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 vigorous North American native grows upright and develops a dense, broad crown after a few seasons. The effect is almost candelabralike, with tiny blue-violet flowers and purple bracts opening in an upward-moving whorl along branching flower spikes. The vibrant glow of the flowers reflects the deep purple stems and brightens the dark green pointed foliage. For an interesting blend of forms, plant this Vervain with Rodgersias and Helianthus hirsutus.
Blooms July–September.
Size: 4' 0" high x 18" wide.
Hardy to zone 4.
