About

Caryopteris incana, the common bluebeard, is a species of flowering plant in the family Lamiaceae. It is native to central and southeastern China, Taiwan, Korea, and western Kyushu, Japan. An aromatic perennial subshrub reaching 50 cm (20 in), it is typically found at elevations from 100 to 800 m (300 to 2,600 ft). There are a number of cultivars, with 'Jason', which reaches 80 cm (30 in), being readily available from commercial suppliers. With Caryopteris mongholica it is a parent of the hybrid garden plant Caryopteris × clandonensis, the blue-mist shrub.
