Ornamental Verbena
Tall Verbena, or Brazilian vervain (Verbena bonariensis), is a rapid-growing tender perennial that rises dramatically from a low basal mound of dark green, serrate leaves to reach 24-48 inches tall, crowned with showy clusters of tiny rose-violet flowers that bloom from June through frost. Hardy in zones 7-11, it thrives in full sun with moderate water and minimal maintenance, making it surprisingly easy to grow for such an elegant performer. The wiry, branching stems create an airy, see-through quality in the garden, and the flowers are irresistible to hummingbirds, butterflies, and other pollinators.

Rising from a compact 1-foot basal clump, Tall Verbena sends up slender, 4-angled stems that can stretch to 3.5 feet in height, bearing 2-inch flower clusters of rose-violet blooms from mid-summer straight through frost. The plant's rapid growth and low maintenance make it both forgiving and rewarding, while its transparent branching habit allows you to layer it in front of other plants without blocking the view. Hummingbirds and butterflies flock to the tiny clustered flowers, transforming the garden into a wildlife hub.
Tall Verbena is grown as an ornamental flowering plant, valued in garden beds and borders for its long bloom season, airy vertical structure, and ability to attract pollinators. In warmer zones where it persists as a true perennial, gardeners often let it self-seed freely to create drifts of color year after year.
Start seed indoors 6-8 weeks before your last frost date for earlier bloom. Sow seeds on the soil surface or press lightly into moist seed-starting mix, as light aids germination. Keep the soil evenly moist and warm until seedlings emerge.
Transplant seedlings or purchased plants outdoors after the last frost date has passed. Space plants 18-36 inches apart to allow room for their mature width.
Seed may be sown directly in the garden after the last frost date.
Pruning is optional and based on preference. Deadheading spent flower clusters will tidy the plant's appearance and may encourage continued blooming, though allowing flowers to mature will support self-seeding in areas where the plant overwinters.
