Bring bold, season-long color to your landscape with Physocarpus opulifolius 'Summer Wine®' (Ninebark 'Summer Wine®'). This deciduous ninebark forms an arching, multi-stemmed shrub with finely textured, wine-purple foliage that reads as deep burgundy in the garden. In late spring to early summer, rounded clusters of small flowers open pinkish to whitish, standing out clearly against the dark leaves.
At maturity, expect a substantial foundation or border shrub: your plant typically reaches about 60-96 inches tall, with a similar spread. After leaf drop, the exfoliating, peeling bark becomes a standout feature, adding layered texture and winter interest.
Give it a site in full sun for the richest foliage color. It tolerates a range of soils and is adaptable once established; provide regular watering during the first growing season, then water during extended dry periods. On slopes or difficult areas, its sturdy root system and spreading habit make it a useful choice where you want dependable coverage and help holding soil in place.
For maintenance, you can keep the natural arching form with minimal pruning. If shaping is needed, prune right after flowering, since blooms form on older wood. You can also remove a few older stems at the base to refresh the shrub and encourage vigorous new growth. Space plants with airflow in mind and avoid overhead irrigation late in the day to help keep foliage looking its best.
