Stylophorum diphyllum, celandine poppy or wood poppy is a beautiful native woodland plant with large, bright yellow flowers from late spring into early summer, followed by fuzzy capsules. It is among the first plants to emerge in the spring and soon enough it develops the blue-green foliage that resembles the greater celandine (Chelidonium majus) hence the common name. It thrives in any part-shaded location in rich, moist or not so moist soil. In locations with too much sun the foliage will get damaged in the summer and it may become dormant; so best to grow it in part-shade. Remove the capsules if you don’t want it to self-seed and to encourage more flowers.
