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 sun conditions.
