Delta Blues™ has fragrant, bluish-purple flowers that form on the new growth of the branches. The flowers produce a showy, small red-coloroed fruit. The foliage on V. agnus-castus is highly aromatic, and Delta Blues™ is a more compact form of the species. Adapts to acid or alkaline soils as long as the site is well-drained, salt tolerant. Vitex are large multistemmed shrubs that maintain fairly dense, symmetrical and rounded canopies. It can be limbed up to grow into a small tree over time. Great for use as a large flowering hedge or specimen plant. Attracts butterflies and hummingbirds.
