Description
Verbena Hastata Vervain showcases lance-shaped, sharply toothed, green leaves. It has a stiff, upright habit. Vervain produces candelabra-like inflorescences of erect, slender, pencil-like spikes of tiny, tubular, 5-lobed, densely-packed, purplish-blue flowers from July to September. This rough, clump-forming perennial requires full sun and prefers average, medium to wet soil. It is suitable for borders, meadows, and prairies.
