Chaste Tree

June 25, 2016


I was in Enid, Oklahoma over the weekend where the temperature was a dry 97 degrees.  I saw an ornamental tree (or maybe bush) called a Chaste Vitex.  It was without question one of the most beautiful trees I have ever seen.  A nursery in Enid told me one of these plants would surely thrive in Arkansas but because I haven't seen any growing in the Little Rock area, I was hesitant to invest in one.  Any advice on whether or not this plant would grow here and if so, any particular conditions?



They are blooming all over town.  The Chaste tree or Vitex agnus-castus is a great multi-trunked small tree or large shrub.  It blooms with spikes of purple flowers from June through early August which many people mistake for a large buddleia or butterfly bush.  The largest Vitex I have ever seen in Arkansas is on the state capitol grounds, but they are growing in many locations in the state and should be readily available at area nurseries.  A cold winter can sometimes take its toll in the northern tier in Arkansas, but mid to south should be fine.  They are best in full sun and are loved by bees and butterflies.

I have a fern-like plant growing wild in my garden.  The stalks are rather thick and sturdy, with feathery offshoots.  It developed tiny purple flowers you had to be right up to the plant to see.


AnswerYou actually have two plants growing together.  The wispy plant with ferny leaves is a common weed called dog fennel - Eupatorium capillifolium.  It can grow quite tall and has a white flower.  It can be aggressive, and is better pulled out and destroyed, even though it does have a nice texture.  I think it is growing in a very leggy chaste tree or vitex.  This plant can be grown as a small tree or a large shrub, with compound leaves and a purple flower spike

QuestionThis tree is much-loved by people (and bees) in our Heights neighborhood because of its fragrant leaves and flowers. I tell everyone it’s a lavender tree because of the colored blooms which occur each June; but I have never seen lavender grow on trees! A neighbor tells me it was planted in the 70’s so it has withstood the test of time but the last few years, in late July, the leaves get a brown appearance, shrivel and about half drop off. Can you tell me what the tree is and how I should care for it?


AnswerThe tree is Vitex tree, Vitex agnus-castus commonly called Chaste Tree. From the picture, it looks like your tree would benefit from being thinned a bit at the base, removing some of the excess twigginess. All of the excess canes could be causing some of the decline. The best time to prune is in late February before new growth begins. If the leaves start their decline again this year, bring some samples in to the local county extension office.
