Dry forests, usually sandy or rocky, with aspen, birch, oak, or conifers, especially along borders (e.g., at shores, fields, roads, and clearings); thriving after some disturbance such as fire; old dunes, sandy bluffs, railroad embankments, thickets, fencerows.
The ovary is occasionally puberulent but usually glabrous; the leaves are sometimes ± densely pubescent beneath (f. hypomalacum Fernald) but usually glabrous or nearly so except on the midrib. The fruit of this genus and the closely related Weigela, often cultivated, is a slender many-seeded 2-valved capsule.
