Blue Vervain
Verbena
Vervain
Our noteworthy offerings from this diverse genus feature captivating cool-colored summertime flowers, coarsely toothed hairy foliage and 4-angled stems. Easily grown in average garden soil, they will delight you with months of bloom and a lighthearted presence.
This hearty North American native grows straight, developing a dense, broad crown after a few seasons. The effect is almost candelabra-like, with tiny blue-violet blooms and deep purple bracts opening in an upward-moving whorl along branching flower spikes. The vibrant bicolored glow of the blossoms reflects the deep purple stems and brightens the pointed dark green opposite foliage. For an arresting blend of forms, plant this Vervain with Silphium integrifolium and Sesleria "Greenlee".
