Vitex 'Montrose Purple', a cultivar propagated by Treesearch Farms of Houston, is absolutely spectacular this spring. The tree is planted at one end of the daylily bed, on the street side of the house, facing north. Compared to the standard Vitex agnus-castus, the spires on this variety are not only a deeper, richer color but far fuller and more lush. It may just be my favorite small tree.
I like vitex a lot but I just have too much shade in my garden for them to really shine. I'll enjoy yours vicariously instead.

Annie & Gail, the difference in blooms between this Montrose Purple & the species really surprised me. (It can't just be because this one has been in the same spot since it left the container, LOL.)
