Malvaceae (Mallow Family)
A coarse, hairy perennial,
Virginia fen-rose or seashore mallow is much-branched and angular in habit. A large plant with pink, terminal or axillary,
stalked flowers with yellow stamens. It grows 3-5 ft. tall and spreads to 4 ft. in width. Its leaves are triangular-ovate with triangular lobes at the base. The hibiscus-like flowers are light pink and 3 in. across with a central column of yellow stamens.
This Mallow is especially abundant in southern Louisiana. It is distinguished from Hibiscus
by the flat ring of fruit
segments. K. altheaeifolia
, found on east coast of Texas, is recognized by some botanists as separate species; others regard it as a variety of K. virginica
