This drought tolerant Mediterranean native absolutely thrives here in the Rogue Valley! Vitex needs consistent heat in order to bloom profusely, and our long hot summers give them exactly what they like. From mid-summer into early fall, Vitex is covered with long spikes of flowers ranging in color from soft lavender to dark blue. The blooms slowly open from the base to the tips, eventually reaching up to 12 inches long and lasting at least 4 to 5 weeks; attracting bees and hummingbirds from far and wide.
Vitex’s fragrant leaves are very attractive in their own right. Their shape is similar to a lace leaf Japanese Maple; and are a lovely shade of soft blue-green. Most varieties are gray-green underneath, but Flip Side features a dark purple reverse – making them truly stunning in a breeze. As an extra bonus, the fragrance helps make this plant quite deer resistant.
One of the fun things about Vitex is that you can grow it into whatever form you like, multi-trunk or single trunk tree, or a large, broad shrub. The straight species, and varieties like Shoal Creek get about 10-15’ tall and wide. Varieties like Flip Side and Delta Blues are smaller – maybe 8-10’ tall and wide at maturity. Vitex bloom on new wood, so they take very well to a severe pruning, even all the way back to the ground if needed. We have also seen them be used successfully in large containers against hot walls and parking lots.
Vitex grow slower with drought conditions and grow fairly rapidly with regular water and richer soil, but will tolerate both conditions well. We have been very impressed with the cold hardiness and drought tolerance of these shrubs as well as their many uses. Vitex are one of the few choices for a small tree or large shrub that thrives in the heat and has lovely blooms late in the season!
