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.

April GBBD: Native Phlox for Your Garden

‘Emerald Blue’ moss phlox in my garden

In my last post, Your Native Woodland, I explained how to create your own native woodland garden.  Here I am going to profile some of the wonderful members of the genus Phlox, all native to eastern North America and Pennsylvania in particular.

All the plants except smooth and garden phlox are pictured blooming in my garden right now so I am linking to Garden Blogger’s Bloom Day (“GBBD”) hosted by May Dreams Gardens (link available on April 15) where gardeners from all over the world publish photos of what’s blooming in their gardens.

‘Sherwood Purple’ creeping phlox in my woodland

Phlox are very satisfying native plants to add to all areas of your garden.  They are easy to grow and spread rapidly but not aggressively.  All species that I am profiling are fragrant, some amazingly so, and attract butterflies and hummingbirds.  They are also disease-free except garden phlox, which gets powdery mildew.  And, most importantly, they have copious amounts of gorgeous flowers in purple, blue, pink, and white.  Did I mention that they are native to Pennsylvania and all of eastern North America?!?  What more could you want.

Wild sweet William ‘Blue Moon’, Phlox divaricata


Wild sweet William is the most fragrant of the phlox described here.  Its heavenly scent perfumes the whole garden when it is in bloom from April to June.  It is 8 to 10″ tall and spreading with semi-wintergreen leaves.  Although I have seen it growing in the wild in full shade, I have better success with it in sun to part shade.  Cut it back after flowering to maintain an attractive habit.  My favorite cultivars are ‘Blue Moon’ (photo above), ‘May Breeze’ with steely white flowers, and ‘Blue Elf’, a compact form.

‘Morris Berd’ smooth phlox, Phlox glabberima

Smooth phlox is a taller clump-forming plant, although the clumps expand rapidly when it is happy.  It is 18 to 24″ tall and grows in full sun to part shade in average to moist soil.  Flowers appear from late spring to early summer, a time when not much else is blooming.  The only smooth phlox I have ever seen for sale is ‘Morris Berd’ (photo above).  Its velvety pink flowers with silver highlights are breathtaking.


Garden phlox, P. paniculata, left with purple coneflower and ‘Goldsturm’ rudbeckia in my front border in 1993.

I dream of the day that I can plant a field of every cultivar of garden phlox on the market.  The fragrance of the flowers, second only to wild sweet William, the long bloom period, and the colors available make this a very desirable plant.  It grows anywhere in full sun to a good bit of shade (but not full shade).  It reaches 2 to 4′, and I have cultivars blooming from June to October.  My favorites are very early-blooming ‘Blue Paradise’ (photo below), compact ‘Pixie Miracle Grace’, pure white ‘David’, and ‘David’s Lavender’ with huge flower heads.  Unfortunately, I have failed to photograph these plants in past years, but I hope to remedy that this summer.

‘Blue Paradise’ garden phlox

I get questions all the time about powdery mildew on phlox.  The only phlox that gets powdery mildew in my garden is garden phlox.  The best way to avoid this is to buy mildew resistant varieties but in bad years even these cultivars get mildew.  You can also prevent mildew organically by spraying the leaves with a baking soda and oil formula before mildew strikes.  However, my approach is to ignore it because it doesn’t hurt the plants, it just looks ugly some years.  Focus on the flowers instead and plant plants in front of the phlox that hide the leaves.  Your garden does not have to look perfect.


Creeping phlox ‘Blue Ridge’, P. stolonifera, in my woodland.

If I had to pick one phlox that is my favorite, it would be creeping phlox (not to be confused with P. subulata whose correct common name is moss phlox not creeping phlox).  It has beautiful and plentiful fragrant flowers attractive to butterflies like all the native phlox here.  But in addition, it grows in full, dry shade and makes an excellent 3 to 6″ mat-like groundcover that remains green through winter.  It flowers from March to May.  My favorite cultivars are ‘Sherwood Purple’ (photo at the beginning), which is the most vigorous, ‘Blue Ridge’ (photo above), ‘Home Fires’ (photo below), and ‘Pink Ridge’, which is a slightly different pink and blooms later than ‘Home Fires’.

‘Home Fires’ creeping phlox


‘Emerald Blue’ moss phlox, P. subulata, in my garden


For abundance of flowers, you can’t beat moss phlox: you can’t even see the leaves when it is in bloom in April and May.  It grows in full sun to part shade and forms a wintergreen mat that solidly blocks out weeds.  The needle-like leaves provide an attractive texture year round.  A great plant for dry sites with thin soil because it has a shallow root system and likes to be well-drained.  An annual shearing is recommended although I don’t do this.

‘Amazing Grace’ moss phlox

A lot of breeding has been done with moss phlox to produce a plethora of beautiful flower colors.  They are all good plants, and I don’t have a favorite, but I like ‘Emerald Blue’ (photo at beginning and above), pink ‘Fort Hill’, white with a red eye ‘Amazing Grace’ (photo above), and ‘Purple Beauty’ (photo below).

‘Purple Beauty’ moss phlox

You can’t go wrong when you add any of these wonderful native phlox to your garden.  Enjoy the flowers!
