Bacopa is an emersed plant. This small sprawling herb is common in fresh and brackish waters. At least three species of bacopa are native to Florida (Wunderlin, 2003). This species, smooth water hyssop, is distinguished by its white flowers, and is distributed throughout the southernmost U.S. (Kartesz, 1999).
Bacopa leaves are succulent and relatively thick. Its leaves are only 1/8 inch wide and 5/8 inch long. Leaves are oblanceolate, and are arranged oppositely on the stem. Flowers are small and white, with 4 or 5 petals.
