Stylophorum diphyllumAlso known as:
yellow wood poppy
Stylophorum diphyllum is an attractive native poppy. It produces large yellow flowers that may be tinged with orange. These appear singly or in small clusters atop hairy stems to a height of 2 feet. The deeply divided, blue-green foliage will provide an interesting texture to the garden.
Celandine poppy is a lovely bloomer for woodland and shade gardens where its yellow flowers will brighten dark areas. It will grow best in humus-rich, acidic soil that receives ample moisture. This species will go dormant in summer, if allowed to dry out. Stylophorum diphyllum will bloom profusely in spring, and under optimum conditions, will have secondary blooms in late summer to early fall. Though this species self seeds readily, it is less aggressive and easier to control than commercially sold introduced poppy cultivars. Zones 5-6
Propagate from seed in fall or by division in spring.
The yellow sap that exudes from the stems was used as a dye by Native Americans, and can stain skin and clothing.
