Stylophorum diphyllum

Yellow Wood Poppy is a rhizomatous herbaceous perennial wildflower in the poppy family that is native to Eastern USA in moist open deciduous forests, along streams and ravines. It is not native to NC but should be able to be grown in the mountains and Piedmont areas.  The scientific name is derived from its form, phoros relates to its long columnar style, while stylos translates to style.  

In spring to early summer they produce bright yellow 4-petal flowers that are followed by a bristly blue-green pod that hangs below the leaves. Although typically yellow, the flowers can contain a hint of orange.  Deadhead after blooming to stimulate additional blooms.

Although a self-seeder, it is not an aggressive plant and additional plants can be easily removed by pulling them up.

The plants need moist humus-rich soils in partial to full shade.  When mature, they are somewhat drought tolerant, however, they will go dormant in summer if allowed to dry out. Use this plant in woodland settings, shady native plant or naturalized areas or along streams and ponds.  

Its survival in the wild is said to be threatened in some locations by garlic mustard, an invasive plant that can destroy the habitat of this plant.

Insects, Diseases, and Other Plant Problems:  Other than minor issues with slugs, insects and disease is not an issue.

Its self-seeding can become an issue when attempting to control the plants spread.  

The sap from the fruits were used as a dye by Native Americans.  Contact with the sap can stain your skin.
