years blooming in Charles’s garden in February, I finally added it to mine this year.  It is called Narcissus ‘Rijnveld’s Early Sensation’.

.

Eratnhis hyemalis (pale yellow form)A rare pale yellow form of winter aconite, Eranthus hyemalis.

.

Crocus tommasinianusThe snow crocus, C. tommasinianus, is my favorite crocus because it blooms now with the snowdrops and multiplies rapidly.

.

Crocus tommasinianus 'Ruby Giant'‘Ruby Giant’ snow crocus is a deeper purple.

.

Crocus tommasinianus 'Taplow Ruby'‘Taplow Ruby’ snow crocus

.

Galanthus 'Atkinsii'Galanthus ‘Atkinsii’ is an old-fashioned and reliable snowdrop that should be part of any collection.

.

Galanthus 'Atkinsii' & Arum italicum 'Pictum'One of my favorite combinations, ‘Atkinsii’ with Italian arum, A. italicum ‘Pictum’.

.

Helleborus x ballardiae 'Pink Frost' with Cotoneaster salicifolius 'Henryi'The leaves of ‘Pink Frost’ hellebore, H. x ballardiae ‘Pink Frost’, pair beautifully with this rare cotoneaster, C. salicifolius ‘Henryi’.

.

Helleborus foetidus & Helleborus x ballardiae 'Pink Frost'‘Pink Frost’ again with bearsfoot hellebore, H. foetidus, in another winning combination.

.

Helleborus x ericsmithii 'Winter's Song'‘Winter’s Song’ hellebore, H. x ericsmithii ‘Winter’s Song’ is very early blooming so it was fully out on this cold February day.

.

Helleborus x 'Ivory Prince'‘Ivory Prince’ hellebore was just starting to open.

.

Iris unguicularis subsp. cretensisThis subspecies is an especially dark colored version of the winter-blooming Algerian iris, Iris unguicularis subsp. cretensis.

.

Galanthus 'Mighty Atom'

Galanthus ‘Mighty Atom’ has one of the best presentations of any snowdrop.

.

Galanthus rizehensisGalanthus rizehensis is a rare and desirable snowdrop species.

.

Galanthus 'Standing Tall'Charles’s newly introduced snowdrop ‘Standing Tall’ continues to stand up to whatever the weather throws at it.  If you didn’t know better you would think it was a daffodil.

.

Galanthus elwesii 'Standing Tall' Cresson photo-001‘Standing Tall’ in full bloom in early January.

.

Galanthus 'Beth Chatto' ‘Beth Chatto’

.

Galanthus 'Godfrey Owen'Charles and I both acquired six-petaled ‘Godfrey Owen’ last year but his was not felled by snow and ice.

.

Galanthus 'Godfrey Owen'‘Godfrey Owen’

.

Galanthus 'Godfrey Owen'The inner segments of ‘Godfrey Owen’ are extraordinary too.  This photo represents to me what galanthophiles are all about.

.

I know the participants enjoyed themselves because even after an hour and a half in the cold, they were still asking Charles questions.  I hope my readers have gotten some vicarious enjoyment.

December 2012 Garden Bloggers Bloom Day

Posted in bulbs for shade, Camellias, hellebores, Shade Gardening, Shade Shrubs, winter, winter interest with tags , , , , , , , , on December 17, 2012 by Carolyn @ Carolyns Shade Gardens

DSCN8663The first of my hybrid hellebores is just about to bloom: Helleborus x ‘Snow White’ (aka ‘Snow Bunting’).

I am two days late for the official Garden Blogger’s Bloom Day.  On the fifteenth of each month garden bloggers from all over the world post photos of what’s blooming in their gardens, and their posts are collected by Carol at May Dreams Gardens.  Nevertheless, I thought it would be fun to see which plants are pretty enough to get me outside in December on a somewhat warm but dreary, rainy day.  I also wanted to add a new twist by allowing myself only one pass through the garden for photos instead of the numerous trips required by a normal post.

Not surprisingly if you read my blog, Italian arum, hellebores, snowdrops, camellias, hardy cyclamen, and coral bells are hogging the show this time of year accompanied by a few others.  Let’s see what we have:

DSCN8642 Fall-blooming camellia ‘Winter’s Snowman’ has been blooming since October and still has buds waiting to open.

My late fall garden has been immensely improved by the addition of fall-blooming hardy camellias.  All five of mine are blooming now and have plenty of buds left.  For more information on fall-bloomimg camellias, click here.

.

DSCN8650‘Lu Shan Snow’

DSCN8656‘Winter’s Darling’

Italian arum is always a highlight this time of year after its fresh foliage emerges from dormancy in early fall:

DSCN8659dwarf Italian arum ‘Tiny Tot’

.

DSCN8654‘Gold Rush’ Italian arum, my favorite

Hellebores are just about to take over as the stars of the garden for the next few months.  For more information on hellebores, click here and follow the links at the end of the post.  If it wouldn’t violate my parameter for this post, I would run out and photograph bearsfoot hellebore and ‘Praecox’ Christmas rose, which are both almost open.  As it is, I have these two hellebores for you:

DSCN8662Another shot of the first flower on ‘Snow White’.

.

DSCN8643After blooming in October, ‘Josef Lemper’ Christmas rose is at it again and will continue to bloom into spring.

.

My favorite coral bells or heucheras are the cultivars that give me 365 days of colorful foliage, some of which are pictured below.  If I could go back outside, I would add ‘Frosted Violet’ and ‘Bronze Wave’.  I would also include some photographs of pulmonarias, especially ‘Diana Clare’:

DSCN8646‘Caramel’ heuchera continues to change from one beautiful hue to the next through out the winter.

.

DSCN8652Green Spice’ is new to my garden this year and looks like a winner.

.

DSCN8653‘Citronelle’ is a customer favorite for brightening dark corners.

You know I couldn’t resist showing you a few snowdrops:

DSCN8640  ‘Potter’s Prelude’, a fall-bloomimg snowdrop cultivar, is getting to the end of its bloom period which began in mid-November.

.

DSCN8658A clump of early blooming giant snowdrops, Galanthus elwesii, hides in the Japanese holly ferns and hellebores.

Except during the heart of the summer when they are dormant, hardy cyclamen are stars in my garden.  I find their highly variable leaf patterns endlessly fascinating.  For more information on hardy cyclamen, click here.

DSCN8660The last few blooms on fall-blooming hardy cyclamen, C. hederifolium, which began blooming at the end of August.

.

DSCN8661Spring-blooming hardy cyclamen, C. coum, doesn’t need flowers to attract attention.

Here are some more late fall stars that might surprise you:

DSCN8639‘Brigadoon’ St. John’s wort always takes on this lovely peach color for the winter.

.

DSCN8644This new mahonia called ‘Soft Caress’ was given to me by the breeders at the Southern Living Plant Collection to trial in my garden.  It is evergreen, blooms now, and is hardy to zone 7.  For more information, click here.  I have high hopes for it because I have since seen it in two other local gardens.

.

DSCN8648This sedum always turns a lovely burgundy in the fall.  Unfortunately, I don’t know its exact name.

.

DSCN8651Bigroot geranium, G. macrorrhizum, takes on red and pink tones for the winter.

.

DSCN8649‘Black Scallop’ ajuga has quickly become one of my favorite groundcovers because its dark purple leaves remain shiny and beautiful through the winter.

You may be wondering why I would limit myself to one trip outside for photos for this post.  Every article that you read here takes me at least a full day to compose, including the photography, the research, the writing, and the editing.  I wanted to see if I could cut that back to a few hours and still produce a quality product, and I believe I have been largely successful.  It would only work for a post like this though where no significant supporting research was required. 

Enjoy, Carolyn

Fall-blooming Hardy Cyclamen

Posted in bulbs for shade, evergreen, Fall, Fall Color, groundcover, Shade Gardening, Shade Perennials, winter interest with tags , , , , on October 17, 2012 by Carolyn @ Carolyns Shade Gardens

Fall-blooming hardy cyclamen, C. hederifolium,  used as a groundcover under Hosta ‘Blue Angel’ 11/13/10.

My last post on hardy begonias sparked such interest and comments that I thought I would profile another unusual star performer for fall.  Like the begonia, I learned about hardy cyclamen at a course I took at Longwood Gardens in Kennett Square, PA, this one on bulbs in 1995.   And just like the begonia, I couldn’t believe that there was a plant that looked like my florist cyclamen house plant but grew outside and came back every year.  I talked about hardy cyclamen in my post on More Flowering Wintergreen Groundcovers for Shade, but I want to profile it in more detail here and include more photos.

Fall-blooming hardy cyclamen

There are several species of hardy cyclamen, but the two that are usually available are fall-blooming Cyclamen hederifolium and spring-blooming Cyclamen coum.  I have them both and love them, but if you are just starting out, the fall-blooming variety is much easier to grow.  Cyclamen coum requires the kind of excellent drainage rarely found in mid-Atlantic gardens.  I grow mine most successfully in my rock garden and also less abundantly between tree roots.

Hardy cyclamen begins to bloom in the fall before its leaves re-emerge from summer dormancy.

The life cycle of hardy cyclamen is unusual.  I guess you could say it begins in September when dozens of small pink flowers begin to bloom before the leaves emerge.  Each flower is on a separate 4 ” stem and looks just like a miniature florist cyclamen flower with gorgeous reflexed petals.  The flowers continue to be produced abundantly in succession through out the months of September and October and sometimes for parts of August and November too.  They are said to be fragrant, but I have never noticed a scent.

I would grow hardy cyclamen just for the flowers, but the leaves are spectacular.  They emerge slowly as the flowers are blooming in late September and take several weeks to reach their full size.  “Variable” is an understatement to describe their wonderful shapes, patterns, and colors.  They can be round to lance-shaped, lobed or entire, serrated or smooth edged, dark green to silver.  And the patterns on the leaves are indescribable, I will just have to show you….


Now that you have seen how gorgeous the leaves are, you will be able to truly appreciate another of their wonderful qualities: they stay green and fresh all winter!  The photos above were taken in November but I could just as easily have captured their glory in March.  Instead of going dormant in the winter like most of our plants, hardy cyclamen goes dormant for a few months during the summer.

White hardy cyclamen, C. hederifolium ‘Album’

There is a lovely white cultivar of fall-blooming hardy cyclamen called ‘Album’.  Some of mine have pure white flowers and others have white with a pink blotch.  It is just as hardy as the parent species and seeds around my garden readily.

Hardy cyclamen growing between roots at the base of  tree.

Hardy cyclamen is native to western Turkey, eastern Europe, including Albania, Bulgaria, and the Balkans, and southern Europe, including France, Italy, and Greece.  It is  a woodland plant that requires good drainage and shade.  In fact it thrives on summer drought in dry shade.  Although it likes to grow between tree roots and rocks, I have success with it in any shaded eastern facing, dry location.  As you can see from the photo below, my plants seed prolifically and eventually fill in to make a solid mat of groundcover.

Seedlings emerging in a new location across from an established patch with no help from me.  I have a feeling that ants move the seeds around.

Hardy cyclamen grows from a corm, which reportedly can reach the size of a dinner plate when old.  There are growing points all over the top of the corm.  If you try starting the plant this way, plant the corms with no more than 1″ of soil on top plus a very light mulch of leaf litter.  I have never done this because I have read many times that dried corms do not establish well and are often collected from the wild.  I started all my patches from established potted plants and that is how I sell hardy cyclamen at my nursery.  Look for it in my 2013 Snowdrop Catalogue.

The top of corms (about 2 1/2″ wide) of hardy cyclamen with the leaves starting to emerge.  The corms are spherical when younger.

The bottom of the corms—this side down.

The hardiness zone information for hardy cyclamen is inconsistent.  Some sources say USDA zones 7 to 9.  The Missouri Botanical Garden plant finder lists it for zones 5 to 9, while other sources say it grows successfully in upstate NY in zone 4.  You will just have to try it.  For all my UK readers, hardy cyclamen received an Award of Garden Merit from the Royal Horticultural Society.

Hardy Begonias for Fall Color

Posted in Fall Color, Shade Gardening, Shade Perennials with tags , , , , on October 8, 2012 by Carolyn @ Carolyns Shade Gardens

The fall-blooming flowers of hardy begonia, B. grandis.

In 1991, I took a perennial plants course at Longwood Gardens in Kennett Square, PA, and was introduced to many wonderful plants that I have since planted in my garden (hellebores being one of them).  One of the most fascinating was hardy begonia or Begonia grandis.  I just couldn’t believe that there was a plant that looked just like my angel wing begonia house plant but grew outside and came back every year.


I can’t remember where I finally located a plant, but hardy begonias soon found their way to my garden and have been multiplying and spreading ever since.  I have noticed that my nursery customers have the same reaction that I did: what is that plant—is an annual?  So I thought I would introduce it to all my readers and recommend it for inclusion in your gardens.



When I say they are like a begonia house plant, I am not kidding.  They grow from tuberous roots and have fleshy succulent stems.  Their leaves are 3 to 6″ long and shaped like an angel’s wing with green on top and red highlights underneath.

The flowers are pale pink and clustered in loose bunches with deep pink stalks.  They bloom from September into November depending on when we get a frost.  The ovary, which persists when the flowers drop, is bright pink, three-winged, and very attractive.

Self-sown hardy begonias in my compost pit

Hardy begonia is native to China and Japan.  It is an upright plant growing to 2 to 3 feet in part to full shade.  Ideally it likes organic, moist soil, but my experience is that it grows anywhere in the shade.  It spreads all over the place at Carolyn’s Shade Gardens and is easily removed by yanking on the stem.  However, I rarely find it in a place I don’t want it.  It has even formed a very nice stand in my compost pit.  The only trick to growing it is that it comes up very late—mid-May in the mid-Atlantic—so you need to remember where it is.

White hardy begonia, B. grandis ‘Alba’

 

There is a lovely white cultivar of hardy begonia called ‘Alba’.  It has pure white flowers with pale pink stalks.  It is just as hardy as the parent species and seeds around my garden readily.


Hardy begonia looks great everywhere in my garden.  However, I prize it for growing between all my hostas on my back hill.  When the hostas look ratty, it springs up looking fresh and elegant and blooms its heart out.

Before I start an avalanche of emails asking for this plant, I am sold out for the year at the nursery.  However, I always have it available in the spring so look for it in 2013.

Woody Plants for Shade Part 6

Posted in Camellias, evergreen, Shade Gardening, Shade Shrubs, winter interest with tags , , , , , , , , , , , , , , , , , , , , on September 28, 2012 by Carolyn @ Carolyns Shade Gardens

‘Early Amethyst’ beautyberry, Callicarpa dichotoma, is available in the current offer but was profiled in a previous woody plant post so I am not describing it here.  However, it is a favorite for fall interest and I wanted to include a photo.  For a full write up of this plant,  go to Woody Plants for Shade Part 3.

My nursery, Carolyn’s Shade Gardens, specializes in perennials for shade with an emphasis on hellebores, unusual bulbs especially snowdrops, hostas particularly miniature hostas, native plants, and ferns.  However, a satisfying shade garden does not consist of just perennials but includes trees, shrubs, and vines.

‘Winter’s Joy’ fall-blooming hardy camellia is another repeat, see this post for details.  I planted one myself last fall, and I would like to add to my previous write up that this camellia has more buds and flowers than any other camellia in my garden.  In 2011, it produced the beautiful flowers pictured above through out the entire winter.  Right now my plant is poised to do it again with hundreds of buds waiting to open.

Despite the need, woody plants for shade are difficult to find in local nurseries.  To fill this gap for my customers, three times a year, I offer woody plants for pre-order.  The plants chosen for the offer are the result of hours of painstaking selection in the shade houses of wholesale nurseries to find the healthiest, most desirable woodies available.


‘Winter’s Snowman’ fall-blooming hardy camellia is another favorite offered previously, see this post for details.  I have written three articles about fall-blooming hardy camellias in general.  If you are interested in finding out more about them, start here Fall-blooming Hardy Camellias Part 3, and you will find links to the first two installments.

 It is now time for my fall 2012 woody offer.  If you are a customer, you should already have gotten an email with all the details.  Blog readers can look at the catalogue on line by clicking here.  My nursery is on site retail sales only.  The only plants I ship are snowdrops in February and miniature hostas later in the season.  However, I hope out-of-town readers will get some good ideas for woody shade plants to look for at their local independent nursery.

The previous three photos are of another repeat: paper bush, Edgeworthia chrysantha, for details click here.  My plants have thrived through the last two hot and dry summers with pristine tropical looking leaves, gorgeous fall-forming buds, and highly fragrant late winter-blooming flowers.  This is truly a shrub with 365 days of interest.

So much for the preliminaries and repeat offerings, let’s get to the new plants.  There are six: three from my favorite group of shrubs, hydrangeas, and three evergreens for winter interest (the camellias are evergreen too).  Here are the details.

Native oakleaf hydrangea, H. quercifolia

The fall color of oakleaf hydrangea.

Our native oakleaf hydrangea, H. quercifolia, is the best all round shrub for shade—everyone should have at least one!  Huge, long-lasting, upright pyramids of white flowers bloom from May through July. It has bold-textured leaves with heart-stopping burgundy-red fall color, and cinnamon-colored exfoliating bark—a true four season plant. 

The white flowers of ‘Amethyst’ oakleaf hydrangea age to a striking red that does not fade when dried.  Great for flower arranging.

I am offering ‘Amethyst’ native oakleaf hydrangea, a new cultivar selected because  its initially white flowers turn to a striking red color and stay that way.  It grows to 5 to 6’ tall and 5 to 6’ wide in sun to full shade.  It is hardy in USDA hardiness zones 5 to 9, walnut and drought tolerant, and native to the southeastern US.

 

‘Blue Bird’ sawtooth hydrangea, H. serrata


‘Blue Bird’ sawtooth hydrangea produces lovely blue lacecap flowers starting in June for an extended period.  Acid soil results in the best blue tint.  I also grow it for its beautiful clean bright green leaves through out the season, which are enhanced by red highlights in the fall.  It is very tolerant of cold temperatures avoiding bud and twig dieback in harder winters.  ‘Blue Bird’ reaches 4′ tall and 4′ wide in part to dappled shade and grows in zones 5 to 9.  Sawtooth hydrangea is native to Korea and Japan.

This photo shows ‘Endless Summer’ bigleaf hydrangea, H. macrophylla, right now.  Yes, it is loaded with fresh flowers and buds and has been blooming since late spring.

‘Endless Summer’ bigleaf hydrangea sports very large pink or blue mophead flowers from late spring through summer and well into fall—it’s in full bloom right now as you can see from the photo above.  It represents a recent breakthrough in hydrangeas because it blooms on old and new wood giving it an extended bloom season.  This also means that if the buds formed on old wood the previous season are frozen over the winter, buds will form on new wood as the season progresses.  ‘Endless Summer’s’ large, medium green leaves provide a pleasing backdrop for the flowers.  It grows in zones 4 to 9 and reaches 4′ tall and 4′ wide in part shade.  It is recommended for full sun only with supplemental watering.  Bigleaf hydrangea is native to Japan.

‘Gold Dust’ Japanese aucuba, A. japonica, is an elegant specimen for deep shade.

A close up of the unusual leaves of ‘Gold Dust’ Japanese aucuba—glorious in winter.

‘Gold Dust’ Japanese aucuba’s very shiny, broadleaf evergreen leaves sprinkled with yellow spots make it one of the most vibrant and colorful plants to thrive in dense shade.  I have grown it successfully for many years in several areas of my garden that receive no direct sunlight.  It is very vigorous, disease free, and easy to grow as long as you don’t plant it in the sun.  ‘Gold Dust’ grows to 6 to 8′ tall and 4 to 6′ wide in part to dense full shade and is hardy in zones 7 to 9.  Aucuba is native to Japan, and the variegated form was introduced to the west in 1783.

The fall flowers of ‘Rose Creek’ glossy abelia, A. x grandiflora.

‘Rose Creek’ is a compact form of glossy abelia, great for smaller spaces and smaller gardens.

‘Rose Creek’ is a dense and compact glossy abelia that covers itself in a multitude of wonderfully fragrant, showy white flowers continuously from May through September.   When the flower petals drop off, the rosy pink sepals (bud enclosures) remain and are very eye-catching.  The beautiful, glossy evergreen foliage has pink highlights and turns purple in the fall, providing excellent winter interest.  The stems are  crimson red.  ‘Rose Creek’ grows to 2 to 3′ tall and 3 to 4′ wide in part shade or full sun and is hardy in zones 5 to 9.  It is deer resistant and attracts butterflies and hummingbirds.  Glossy abelia is a cross between two Chinese abelia species.

The incredibly shiny leaves of Prague viburnum, V. x pragense, sparkle in the winter.

This photo of the flower of Prague viburnum was kindly lent to me by Monrovia, for their full plant profile, click here.

Prague viburnum’s pink buds open into large, bouquet-like, creamy white flowers in May followed by glossy, persistent black fruit.  Just as ornamental are its very showy, lustrous, dark evergreen leaves.  Prague viburnum reaches 8′ tall and 6′ wide in full sun to part shade and is hardy in zones 5 to 8.  You can grow it in full shade and the leaves will be gorgeous, but it won’t flower very well.  It is fast growing and deer resistant.  It is a cross between leatherleaf and service viburnums, which are both from China.

I hope you have a space in your garden for at least one of these wonderful shrubs for shade.  For more ideas, check out Woody Plants for Shade Parts 1 to 5 using the links provided below:
