Vitex rotundifolia is a perennial shrub with a woody stem that can sprawl more than 60 ft. (18 m) across the ground. Plants are up to 2 ft. (0.6 m) tall. Brittle stems tend to break off in high tide and float off and colonize new areas.
Foliage
Leaves are oval, silvery-gray and 1-2 in. (2.5-5 cm) long.
Flowers
Flowering occurs throughout the year, when small clusters of violet flowers develop at the ends of the branches.
Fruit
Fruit are round, 0.25 in. (0.6 cm) in diameter and dark purplish-black when mature.
Ecological Threat
Vitex rotundifolia is native to the Pacific Rim and was introduced into the continental United States in the 1980s as a beach stabilization plant. Plants prefer sandy soils in full sun.
