The Vitex 'Shoal Creek' has earned a dominant status among the Vitex agnus-castus cultivars and it has several unique qualities that are responsible for this popularity. This cultivar of Vitex was selected for it vigorous growth habit and large flower spikes and it produces the best blue-purple flowers. Vitex are large multistemmed shrubs that maintain fairly dense, symmetrical and rounded canopies. Vitex also have some spring interest because the new branch growth has a showy purple color that turns red-brown and lastly a pale gray color as the branch matures. Vitex have medium to fine textured leaves that are 3 to 4 inches long with 5 to 7 leaves per stem. Vitex have a gray-green leaf with a lighter silver-gray color underside and in the fall the leaves develop a purple tint. In early summer Vitex begin producing silvery gray buds on the tips of each stem that open to a beautiful display of lavender blue flowers that are extremely fragrant. Each cluster of flowers that the Vitex produces has dense rings of lavender blue flowers and each cluster can range from 8 to 12 inches long. This process continues for several weeks until the clusters, which are relished by butterflies and hummingbirds, completely blanket the entire canopy . The Vitex can tolerate most soil conditions, provided they are well drained, and it will flourish in full sun. This Vitex cultivar is designated as a Texas Superstar Shrub by Texas A&M University. Although currently considered invasive in Central Texas greenbelts, it is not likely to become a problem in drier, rockier Hill Country areas. it's deer-resistant, although bucks will brush their antlers on its branches if the plant is allowed to grow large
