The small bell-shaped pale lemon-yellow flowers of
Dirca palustris are in bloom today. The flowers with their long bright yellow stamens bloom in clusters along the branches before the leaves emerge.
What a lovely surprise for a late winter day.

Dirca palustris is an early blooming deciduous native shrub. It can be found in rich, moist, neutral soil in woodlands scattered (meaning uncommon) over much of eastern North America. The small yellow flowers first appear in late winter and continue into early spring just in time for small bees to stop by for nectar and pollen.
If
Lindera benzoin (Spicebush) is happy in your garden conditions, then, so will Leatherwood. They may be found near one another in woodlands and forest settings. They also share similar characteristics: bloom time, yellow flower color, leaf shape, blooming in deep shade, red fruit and lovely yellow fall leaf color. They're both blooming in my garden right now and make those shady spots pop with their yellow flowers.
In the annals of underused/under appreciated native shrubs Leatherwood could be the poster child. I love this accurate quote from Dirr's:
"A great restrained, dapper, shade-loving shrub that simply cannot find its way out of the shadows into commerce."
It's always a shock to me that many of our lovely native perennials and shrubs receive relatively little attention in the nursery and landscape trade despite their many attractive features.
Dirca palustris should be at every Independent Garden Center. Researchers suggests that its slow growth and the uncertainty about how well it might be be produced asexually has slowed industry interest.
I think that we wildflower/native plant aficionados could make a difference for these orphaned natives. We can start with requesting natives at our garden centers and we can stop purchasing the same old-same old exotics that don't add wildlife value to our gardens.
We must be the squeaky wheel for natives!
Where did I get mine? It was a gift from a good friend. I was thrilled to get it and planted it in a shady spot (built up over time from leaf mold) that has good soil that doesn't turn to concrete in the heat of the summer. It's underplanted with
Phacelia bipinnatifida and
Hydrophyllum macropyllum. Consider planting Trout lilies, Virginia bluebells and other moisture and shade tolerant natives under the Leatherwood.
Gardeners don't dispair! You, too, can find this delightful little beauty for your garden. Local gardeners can find in at
Growild Nursery. It's also available online from
Prairie Moon Nursery and
Mail Order Natives (good reviews).

Welcome to
Wildflower Wednesday and thank you for stopping by to see/meet
Dirca palustris, our Wildflower Wednesday star. In a shady garden like mine, the shrub layer is just as significant to wildlife as the herbaceous level, so, shrubs and even understory trees are going to be an occasional star. Leatherwood is a sweet native shrub that has been under-appreciated for too long. I hope that giving it the attention it deserves will help. Thanks also, for joining in and if you are new to Wildflower Wednesday, it's about sharing and celebrating wildflowers from all over this great big, beautiful world. Join us on the fourth Wednesday of each month. Remember, it doesn't matter if your wildflower is in bloom or not and, it doesn't matter if we all share the same plants. Please leave a comment when you add your url to Mr Linky.

The last of the summer Phlox and the first of the woodland ex-asters, both stalwart wildflowers at Clay and Limestone. I can't imagine gardening without either of them. This may be the only photo I have of an ex-aster without pollinators!
