Lance-leaved Arrowood is a native perennial typically found in marshes and swamps along the coast from Virginia south to Florida and west to Texas. It grows in both freshwater and brackish tidal marshes. The roots are rhizomes and need to be submerged in water. The long lance-shaped leaves and distinctive 3-petaled flowers make this an attractive plant for water gardens. It should not be allowed to dry out.
