white vervain
(Verbena urticifolia)
| Overview | White vervain (Verbena urticifolia), also called nettle-leaf vervain, is an herbaceous forb that occurs in the eastern half of North America including Minnesota. There are two generally recognized varieties. On one, var. leiocarpa, the underside of the leaf is densely short-hairy, the calyx is shorter, and the nutlet is shorter. The range for this variety is almost throughout the range for the species. It intergrades freely with the other variety, var. urticifolia. For this reason,some authors do not acknowledge the existence of the varieties. |
