Chaste tree Vitex agnus-castus var. latifolia Photo/Illustration: Bill Johnson 1 2 3 4 5 6 7 8 9 10 11 Chaste tree (Vitex agnus-castus var. latifolia) VY-teks ag-nus-KAS-tus variety lat-ih-FOE-lee-ah Genus: Vitex Chaste tree is a southern favorite beginning to gain favor across the country. Whether left to grow as a large, multistemmed shrub or cut back annually for a more compact look, this selection is a winner. Fine, lacy leaves are glossy and green. Bright blue flower panicles begin to form in early summer and continue through the heat of the season and into fall. This is a reasonably cold-hardy, deer-resistant woody plant, and while V. agnus-castus is typically considered a Zone 7 plant, the variety latifolia can be grown in Zone 6 and even in southern areas of Zone 5. Noteworthy Characteristics: Apparently, the ancient Greeks used an extract of this plant to “calm the male inner fire.” We're not sure how to put that to use in the garden. Care: These plants are happiest in full sun and well-drained soil. Propagation: From cuttings or by seed. Problems: Leaf spot, root rot, or scale insects. Overview Height 10 ft. to 15 ft.
