Alphabetical Plant Listing

Stylophorum diphyllum (Celandine Poppy)

Celandine Poppy, Yellow Wood Poppy


Brightening shady areas, Stylophorum diphyllum (Celandine Poppy) is a showy clump-forming perennial boasting charming clusters of brilliant yellow poppy-like flowers, to 2 in. across (5 cm), in early-mid spring. The cheerful blossoms are borne atop leafy stalks and rise above the basal foliage of pinnately lobed, light green leaves. They give way to small pods with interesting long white hairs. A great naturalizer, Celandine Poppy self-seeds readily. If left undisturbed, it will colonize large areas and cover the ground with a sea of yellow. The plant may go dormant and its foliage disappear by late summer if it is not grown in consistently moist soils. A beautiful plant for the shaded, moist garden.

  • Grows up to 12-18 in. tall (30-45 cm) and 10-12 in. wide (25-30 cm).
  • Prefers part shade to full shade in average, medium to wet soils.
  • Excellent choice for woodland gardens, cottage gardens, rain gardens, wildflower gardens. Requires moisture throughout summer, leaves will wither and turn yellow during drought.
  • No serious pest or disease issues.
  • Propagate by seed or division. Divide large rhizomes with many eyes, leaving two eyes in each division.
  • Native to eastern North America.
