Plant Profile: Physocarpus opulifolius

This plant thrives in full sunlight but benefits from some shade, particularly in its southernmost habitats. If necessary, pruning should be done right after flowering and no later than mid-August. In winter, it can be cut back to the ground to promote new growth. You can often find it flourishing on rocky hillsides, stream banks, and in damp thickets.

The plant's peeling bark is most striking in winter when the leaves are absent. Its common name is derived from the nine distinct layers of bark it possesses.

Transplanting this species is straightforward.

Cultivars with purple leaves tend to lose their vibrant color when exposed to prolonged sunlight throughout the day.

In terms of habitat, Var. intermedius is typically found on limestone river bluffs, in mesic hammocks, along stream banks, and on rock outcrops. Var. opulifolius is commonly located in stream banks, riverside thickets, scour prairies, rock outcrops, cliffs, fens, and seepage swamps, particularly in areas with mafic or calcareous rocks.
