The bright rose flowers of ‘Wine & Roses’ old-fashioned weigela.

Shade gardens are not composed solely of perennials so two years ago I branched out to offer high quality shrubs, vines, and trees to my customers.  In my second Spring 2012 Woody Plant Offer, details here,  I have focused on plants that are late spring or summer blooming and native to our area.  I thought my blog readers who are not customers might be interested in learning about the plants that I would recommend they add to their shade gardens.  And doing an article allows me to add more information and explain why I chose the plants I included so customers might be interested also.

When it blooms in late spring, our native fringe tree is covered with elegant, fragrant flowers.

Fringe tree is a lovely small flowering tree or a large shrub.

I saw native fringe tree, Chionanthus virginicus, in full bloom in the shady woods of Bartram’s Garden in Philadelphia recently, and it reminded me of how gorgeous this native tree is.   It is loaded with generous amounts of creamy white, fragrant flowers in May and June.  Its medium green leaves turn a good yellow in the fall.  It may produce showy grape-like fruit attractive to birds.  Fringe tree grows to 12 to 20’ tall and 12 to 20’ wide in sun to part shade, although the tree in Bartram’s Garden was in a very shady site.  It is wet site tolerant, hardy to zone 4, and native to the eastern US, including PA.  It is a  Missouri Botanical Garden Plant of Merit (photos courtesy of MOBOT).

 

 Our native dwarf summersweet is loaded with fragrant white flowers in summer.

I have seen stands of summersweet growing wild in New England, and it is a beautiful sight.  However, the species gets quite large and suckers into colonies so the native dwarf summersweet ‘Hummingbird’Clethra alnifolia ‘Hummingbird’, is better for most home gardens.  It has very fragrant, bottlebrush, white flowers in June and July that attract butterflies.  Its  lustrous bright green leaves turn a clear yellow in the fall.  It has an excellent compact habit and produces more flowers than the species.

Dwarf summersweet’s habit is much more compact and attractive than the species, and it produces more flowers.

Dwarf summersweet grows to 2 to 4’ tall and 3’ wide in sun to full shade.  It is hardy to zone 4, deer resistant, wet site and salt tolerant, and native to the eastern US, including PA.  It is a Pennsylvania Horticultural Society Gold Medal Plant,  click here for details (photos courtesy of the MOBOT Plant Finder, for more information click here).


 ‘Nikko’ dwarf slender deutzia is loaded with white flowers in late spring.

‘Nikko’ lining my rock garden path in full shade.

I have offered ‘Nikko’ dwarf slender deutzia, D. gracilis ‘Nikko’, before, but it is such a useful plant that I couldn’t help including it again.  It is covered with delicate white flowers in April and May.  Its fine-textured and neat green leaves turn an attractive burgundy in the fall.  It is an excellent specimen or flowering groundcover for shade.  I grow it in full shade as a groundcover to edge the path at the base of my winterberry hollies.  ‘Nikko’ grows to 1 to 2’ tall and 2 to 5’ wide in full sun to full shade.  It is hardy to zone 4 and deer resistant.  It is a PHS Gold Medal Plant (for more information click here).


 ‘Invincibelle Spirit’ is a color breakthrough for our native smooth hydrangea.

Native ‘Invincibelle Spirit’ smooth hydrangea, H. arborescens ‘Invincibelle Spirit’, is  a pink-flowered version of the wonderful ‘Annabelle’.  It has very showy large pink snowball flowers that continue to bloom from June into the fall.  ‘Invincibelle Spirit’ grows to 3 to 4’ tall by 3 to 4’ wide in part to full shade.  It is hardy to zone 4, tolerant of a wide range of soil conditions, deer resistant, and native to the eastern US, including PA.  It should be gently pruned in late spring for optimum growth (photo courtesy of the MOBOT Plant Finder, for more information click here).                    

A close up of the large and beautiful flowers and leaves of oakleaf hydrangea.

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 and change to pink for even longer interest.  It has bold-textured leaves with heart-stopping burgundy-red fall color, and cinnamon-colored exfoliating bark—a true four season plant.  I am offering ‘Alice’ native oakleaf hydrangea, a superior form that has larger flowers, better fall color, and very disease resistant leaves.  It grows to 5 to 8’ tall and 5 to 8’ wide in sun to full shade.  It is hardy to zone 5, walnut and drought tolerant, and native to the southeastern US.  For more information, click here.


The pink mophead flowers of ‘Preziosa’ age to a dark maroon.

‘Preziosa’s’ leaves are gorgeous, here they are starting to turn burgundy in the fall.

‘Preziosa’ sawtooth hydrangea, H. serrata ‘Preziosa’, is now my favorite “fancy” hydrangea for full shade so I am offering it again.  I planted mine in the shade of a white pine under a cherry laurel behind a Japanese maple, and it is thriving and loaded with buds right now.  This wonderful hydrangea produces lovely pink mophead flowers from June to August, which darken with age to a gorgeous maroon.  But I may like the elegant leaves more, especially their beautiful burgundy fall color.   The leaves, deep red stems, flowers, and habit of ‘Preziosa’ are all superior to most other hydrangeas.  ‘Preziosa’ grows to 3 to 4’ tall and 3 to 4’ wide in part to full shade.  It is very tolerant of cold temperatures and hardy to zone 5.  For more information, click here.



 The elegant leaves and flowers of native ‘Blue Muffin’ arrowwood viburnum.

Native ‘Blue Muffin’ arrowwood viburnum, V. dentatum ‘Blue Muffin’,  has lovely flat-topped white flowers in May and June that attract butterflies.  Lots of pea-sized very blue berries appear in late summer and attract birds.  The shiny dark green leaves are beautiful all season and turn attractive shades of orange to burgundy in the fall.  ‘Blue Muffin’ has an excellent and useful narrow, upright habit.  The branches are so straight that the Native Americans used them for arrows. 

‘Blue Muffin’s’ blueberry-like fruit.

‘Blue Muffin’ grows to 5 to 8’ tall and 3 to 4’ wide in sun to part shade.  It is deer resistant and grows in a wide range of soils.  It tolerates salt, drought, and walnuts.  ‘Blue Muffin’ is hardy to zone 3 and native to the eastern US, including PA (fruit photo courtesy of MOBOT, for more information click here).

 The flowers of ‘Wine & Roses’ weigela.

‘Wine & Roses’ old-fashioned weigela, W. florida ‘Wine & Roses’, has copious amounts of eye-catching rose-red flowers in May and June that attract hummingbirds.   The flowers are set off to perfection by the glossy deep burgundy leaves whose color intensifies in the fall.  ‘Wine & Roses’ has an excellent habit—you can prune it immediately after flowering to fit any location.  It grows to 4 to 5’ tall and 4 to 5’ wide in sun to part shade.  Although I recommend some direct sun for better flowers, I have seen weigela blooming in full shade.  It is hardy to zone 4, deer resistant, and tolerant of a wide range of soils.  ‘Wine & Roses’ is a PHS Gold Medal Plant, for details click here.


The silver leaves of ‘Moonlight’ Japanese climbing hydrangea.

The flowers of Japanese climbing hydrangea—here the straight species.

‘Moonlight’ Japanese hydrangea vine, Schizophragma hydrangeoides ‘Moonlight’, has very showy 8 to 10” wide white lacecap flowers  in midsummer.  But I really grow it for its elegant silver-painted dark green leaves, which turn yellow in the fall.  ‘Moonlight’ is a self-attaching vine that covers the surface it grows on with silvery leaves.  It reaches 20 to 30’ at maturity in part to full shade—mine is in deep shade.  It is a PHS Gold Medal Plant, for details click here (photo of flowers courtesy of the MOBOT Plant Finder click here).

Woody Plants for Shade Part 3

‘Winter’s Joy’ Fall-blooming Hardy Camellia

My nursery specializes in herbaceous flowering plants for shade.   However, although no shade garden is complete without trees, shrubs, and vines, our local nurseries seem to ignore woody plants for shade.  To fill this gap, I offer my customers shade-loving woodies from a wholesale grower whose quality meets my exacting standards.  As in Woody Plants for Shade Part One and Woody Plants for Shade Part Two, I thought my blog readers who are not customers might be interested in learning about the woody plants that I would recommend they add to their shade gardens.  And doing an article in addition to the customer offering allows me to add more information so customers might be interested also.

This summer was tough on plants.  I lost several shrubs that I planted this spring.  That is why fall is the best time to plant.  The soil temperature is elevated for good root development through December, but new plants don’t have to contend with scorching temperatures, severe drought, or an excess of rain.  The plants that I add in the fall are always the most successful in my garden.

Included in my offering are three evergreen shrubs, five deciduous shrubs, and one vine.  Of the nine plants I have chosen, three are native.  Please read my article My Thanksgiving Oak Forest to see why I think planting native plants is crucial to our environment.  My article New Native Shade Perennials for 2011 explains why I think native cultivars are valuable native plants.  With that introduction, here are the plants I am offering highlighted in green:

The fall-blooming camellia ‘Winter’s Snowman’ shines in the winter sun.

If you have been reading my blog, you know that I love camellias, especially fall-blooming varieties.  There is nothing like going outside on a cold November or December day and being greeted by large showy flowers backed by gorgeous evergreen leaves.  Camellias really light up the shadiest parts of my garden during the time of year when flowers are most appreciated.  For more information on and some beautiful photographs of fall-blooming hardy camellias, see my articles Fall-blooming Camellias Part 1 and Fall-blooming Camellias Part 2.


‘Winter’s Snowman’ blooming in December

In a very shady place on the terrace outside my front door, I have a ‘Winter’s Snowman’ fall-blooming hardy camellia.  At maturity, it will reach six feet.  Its semi-double white flowers glow when displayed against the glossy evergreen leaves in November and December.  It is a vigorous plant with a narrow upright habit.  Although it is fully hardy in our area, I have sheltered it from winter sun and our winter winds, which come from the northwest.


‘Winter’s Joy’ fall-blooming camellia

In a similarly sheltered and shady location outside my back door along the path to my compost “pit”, I have planted another fall-blooming camellia.   ‘Winter’s Joy’ fall-blooming hardy camellia has semi-double, fuchsia-pink flowers elegantly displayed against glossy evergreen leaves in November and December.  It is a vigorous plant with a narrow upright habit, reaching six feet at maturity.  Right now both these fall-blooming camellias are covered with buds.  I can’t wait for the display to begin.

‘Winter’s Joy’ is loaded with buds just waiting to produce its showy flowers, and look at that immaculate foliage.

I really like leatherleaf viburnums.  They are evergreen, deer resistant, grow in full shade, have lovely flowers and foliage, and are big enough to screen unsightly views.  The plants I have in my garden are the straight species Viburnum rhytidophyllum and that’s what I intended to offer to my customers.  However, when I saw ‘Dart’s Duke’ lantanaphyllum viburnum (what a name!), V. x rhytidophyllum ‘Dart’s Duke’, and did some research, I realized it is a superior plant for foliage, flowers, berries, and vigor.   A comparison of the nursery stock confirmed this.

‘Dart’s Duke’ showing its majestic leaves and reblooming to produce some of its very large flowers for fall.

‘Dart’s Duke’ grows to 8’ tall by 8’ wide in full sun to full shade.  It has very large, 6 to 10”, showy white flowers in May and can rebloom in the fall.  The flowers are followed by very nice red fruit.  The beautiful, clean dark green, leathery evergreen foliage is deer resistant and winter tough.  It is a Pennsylvania Horticultural Society Gold Medal Plant for 2012, one of only four plants honored.


‘Early Amethyst’ beautyberry is dispalying its amazing purple berries right now at Carolyn’s Shade Gardens.

‘Early Amethyst’ beautyberry, Callicarpa dichotoma ‘Early Amethyst’,  has attractive pink flowers in spring.  But the real show is in the fall when huge amounts of unbelievably colored purple berries run down the center of the beautifully layered branches.  When the leaves drop, the persistent berries are even more showy though they are attractive to birds.  Beautyberry reaches 4’ tall by 4′ wide in sun to part shade and is deer resistant.  I have grown this plant successfully in part shade for years.  If desired, it can be cut back in spring, but I usually leave mine alone.  Beautyberry is a Pennsylvania Horticultural Society Gold Medal Plant and Missouri Botanical Garden Plant of Merit.

Paper Bush, Edgeworthia chrysantha

Paper bush, Edgeworthia chrysantha, is a rare and unusual shrub that has just been discovered by collectors within the last few years.  However, it has so many great ornamental features that it is sure to become very popular.  Its very fragrant clusters of tubular bright yellow flowers bloom from January to March.  The buds, which form in the fall, are as ornamental as the flowers.  They remind me of the tassels on the corners of Victorian pillows.  Paper bush has an elegant and symmetrical upright, branching habit, growing to 6’ tall in part to full shade with protection from winter winds.  It is an exquisite and rare shrub that is ornamental 365 days of the year in my garden.

The buds of paper bush are ornamental all winter.

The unusual fragrant flowers of paper bush

The flowers of ‘Preziosa’ sawtooth hydrangea start out a lovely pink and mature to a bright maroon.

‘Preziosa’ sawtooth hydrangea, Hydrangea serrata ‘Preziosa’, produces numerous lovely pink, small, mophead-like flowers in June and July, which darken with age to a gorgeous maroon (see link below for photo).  The flowers are reliably pink and don’t turn blue.  The beautiful burgundy fall color of the leaves and stems only adds to the show.  ‘Preziosa’ reaches 4’ tall and wide in part to full shade.  The Hydrangea serrata species is one that thrives in full shade.  Unlike many hydrangeas, ‘Preziosa’ is very tolerant of the cold temperatures in our zone 6.  For a raving review of ‘Preziosa’ and more cultural information (note that the winter protection recommended is for zone 5), click here.

The leaves of ‘Preziosa’ sawtooth hydrangea have already started to turn burgundy.

This photo shows the berries on my ‘Red Sprite’ winterberry holly right now—they get much larger as the season progresses, but the show is already breathtaking.

One of my all time favorite native plants is winterberry holly, Ilex verticillata.  It grows wild all over the island in Maine where my family vacations and is always covered with berries in the fall.  Here in Pennsylvania, my preferred winterberry holly cultivar is Ilex verticillata ‘Red Sprite’.  It produces copious amounts of very large red berries on relatively compact plants that never need pruning.  The birds love the berries too, but they leave enough behind for it to remain extremely showy late into the winter.  ‘Red Sprite’ reaches 5’ tall in sun to part shade and is wet site and salt tolerant, and deer resistant.  All hollies require a male pollinator, in this case ‘Jim Dandy’, for good fruit set.  Winterberry is native to the entire eastern half of North America, including Pennsylvania.


The flowers and foliage of native ‘Cool Splash’ southern bush honeysuckle, Diervilla sessifolia ‘Cool Splash’

‘Cool Splash’ southern bush honeysuckle is a native shrub whose bold green and white variegation really stands out in the shade.  Its honeysuckle-shaped yellow flowers appear in July and August with rebloom in the fall.  ‘Cool Splash’ grows to 4’ tall and wide in sun to part shade.  It is tough, cold hardy, and deer resistant, and integrates well into perennial borders.  This species is native to the southeastern U.S., but a closely related species, D. lonicera, is native to Pennsylvania.  It is one of four plants honored with a gold medal by the Pennsylvania Horticultural Society in 2011.  Nan Ondra at the blog Hayfield has written an excellent profile of this native shrub (with many photos), click here .

In late spring and early summer, ‘John Clayton’ trumpet honeysuckle is covered with these delightful tubular yellow flowers attractive to hummingbirds.

I love vines, and one of my first acquisitions was the native ‘John Clayton’ trumpet honeysuckle, Lonicera sempervirens ‘John Clayton’.  It is my most vigorous trumpet honeysuckle vine, completely covering the lattice under my deck.  Its bright yellow tubular flowers are beloved by  hummingbirds in late spring and early summer and  rebloom through fall, forming attractive red berries.  ‘John Clayton’s’ semi-evergreen, bright green leaves remain attractive through the season.  It reaches 10’ in sun to part shade.  It is deer resistant and very low maintenance.  Trumpet honeysuckle is native to the eastern U.S., including Pennsylvania.

I grow most of these plants in my gardens so I know you can’t go wrong by adding them to yours!  If you are a customer, see Nursery Happenings below for details on how to order these wonderful shade plants.  If not, now you have some plants to ask for at your local independent nursery.
