Yellow marsh marigold, Cowslip
Ranunculaceae (Buttercup Family)
A succulent plant with glossy, heart- or kidney-shaped leaves and a thick, hollow, branching stem
with bright, shiny yellow flowers. Yellow marsh-marigold is a mounded perennial,
1-2 ft. tall, with thick stems; broadly heart-shaped leaves; and clusters of large, showy, buttercup-like, yellow flowers.
The flowers of this showy spring plant resemble large buttercups rather than the marigolds. The leaves are sometimes used as potherbs but require several short boilings with changes of water between. They should not be eaten raw. A smaller species, Floating Marsh Marigold (C. natans
), found from Alaska southeastward to northern Minnesota, has small white or pinkish flowers, kidney-shaped leaves, and stems that often float.
