Much of the varied genus of Verbena originates in the Americas, in both open, sunny sites and open woodland. These plants have square stems and bear small flowers in a wide variety of arrangements. The flowers are long-blooming and salverform, each made up of a slender tube that widens abruptly at the end. Verbenas are excellent for annual borders and containers (especially hanging baskets), and some for the mixed herbaceous border.
