Verbena hastata – goes by many common names, but is most frequently known as Blue Vervain. Vervain is a member of the mint family, and is considered a common weed throughout the northern hemisphere. Vervain is a tall plant with beautiful blue flowers. I am growing some in pots until we can move to our permanent home, unfortunately we don’t have much sun here under our tree canopy, and so I have not enjoyed any flowers this summer.
