This is a tall Verbena with few narrow leaves, square stems and flat heads of bright purple tiny flowers. A useful plant for providing some height in the border, it can look as though the flower heads are just floating as its stems are quite slender. It’s only just hardy, leaving the old stems on through winter can help protect it in conjunction with a winter mulching. It’s a wonderful magnet to all the pollinators who love it. This Verbena also looks handsome when planted to grow up through tall ornamental grasses where it can be allowed to self-seed.
