Caryopteris Bunge

Caryopteris is a genus of, depending on genus delimitation, seven or more species, all native in an area that ranges from Central to East Asia. Three species and a hybrid are cultivated as ornamentals in Europe (Wann 2000). Their separation is not always straightforward. Most garden plants exhibit more or less intermediate features and are best referred to as Caryopteris xclandonensis. However, C. incana, one of its putative parents, is also relatively widespread in cultivation (Hoffmann 2006) and should be looked for.

The classification of Caryopteris (and Clerodendrum) has long been controversial. Both were traditionally placed in Verbenaceae but in fact belong with Lamiaceae (more precisely Ajugoideae) (Cantino & al. 1992, 1999; Mabberley 2008).

In its traditional circumscription Caryopteris is paraphyletic (Cantino & al. 1999). The single species (hybrid) here concerned belongs with Caryopteris s.str.
