March Perennial of the Month-Celandine Poppy
My neighbor’s two granddaughters used to come around this time every year to sell us Girl Scout Cookies. There would be lots of little-girl giggles and squeals of excitement during the brief visits. They have since grown up, and we miss their cheery visits as much as the cookies. Like “cookie season,” some plants come around every spring to sweeten and brighten your day. You don’t hear “heavy shade tolerant” or “wet soil tolerant” very often in the perennial realm, let alone a showy bloomer on top. Now add “Native” to the list, and you have a very, VERY desirable perennial for many gardeners. Celandine poppy, Stylophorum diphyllum, wears all those badges with honor, and like an adorable cookie-selling Girl Scout, she earns all her badges with charm and a sunny smile.
Growing between 12-18” high, the blue-green tinted, fern-like foliage with silver undersides appears in early spring, then brightens up the shade garden or forest floor with its bright yellow blooms. But it’s not just the blooms that are yellow…the stems exude a yellow sap that was supposedly used by Native Americans for dye and medical purposes. (Keep in mind, if you are pruning to avoid staining.)
Fun to find in the wild near streams and low-laying moist woodland areas on spring walks, Celalndine poppies usually go dormant by mid-summer, especially in dry conditions. Being a reliable reseeder, it will return next spring to your shade or rain garden like a good little Girl Scout with your Thin Mint cookies and that sunny smile.
What I love about this plant;
-It’s NATIVE!
-Tolerates full shade.
-Tolerates wet soils-great for shady rain gardens.
-Brightens up dark corners of the garden.
-Like a Girl Scout, makes friends with the other plants in the garden, especially paring well with Virginia bluebells, (April Perennial of the Month-Virginia bluebells –) bulbs, and other emerging spring perennial favorites.
-Beautiful blue-green foliage with silver undersides.
-Super low-maintenance.
-No major pests or diseases.
What’s not so great;
-Will go dormant early if it dries out.
-Will reseed, which can be a pro or a con. If placed in a shady mixed border, be prepared to deal with the seedlings in places you might not like.
