Plant Sale 2025 — Stylophrum diphyllum

Stylophrum diphyllum, commonly known as Wood or Celandine Poppy, adds a spot of bright yellow to a woodland garden from March to May. If given enough moisture, it may re-bloom throughout the summer. If it dries up during the hot summer days, it will reappear come spring of the following year.
The bright yellow 1¼-2¼” flowers look like buttercups on steroids. In addition to some really great blooms Stylophrum diphyllum also has wonderful foliage and seed pods. The leaves are a bluish green and deeply divided. The green plump hairy pods explode throwing seeds away from the parent plant.
Stylophrum diphyllum will self-seed readily when happy. The individual plants are 1 – 1 ½ feet tall and wide. Moist woodland dappled shade is preferred however it will tolerate quite a bit of shade.
PLEASE NOTE: Greater Celandine (Chelidonium majus), a non-native European/Asian poppy can be confused with our native wood poppy but has smaller flowers and seeds pods that are long, thin and hairless.
