Stylophorum diphyllum
CELANDINE POPPY, WOOD POPPY
SKU: 991-10
Stylophorum diphyllum, commonly called the celandine-poppy or woods-poppy, is an herbaceous plant in the poppy family (Papaveraceae). It is native to North America, where it is found in the eastern United States and Ontario. Its typical natural habitat is moist forests over calcareous rock, particularly in ras.
It is cultivated for its bright yellow flowers. The common name is derived from greater celandine (Chelidonium majus), a closely related European plant with similar flowers and leaves.
In spring, the deep yellow flowers of the celandine poppy appear as a brilliant display on the forest floor. The flowers have 4 yellow petals, two soon-falling sepals, many yellow-orange stamens, and a single knobby stigma. They appear singly or in umbels of two to four flowers from early spring to early summer. Plants grow to about 1.5 feet (0.46 m) tall, from underground rhizomes. Leaves are pinnately cut and lobed.
Plants are relatively long lived and readily self-seed under garden conditions.
Stylophorum diphyllum is a conservative species, and is somewhat uncommon throughout its range. Forest clearance is responsible for some of the loss.
Due to its limited distribution in Canada, it is listed under Ontario's Endangered Species Act, 2007, which protects the species and its habitat. One Ontario population of the wood poppy is in a conservation area.
