This shrub is grown for its powder blue flowers that cover the bush in late summer. The flowers are airy, have an unusual color, and bloom from late summer into fall. Pollinators are also attracted to the blooms. The foliage is mint green and lightly scented. The shrub only grows to 2 to 3 feet tall and wide. It will have a more compact habit if pruned back hard in very early spring. Pruning will also remove any dieback from winter damage.

Caryoptris blooms best in full sun and evenly moist soil but cannot tolerate saturated soil. It does not have any serious disease or pest problems. The Blue Mist Caryopteris can work in foundation plantings or perennial gardens and is striking when massed.
