Kosteletzkya pentacarpos

Marsh mallow

Kosteletzkya pentacarpos is a native flowering plant found in the southeastern coastal plain. It naturally occurs in brackish to freshwater marshes. It grows best in full sun sites, with moist to wet soils. It can get up to six feet tall in the growing season, but dies back completely in the winter. Leaving dormant stems up until spring provides necessary over-wintering habitat for pollinators. It has bright pink flowers that bloom in the summer and attract hummingbirds, butterflies, and other pollinators. Birds eat the seeds in the fall and winter. Kosteletzkya pentacarpos is great as a specimen plant in a yard or rain garden, or for restoration projects.
