Blue Vervain aka: Verbena hastata, is a valuable Native Canadian species found in moist meadows, wetlands, roadsides and ditches. It produces a colourful show of tubular blue flowers on spikes from mid July through September. It is both very fast growing and easily grown from seed. While blue vervain is often included in wetland remediation mixes, it also makes a great addition to the formal perennial border. This tall plant grows from 90-120cm (3-4') high, does best in full sun to partial shade and will readily self seed in moist, deep organic soils. Plant with Joe Pye Weed and Swamp Milkweed for a great show!
