Perennial in USDA zones 7 - 11; grown as an annual in cold winter climates. Rose-violet to lavender blooms at the tips of tall, strong stems create a light, airy wave of color through the flower bed. Very attractive to butterflies, bees and hummingbirds. Reseeds itself readily — a welcome volunteer! Also called tall or purpletop verbena, purpletop vervain and South American Verbena. Deer resistant.
