Stylophorum diphyllum (Michx.) Nutt.
Celandine poppy, Yellow wood poppy
USDA Symbol: stdi3
USDA Native Status: L48 (N), CAN (N)
This 12-14 in. perennial with gray-green, lobed and toothed leaves is known for its large, poppy-like, yellow flowers. The stalks are leafy and the flowers are produced in clusters. A plant with yellow sap and yellow flowers, solitary or in small clusters, atop a stem bearing a pair of deeply lobed leaves; other leaves basal.
This is a fine species to grow in Eastern wildflower gardens, far less aggressive than the introduced European species. The species name, Greek for two-leaved, refers to the pair of opposite leaves below the flower.
Occurs in nature from western Pennsylvania north to Wisconsin and Michigan, south to Arkansas, Tennessee, and southwestern Virginia, with isolated populations in northern Alabama and southern Ontario. Because its range is so limited in that province, it is listed as a Species Endangered by Canadas SARA (Species at Risk Act) and by COSEWIC (Committee on the Status of Endangered Wildlife in Canada).
