Looking for a flowering perennial that thrives in moist soil? Marsh marigold (Caltha palustris), a member of the buttercup family of flowers, prefers wet areas such as in a water garden, at the edge of a pond or in a wetland area. Ranging in height from 6 to 24 inches, marsh marigold produces yellow blooms from early spring through mid-summer. Blooms are about 1 inch across and leaves are up to 4 inches across.

Propagating marsh marigolds
Choose a sunny, wet location to plant marsh marigold, which is a self-seeding plant. Plant from seed in early summer or by dividing the root ball in early spring or late summer. Extract seeds in the fall from the seed pod or allow the seed pod to drop and self-seed. Newly set plants typically bloom the second year. When setting out multiple plants, space about 12 inches apart.
