Estimated Native Range
Summary
Stylophorum diphyllum, commonly known as Celandine Poppy, is a deciduous perennial herb native to rich, moist deciduous forests, particularly those with calcareous soils, in the Eastern United States and Ontario. It typically grows to about 1.5 feet (0.46 m) tall, spreading through underground rhizomes. The plant is notable for its yellow-orange latex, which can stain. Celandine Poppy is recognized for its vibrant deep yellow flowers that bloom in the spring, creating a striking display against the forest floor. Each flower consists of 4 yellow petals, two ephemeral sepals, numerous yellow-orange stamens, and a single prominent stigma, appearing singly or in small clusters from early spring to early summer. The foliage is blue-green, deeply lobed, and provides a lush backdrop for the flowers. After pollination, bristly blue-green seed pods form, hanging beneath the leaves.
The Celandine Poppy is valued for its showy flowers and ability to thrive in shaded garden areas, making it an excellent choice for woodland gardens, shade gardens, and naturalized areas. It is relatively easy to maintain, long-lived, and can self-seed in favorable conditions. Gardeners should plant it in moist, high-humus soil, and provide part to full shade with medium to high water availability. Soil should have slow to medium drainage. While it is generally free from serious pests and diseases, it can be susceptible to root rot in overly wet conditions. Propagation can be achieved by sowing seeds or dividing clumps in the spring. Dividing should be done in the morning on a cloudy and mild day to reduce transplant shock.CC BY-SA 4.0
