Leucojum aestivum, Stylophorum diphyllumSummer snowflake with Celandine poppy in the woodland at Carolyn’s Shade Gardens.

The 2019 Snowdrop Catalogue is on the sidebar, and we are taking orders, to access the catalogue please click here.

When snowdrops are finishing, their close relatives, snowflakes (Leucojum),  are ready to take over the display.  They are quite beautiful, but haven’t been subjected to the intense selection process that has resulted in over 1,500 snowdrop cultivars.  They are very easy to grow, and I think they deserve more attention.

Leucojum aestivum, Stylophorum diphyllum 4-26-2015 6-43-58 PMLeucojum aestivum in my woodland in April.

.

There are two main species of snowflakes: Leucojum aestivum or summer snowflake and Leucojum vernum or spring snowflake.  Summer snowflake blooms in April in our area so the common name is very confusing.  It is a large and vigorous plant reaching 12 to 18 inches with multiple green-tipped, white, lantern-shaped flowers at the end of each flower stem. 

It likes moist soil but grows quite well in my dry woodland as you can see from the photos.  It grows in dappled woodland conditions but also quite sunny spots and seeds aggressively in my garden.  Summer snowflake is native to Central and Eastern Europe.  The cultivar ‘Gravetye Giant’ has bigger flowers, but I have not grown it.

 Spring snowflake

Spring snowflake, Leucojum vernum, blooms in March in our area so it could easily be called winter snowflake. On its own, it is a diminutive plant reaching 6 to 9 inches with single, green-tipped, white, lantern-shaped flowers at the end of each flower stem.  The leaves are strap-shaped and a very pretty glossy, bright green.  It likes moist soil but grows quite well in average moisture conditions in deciduous shade to part shade locations.  Spring snowflake is native to Central and Southern Europe.

Although unassuming as a single plant, spring snowflake is breath-taking when massed as the following photos show:

There are some named forms of Leucojum vernum, which are quite interesting:

.

Leucojum vernum Ithan Park 3-17-2016 5-20-19 PM

Leucojum vernum var. wagneri (or vagneri) produces two flowers on each stem, although none of mine did that this year.  I have read that it is no longer a valid variety.  If you visit naturalized populations of Leucojum vernum, a certain percentage will have twin flowers. This photo shows a wagneri with standard-shaped flowers and green spots.

.

Leucojum vernum var. wagneri

This wagneri has the yellower spots typical of var. carpaticum pictured below.

.

Leucojum vernum var. carpathicum

Leucojum vernum var. carpaticum has yellow spots on each petal instead of the normal green spots.

.

Leucojum vernum 'Null Punkte'

‘Null Punkte’ from Germany is pure white with no spots.

.

Leucojum vernum 'Gertrude Wister' Cresson garden

‘Gertrude Wister’ is a semi-double spring snowflake with 12 or more petals instead of the normal 6.  It was discovered by noted bulb expert Gertrude Wister in her garden on the Swarthmore College campus in Pennsylvania, US.

Mertensia virginica, Stylophorum diphyllumNative Virginia bluebells, Mertensia virginica, and native Celandine poppies, Stylophorum diphyllum, are two of my favorite plants for spring and are wonderful combined with almost anything.  Very easy to grow in part to full shade and woodland conditions.

In April 2011, I wrote a post about beautiful spring pairings.  To read it, click here.  I always meant to continue the topic and have finally taken the time to photograph the garden.  Some of the combinations are the same but that’s because I love them!

Longwood Gardens Part 5: Tulips and Natives

. 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.

.

Trillium grandiflorum 'Quicksilver' and Anemonella thalictroides‘Quicksilver’ surrounded by rue-anemone.

Trillium erectum, purple trilliumpurple trillium, T. erectum

.

Trillium erectum, purple trilliumThe two-tone flowers of purple trillium are gorgeous.

.

Dicentra cucullaria, squirrel cornsquirrel-corn, Dicentra canadensis

.

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.

.

Caulophyllum thalictroides and Dicentra canadensisBlue cohosh can act like a small shrub, here with an underplanting of squirrel-corn.

.

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.

.

stump in Peirce's WoodsI thought what Longwood had done to the stump of a tree that came down was very interesting and actually quite attractive.

.

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.
