Purpletop Verbena Seeds.
A beautiful perennial flower, Purpletop Verbena (also called Vervain) is quick to become a gardener’s favorite. Long, slender, woody stems sway in the breeze, and are topped by clusters of purple flowers that are irresistible to butterflies and hummingbirds. Purpletop Verbena reaches 3-5 ft. tall, with a long-blooming season (early summer to fall) and low-maintenance qualities (drought tolerant and easy to grow).
