Easy-to- grow fern with delicate, bright green fronds. Form and texture of this fern are unique. Fronds are twice cut into large, rounded leaflets that make the foliage resemble the pea family. Fronds are crowned with golden, fruiting leaflets on wine-colored stems that resemble groups of flowers, hence one of its common names. Tolerates year-round shallow water. Native to swamps, marshes, stream banks, and moist depressions in the ground.
