- 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.
- Leaves are oval, silvery-gray and 1-2 in. (2.5-5 cm) long.
- Flowering occurs throughout the year, when small clusters of violet flowers develop at the ends of the branches.
- 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.
