Verbena is a genus in the family Verbenaceae, with about 250 species of annual and perennial herbaceous or semi-woody flowering plants, the majority of which are native to the Americas and Asia. They are herbaceous plants, growing up to a metre high with an upright habit, with usually opposite, simple, and in many species hairy leaves and small flowers, with five petals in shades of blue, white, pink, or purple, especially in cultivars. Some species, hybrids and cultivars of verbena are used as ornamental plants. They are drought-resistant, tolerating full to partial sun, and enjoy well-drained, average soils.
