Chastetree

Vitex negundo (VY-teks neg-UN-doh)

Family: Lamiaceae Non-native Understory (15-40 ft)

Chastetree is a non-native shrub or small tree that does best in hot weather in full sun. It blooms on new wood, so may be pruned to the ground in early spring like a perennial to invigorate growth. It is loosely branched in an open vase shape with interesting foliage. Preference is for full sun and loose, moist, well-drained soil. Flowers appear on 5-8 inch panicles in mid to late summer. Deadhead to encourage more blooms. It is native habitat, it can be found growing in wastelands of the Himalayas and mixed thickets on mountain slopes with elevations from 600 to 6500 feet. Growing to heights of up to 15', it can grow taller in areas where warm winters are experienced. The young stems are utilized in making baskets and when weaved with other materials can be used from construction. Grows in zones 6 through 9, however, it is not winter hardy in zone 6. It may suffer from dieback or may die to the ground in harsher winters. Planting in a sheltered location is important in this zone where it can be grown as a 3-5' perennial. Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Leaf spot and root rot occasionally affect stressed plants. It may suffer from frost damage during cold winters.
