Blue Vervain
Verbena Hastata
The small, tubular, blue-violet flowers of Blue Vervain bloom from the bottom up in July’s heat. The numerous crowning spikes of blossoms give a candelabra-like appearance to this graceful, widely-distributed plant.
As the alternative name Swamp Verbena suggests, this Vervain likes wet, even soggy, conditions; but also will grow in medium soils. Full sun to partial sun are its preferred light conditions.
