Blue Diddley Chaste Tree
Blue Diddley Chaste Tree (Vitex agnus-castus 'SMVACBD')
Blue Diddley Chaste Tree (Vitex agnus-castus 'SMVACBD'), also known as dwarf vitex, is a compact, deciduous shrub prized for its aromatic foliage and vivid spikes of lavender-blue flowers. A smaller version of the classic chaste tree, this variety delivers the same pollinator-attracting blooms in a tidy, landscape-friendly form ideal for smaller spaces.
Distinctive Features
Reaching just 3 to 6 feet tall and wide, Blue Diddley forms a neat, rounded habit with finely textured, gray-green foliage that emits a spicy fragrance when brushed. From early to mid-summer, upright spikes of soft blue flowers emerge, drawing in bees, butterflies, and hummingbirds. This long-blooming shrub provides color, fragrance, and texture with minimal care.
