The Shoal Creek Chaste Tree (Vitex agnus-castus 'Shoal Creek') is a fast-growing, deciduous shrub or small tree admired for its fragrant, spiky clusters of lavender-blue flowers that bloom from summer into early fall. Its gray-green, aromatic foliage adds texture and a Mediterranean feel to the landscape. Growing 10–15 feet tall and wide, it has a graceful, vase-like shape and attracts pollinators like bees and butterflies. Drought-tolerant and deer-resistant, this low-maintenance plant thrives in full sun and well-drained soil. Shoal Creek is an improved variety known for its vigorous growth, larger blooms, and resistance to powdery mildew.
