Native to Mongolia and parts of China and Japan, bluebeard thrives in full sun in its home range of steep hills and dry, infertile soil. 'Arthur Simmonds', is the result of a cross between Caryopteris incana and Caryopteris mongholica.
The original hybrid was raised in plantsman Arthur Simmonds' garden in Surrey, England, in 1933 and belongs to that group of plants known as dieback shrubs. These are soft-wooded shrubs or subshrubs that behave more like herbaceous perennials than like woody shrubs. Their above-ground growth tends to die back, anywhere from a few inches from their tips all the way down to the base of the plant. But the roots remain hardy to zone 5 if planted on a sheltered spot. It is said that 'Arthur Simmonds' is a little more hardier.
