The 'Shoal Creek' Chaste Tree (Vitex agnus-castus) is a fast-growing, multi-trunked, deciduous ornamental shrub or small tree, reaching 10 to 20 feet in height and width. Renowned for its large, fragrant, lavender-blue flower spikes from late spring through summer, it is highly attractive to pollinators, drought-tolerant, and hardy in USDA Zones 6–9.
