Stylophorum diphyllum, commonly called Celandine Poppy, is a very pretty North American Native perennial in form, flower, and foliage. It forms a lovely mound of foliage to 12 inches high and wide of blue-green, oakleaf-like leaves from which rise stems to 18 inches high bearing 4-petaled, bright yellow flowers resembling those of poppies. The flowers come in late spring through early summer, attracting butterflies and beneficial pollinators. The plant stems contain a bright yellow sap used as a dye by the native Americans. Celandine Poppy prefers life on the shady side, found in the wild in moist woodlands and along streambanks. Morning and evening sun are fine, but do avoid direct afternoon sunlight. In optimum conditions, the plant will often self-sow to form a colony. Our gardens have no problems with pests or disease; the deer and rabbits leave them alone. 

Growing 12 to 18 inches tall and a foot wide, the Celandine Poppy is ideal for an accent plant in small garden spaces and containers. Where space allows, it is lovely in groupings or mass plantings in partially to fully shaded woodland settings, especially where the soil is moisture retentive along streambanks and other bodies of water. It is also a perfect filler plant around shrubs and trees in shady borders. It is a fine addition to shade gardens, woodland gardens, butterfly gardens, native gardens, cottage gardens, and yellow theme gardens.

Suggested Spacing:  12 inches for mass plantings 

Celandine Poppy is easy to grow in moist or wet but well-drained soils and partial to full shade. Morning and evening sun are fine, but avoid direct afternoon sunlight. Heavy, dense clay soils should be amended with organic matter to improve drainage. The plant can usually get enough nutrients when growing in a woodland setting; however, it can benefit from a dose of organic plant food late winter to early spring. No pruning is necessary.
