Our woodland is spectacular right now.  Here, ‘Royal White’ redbud, Cercis canadensis, underplanted with golden groundsel, Senecio (Packera) aureus.

More and more of our customers are becoming interested in native plants, which we have been promoting since we opened our nursery in 1992.  If you would like to know more about why growing native plants is important to our survival, click here.  Every plant in this post is native to Southeastern Pennsylvania unless noted.

Our woodland garden, which is filled predominantly with native plants, is in full bloom right now.  If you would like to see a video of our woodland in bloom, there is one on our Facebook page here, just scroll down past upcoming events to videos.  Meanwhile, I am going to highlight some of the natives in our woodland in this post.

I am dedicating this post to the volunteers and career emergency personnel at Narberth Ambulance and all the ambulance workers all over the country who are risking their lives daily to help people with COVID-19.  In the face of their dedication, any sacrifice that we are asked to make seems minor.  Please stay home to save lives.  For an inside look at what ambulance workers face right now, please read this excellent article from the Philadelphia Inquirer by clicking here.

.Celandine poppies, Stylophorum diphyllum, in the front with golden groundsel in the back.  Both of these plants should only be grown in a naturalized garden where they can spread.  Golden groundsel is a great native substitute for non-native groundcovers like pachysandra, ivy, or vinca.  It is evergreen, has beautiful flowers suitable for cutting, grows in even the most difficult site, and covers the ground completely.

.

‘Blue Ridge’ creeping phlox, P. stolonifera, also makes a great evergreen groundcover.  ‘Blue Ridge’ is not as vigorous as some of the other creeping phlox cultivars, which can be an advantage if you have a small space.

.

Virginia bluebells, Mertensia virginica, are going by right now, but their true blue flowers have been a highlight for the last two months.  They go dormant when it gets hot out.

.

Dwarf Jacob’s ladder, Polemonium reptans, in the front with blue flowers, and wild ginger, Asarum canadense, right center under the native dogwood, have moved around on their own to fill large swaths of our woodland.

.

‘Mocha’ coralbells, Heuchera villosa, on the right, western wild ginger, Asarum caudatum (native to the west coast), on the left, surrounded by creeping phlox, P. stolonifera.

.There are pink-flowered cultivars of creeping phlox called ‘Home Fires’ and ‘Pink Ridge’, but this is the straight species.  My customers didn’t buy it last year as it is so vigorous it doesn’t look as appealing in the pots as the other creeping phlox cultivars.  I planted 12 leftover, quart-sized pots, and they completely filled in this large area in one year.

.Little sweet Betsy or bloody butcher, Trillium cuneatum, is my favorite of the many trilliums in our woodland.

.Great white trillium, T. grandiflorum, has been seeding through out our patch of white violets, Viola striata.  White violets make a great groundcover as they fill in completely and are one of the longest blooming plants in out woodland.

.

‘Sherwood Purple’ creeping phlox surrounds a small grove of ‘Blue Shadow’ fothergilla, F. x intermedia.

.

This large “river” of ‘Sherwood Purple’ creeping phlox hosts many of the special snowdrops in my collection in late winter and then produces its lovely purple flowers for a long time in early spring.  ‘Sherwood Purple’ is another creeping phlox that makes an excellent groundcover.

.

‘Lynnhaven Carpet’ robin’s plantain, Erigeron pulchellus, has fuzzy, silver-highlighted leaves and daisy-like flowers.

.

‘Lynnhave Carpet’ spreads quickly to form a weed-choking groundcover.

.

Our woodland is almost all native plants with a very narrow path through the center covered in white pine needles.

Senecio aureus

Golden groundsel, Senecio aureus, is the best native plant for ground cover.

I write a lot about the things we do at Carolyn’s Shade Gardens to support the environment: gardening organically without herbicides and chemical fertilizers, doing little supplemental watering, composting, mulching with ground leaves, getting rid of our lawn, landscaping with large quantities of native plants, and promoting natives at the nursery.

Carolyn's Shade Gardens Woodland

Our native white-flowered redbud surrounded by native plants.

You can read more about these practices in these posts among others:

Carolyn's Shade Gardens woodland

Our woodland in April with Virginia bluebells, wild ginger, golden groundsel, and mayapples—all native.

My guide to creating a native woodland has been especially popular.  However, most gardeners don’t have vast areas of woods to convert to native plants but still want to make a difference.  And I am sure that most people realize that planting three milkweed plants, though admirable and to be encouraged, is not going to save the monarch butterflies.  So what can you do? 

.Viola striata

Native white violets, Viola striata, used in quantity as an edging along the front of a border.  The violets spread rapidly by seed, filling in empty areas and preventing weeds.

One solution is to find ways to include large quantities—a critical mass—of native plants in your garden, no matter what size.  You can accomplish this by replacing non-native ground covers like pachysandra, vinca, ivy, euonymus, and turf grass with native ground cover plants.  It is easy to do and you can start small by using spreading native plants like the violets above as edging for your existing beds.  Soon you will be eliminating whole swathes of your lawn!  Here are some more ideas of plants to use:

.
Phlox subulata 'Purple Beauty'
Native ‘Purple Beauty’ moss phlox, P. subulata, used as an edging.
.

Phlox subulata 'Emerald Blue'

This patch of native ‘Emerald Blue’ moss phlox has been in place for at least a decade and requires no maintenance at all.  It is evergreen so is present year round like pachysandra but provides you with beautiful flowers and the native insects with food.  Its mat-like habit excludes all weeds.

.

Phlox subulata 'Nice 'n White'

Native ‘Nice ‘n White’ moss phlox used to replace non-native vinca, which you can see behind it.  This location is quite shady and the moss phlox thrives.  All it needs is good drainage.

.

Phlox subulata 'Nice 'n White'

Our original planting of native ‘Nice ‘n White’ moss phlox is filling in to create a solid blanket while we continue to move down the hill adding new plants.

.

Iris cristata 'Tennessee White'

Native ‘Tennessee White’ dwarf crested iris, Iris cristata, used to edge our raised beds.  I expect these clumps to double in size by next spring.

.

Senecio aureus

Native golden groundsel, Senecio aureus, the yellow flower in the photo above and the first photo, makes the best ground cover of any native plant.  It spreads aggressively and is evergreen and mat-forming like pachysandra but also produces beautiful, fragrant flowers suitable for cutting.  Like pachysandra it is too aggressive to be mixed with other plants, but unlike the pachysandra in our area it is not subject to alfalfa mosaic virus.

.

Chrysognum virginianum 4-26-2016 11-47-39 AM

Native goldenstar, Chrysogonum virginianum, is another creeping plant that makes a good edger.

.

Chrysognum virginianum 4-26-2016 11-47-51 AM

Because the goldenstar was working so well at the edge, we decided to replace a whole section of our lawn with it.

.

Phlox stolonifera 'Sherwood Purple'

Two years ago we replaced another section of our lawn with native ‘Sherwood Purple’ creeping phlox, P. stolonifera.  This phlox grows in part to full shade and forms a flat, weed-choking mat that stays green all winter.

.

Aster cordifolius

Native blue wood aster, Aster cordifolius, replaced another section of lawn at Carolyn’s Shade Gardens that surrounded a gigantic black walnut.

.

Aster cordifolius

Native blue wood aster blooms in the fall and grows in part to full shade.

.

Doug Tallamy explains in his amazing book Bringing Nature Home* that we can make a difference for the environment and the plants and animals (including us) which are struggling to survive there, by planting native plants in our suburban gardens.  I hope I have given you some good ideas for accomplishing this laudable goal.

Your Native Woodland: If You Build It They Will Come

Posted in Fall Color, groundcover, landscape design, native plants with tags , , , , , , , , , , , , , , , , , , , , , , on April 2, 2012 by Carolyn @ Carolyns Shade Gardens

Virginia bluebells and Celandine poppy in my woodland

Well you might have to plant a few first.  What am I talking about?  How to create your very own woodland filled with native plants.  I have written before about how important native plants are to our survival.  To read about it, click here.  Now I am going to tell you how to create a shade garden in which mid-Atlantic native plants thrive and multiply with abandon.

Note: There is a Part 2 with more suggestions, click here.

my native woods

It is really quite simple.  All you do is take one woodland area, mix with generous amounts of compost, add the appropriate native plants, and wait a few years.  The key is knowing which plants to use.


I started with the worst possible soil in the worst possible conditions.  Not only were the beds composed of the hard baked clay and rocks prevalent in our area, but they were filled with roots from 100-year-old London plane and—hold onto your hats—black walnut trees.  Add to that, years of trash, including roofing slate and coal furnace shovelings, dumped in the woods before municipal collection came along and construction debris from the 1960s.


Nature does not dot the landscape with precious collectibles but  “designs” with large sweeps of single types of plants, and that is what I have done in my woods  To create a woodland like mine, all you do is plant at least five but preferably seven and ideally nine of the plants profiled below in beds amended with generous amounts of compost, mulch heavily with ground leaves, and stand back and wait.  Really….that’s what you do….it works.

 

I wanted to recommend six plants, but when it came down to slimming the competition, I had to go with nine: seven spring-blooming and two fall-blooming.  All are native to the mid-Atlantic and Pennsylvania and all seed freely in a woodland setting once they get going.  And the winners are:

Virginia bluebells, Mertensia virginica: porcelain blue flowers top blue-green leaves in March and April, goes dormant when hot.  All my plants came from one plant given to me by a friend.

 

Celandine poppy, Stylophorum diphyllum: lovely filigreed leaves are covered with large bright yellow flowers in April and May.  Again, all my plants came from one plant given to me by a friend.

Dwarf Jacob’s ladder, Polemonium reptans: wintergreen fern-like leaves are followed in April and May by copious blue bell-shaped flowers replaced by ornamental chartreuse seedpods.

.

White violets, Viola striata: white flowers in April and May.  All my plants came from one clump dug from my woods.

 

Blue creeping phlox, Phlox stolonifera ‘Blue Ridge’: wintergreen mat of foliage is topped with blue flowers in April and May.

 

Creeping phlox, Phlox stolonifera ‘Sherwood Purple’: creeping phlox comes in blue, purple, white, and pink.  The purple is the most vigorous.

 

Native ginger, Asarum canadense: the reddish purple flowers appear below the leaves.

 

Golden groundsel, Senecio aureus: the wintergreen leaves are topped by attractive purple buds in March followed by fragrant yellow flowers in April and May.  This vigorous spreader is a great native substitute for vinca, pachysandra, and ivy.

Blue wood aster, Aster cordifolius: the leaves of blue wood aster completely cover the ground in the spring.

 

Blue wood aster is covered with flowers in October and November.

Northern sea oats, Chasmanthium latifolium: pendulous oat-like flowers grace this native shade grass in October and November.  The foliage ages to a lovely khaki color that remains ornamental through winter.

The flowers of northern sea oats in the slanted light of fall.


As the spreading, woodland plants profiled above establish themselves, you can add pockets of other special natives like trilliums, jack-in-the-pulpits, mayapples, bloodroot, and ferns.  The result is magical.
