Vitex agnus-castus (Chaste Tree, Vitex, Monk's Pepper)
Chastetree is a fast-growing, small tree or large shrub native to southern Europe and western Asia. The sage-scented gray-green leaves of Chastetree are shaped liked a hand, or palmate, and were once believed to have sedative effects. The flower is fragrant, lavender blooms upwardly-pointing, placed in terminal panicles and quite attractive to butterflies and bees. The tree is often planted where honey is marketed to promote excellent honey production. Blooms in the summertime. Chastetree likes sunny location with well-drained soil. It thrives in heat and blooms on new growth from the current season, so it can be pruned in spring if need be. In warm regions, it can be shaped into a small, single or multi-trunked tree. In cooler zones, chastetree grows as a modest-sized perennial shrub because it gets knocked back by extreme cold. Vitex agnus-castus will self-sow and can be invasive. It is advisable to cut back spent flowers in areas where seedlings can be problematic. Chastetree is used effectively in the mixed shrubbery border or as a specimen.
