Cultivars not in the Arboretum include 'Shirley's compact' and 'Merlot', the latter a Mark Griffith of Georgia find. While we don't have one in the collection, I have seen a number of variegated clones in a couple of collections and they need dissemination. This plant appreciates a loose, organic soil and plenty of bark mulch. Responds to fertilizer. All pruning should be after bloom as flowers are produced on old wood.
Propagation is easy.
Suckering plants can easily be divided.
