The verbena is a valuable ornamental commonly used in hanging baskets and as a bedding plant. The pink, peach, red, white or purple flowers are star-shaped and grow in clusters. The plants grow quickly and respond well to trimming.

Trailing verbena, blue vervain (verbena hastata), rigid verbena and moss verbena have all become naturalized in some warmer parts of the US. Though it is semi-hardy, verbena is mostly treated as an annual plant.
Verbenas need full sun and moist well-drained soil, and must have good air circulation. Trim off the finished flowers to encourage reblooming, and control for spider mites if necessary.
Varieties include Aztec Red, a spreading type with rich tomato-red blossoms; Summer Snow with pure white flowers; and Peaches and Cream with flowers of peachy orange and creamy white. Quartz Purple and Quartz Silver are upright growers and compact at only 8 inches high by 8 inches wide.
