Our hot summers allow us to enjoy this Mediterranean native that is drought tolerant and deer resistant. Heat is neccessary for profuse blooms, and profuse it is once it gets going in July and August. The blooms slowly open from the base to the tips eventually reaching up to 12 inches long and last at least 4 to 5 weeks. The color can vary from pale lavender to a darker purple and attract bees and hummingbirds from far and wide. The fragrant leaves are very attractive on their own- they are divided similar to a laceleaf Japanese Maple and are a very pleasant shade of soft blue-green and gray-green underneath. Chaste tree is late to leaf out in the spring, helping it avoid damage from our late spring frosts; but makes a good small shade tree in the heat of summer. 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. We have seen older specimens around the valley that are 10' tall by about 12-15' wide, meaning they are cold hardy once established and can get quite large. However, they can be maintained at 6' tall and wide or trained up as a small shade tree. 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 have lovely blooms late in the season.
