Vitex First Editions Delta Blues

Vitex First Editions® Delta Blues™ is a refined, compact cultivar of the traditional Chaste Tree, specifically selected for its intermediate size and remarkably deep flower color. Forming a neat, rounded-to-upright multi-stemmed deciduous shrub, Delta Blues features attractive, palmately compound dark green leaves that release a pleasant, sage-like aroma when crushed. From early summer through early autumn, the plant produces abundant six to eight-inch upright flower spikes filled with rich, dark blue-purple blossoms. Unlike the lighter, paler lavender shades of the straight species, Delta Blues delivers a far more intense, saturated violet-blue floral display while holding a much tidier growth habit. In residential and commercial landscape design, Delta Blues™ matures to an easily managed height and spread of eight to ten feet, solving the space issues often posed by full-sized twenty-foot Vitex varieties. Its compact stature makes it an ideal fit as a dramatic focal point in small gardens, a informal privacy hedge, an accent along property borders, or a patio container plant. The fragrant blue-purple flower spikes act as an incredible magnet for pollinators, drawing in honeybees, native bees, butterflies, and hummingbirds continuously throughout the hottest months of summer.
