This easy-to-grow perennial, native from Virginia to Florida and west to Colorado and Mexico, flowers prolifically throughout the growing season. Its clean, dense foliage and trailing habit make it an excellent choice for edging the flower border or for growing in pots and hanging baskets. The flowers also attract butterflies. In colder climates this species can be grown as an annual. "Rose-colored Vervain" was first documented in American gardens by 1822.
