With Physocarpus opulifolius 'Calico Kitty™', you get a bold, easy-care ninebark that brings color from spring through fall. New foliage emerges deep copper, then matures to a rich burgundy tone, while clusters of white to soft pink flowers appear in late spring to early summer for a bright contrast.
Plant it in full sun for the strongest color, or give it part shade where summers run hot. It adapts to many soil types as long as drainage is reasonable, and it settles in well with regular watering during establishment. Once established, it handles average conditions and is known for toughness in the landscape.
Expect a mature size around 48-60" tall and roughly 36-48" wide, forming a rounded, multi-stem shrub. If you need to shape it, prune right after flowering so you do not remove next season's buds. Older plants can be rejuvenated by removing a portion of the oldest stems near the base to encourage fresh growth and maintain a dense form.
Use this shrub as a foundation accent, hedge, or anchor in mixed borders where its dark foliage can set off lighter perennials and grasses. Like other ninebarks, it can also offer seasonal interest beyond bloom, including attractive structure and wildlife value in the garden.
