Caltha palustrisAlso known as:
yellow marsh marigold,
Caltha palustris is a clumping plant that can form 1 1/2' tall mounds. The leaves are deep-green, glossy, kidney or heart-shaped. The yellow flowers are waxy and resemble over-sized buttercups. This is an overall showy plant.
Yellow marsh marigold is native to low-lying, wet meadows, marshes and water margins. It does well in part shade, and full sun if provided with ample moisture. It is low maintenance and will spread readily under ideal, wet conditions, via rhizomes. Under dryer conditions, these will die back and the plant will remain as a clumped specimen. Bloom times are from April to June. Zones 2-7
Easily propagate by division. Can also be easily propagated from seed. The seed capsules burst open when ripe, scattering the seeds. timing is critical if you are trying to collect them.
Caltha palustris is actually not a marigold (Aster family) at all, but rather a member of the Buttercup family. Like all members of this family, all parts of this plant are toxic if ingested in large quantities. However, with adequate preparation several parts are edible. Young leaves may be double boiled to remove any toxins, and make delicious cooked greens. The young flower buds can be parboiled and pickled as a substitute for capers.
