Vitex: Chaste tree for a reason

Common names are often poetic or reflective of a plant's practical use. I never thought about it before, but here is the reason that Victoria's favorite, deer resistant, late blooming shrub is also called the Chaste Tree:

"...the shrub's been highly touted for its effectiveness in regulating menstrual cycles and relieving symptoms of PMS (I recently stumbled across a book titled Vitex: The Women's Herb). It also has a positively ancient reputation as a sexual suppressant, one that Athenian women used to keep themselves chaste while in frenzied worship of the Greek goddess of harvests. According to the Roman naturalist Pliny, the celebrants "made their pallets and beds with the leaves thereof to cool the heat of lust."

And it wasn't just the ladies. Southern European monks are said to have brewed libido-busting tea from the shrub's fruit - hence its other common name, monk's pepper (talk about your condiments).

But it's the most innocent of pleasures that have led me to the chaste tree - its performance in the late-summer garden. This woody verbena relative can play a role easily as dynamic as those of Buddleia davidii (butterfly bush), Hibiscus syriacus (rose of Sharon), Campsis radicans (trumpet vine), and Caryopteris x clandonensis (bluemist shrub).

Anything but chaste in appearance, vitex has all the angles, with a multiple-stemmed symmetry enhanced by tapered, five-fingered leaves and jaunty eight-inch flower spikes of the softest lilac blue. It's a shrub that seems always in motion, what with the aerial high jinx of dive-bombing hummingbirds and silver-backed foliage that flickers in the wind. Though vitex is capable of at least ten feet if left unpruned (or better yet, limbed up like a tree), it can also be treated as a perennial and cut back to the ground each spring (like Buddleia, it flowers on new wood).

Chaste tree is a Mediterranean native and, as such, prefers life sunny and well-drained. Though it's drought tolerant once established, it will grow faster with supplemental summer water. Still, given the modesty of these cultural requirements, it's surprising the plant isn't more of a staple in the low-maintenance garden (and that its cultivars are so difficult to find). My best guess is that the chaste tree is a hard sell in spring, when it's more stick than shrub with no sign of green. Even an experienced gardener might mistake it for dead up until June, since it's predictably late to leaf out. Alas, by the time it's really cruising, most gardeners are finished buying shrubs."
