Commonly called Purpletop Vervain, this is one of the best flowering perennials for attracting butterflies, and in particular the Tiger Swallowtail. Easily grown from Verbena seeds, this is a long-blooming, drought-tolerant plant that is extremely easy to grow.
The rosy-violet flowers are tiny and extremely profuse. The flower clusters are held on long strong stems. This variety has been called Verbena on a stick! It is also referred to as Brazilian Verbena and Upright Verbena.
