Culture
Winter hardy to USDA Zones 8-10 (perhaps protected locations in Zone 7) in consistently moist soils in full sun to part shade. Best in light shade. Reportedly performs well in sun-dappled conditions under large trees. Will survive occasional temperature drops into the low teens in winter but will lose some lower leaves.

Elliptic leaves have marginal teeth near the terminal end. Long racemes of fragrant white flowers with a cinnamon-like aroma bloom from the stem tips between June and August.
Genus name comes from the Greek klethra the name for alder of which the leaves resemble.
