Verbena hastata - Blue Vervain

  • Blue Vervain's upright flower spikes offer a contrast to other flower forms in any perennial garden or prairie setting.  Small, tubular, blue-violet flowers bloom from bottom to top and produce large quantities of nectar for visiting insects. It prefers moist soils compared to its sister Hoary Vervain, and will do well in wetter spots in the garden, stream banks, and pond edges. Low areas that offer more moisture holding capacities are preffered but Verbenna hastata can tolerate Medium moisture soils as well.
