Botanical Name:
Vitex agnus-castus var. latifolia
VY-teks ag-nus-KAS-tus variety lat-ih-FOE-lee-ah
Common Name: Chaste tree
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.

Excellent flower in mid to late summer. Attractive to a variety of pollinators and pairs well with Buddleia and Zinnia in a medium space. Certainly can also stand alone in a large garden as a focal point.

Vitex is completely hardy in my Louisville, Kentucky garden, but I would describe it as a small tree, about 15 feet tall and wide. People always ask what it is... it's pretty spectacular in bloom, and reblooms a bit. It's in full sun and needs nothing more than a yearly trimming and limbing up to keep it somewhat under control.
