Vervain Seeds - Herbal Plant for Home Gardens

Vervain, botanically known as Verbena bonariensis, is a tall, airy perennial plant valued for its slender stems and clustered flower heads. It develops an open, upright growth habit with minimal foliage and produces small purple flowers held above the stems during the growing season. This plant adapts well to warm and temperate climates and performs best in full sun with well-drained soil. Vervain is commonly used in borders, garden beds, and naturalized planting, where it establishes from seeds and can self-seed under suitable conditions.
