Leaves simple, ovate or broad-ovate, and 2-5" long with truncate to subcordate base. Large green and reddish-brown double terminal buds. Leaf scars are raised. Angled buds and stems. Stems have raised lenticels.
A difficult species to use in a functional way. Best for seasonal color and fragrance in the border or as an occasional specimen. Deadheading can promote flowering and prevent alternate bearing. Will get leggy without pruning (prune on a 3-year cycle). Powdery mildew is an increasingly serious problem the further south this is planted in its hardiness zone. Grows better in colder climates.
