Physocarpus opulifolius SUMMER WINE (PBR) is a deciduous shrub grown for its deep foliage colour and clean, upright outline rather than showy flowers. The leaves emerge rich wine-purple in spring and hold their dark tone through the season, creating strong contrast in mixed planting. In early summer, small pale flower clusters appear lightly across the plant, adding texture without distracting from the foliage. The shrub develops a narrow, well-structured framework that stays controlled and balanced, making it easier to place than broader ninebark varieties. Reliable, adaptable, and visually consistent, SUMMER WINE works particularly well where bold leaf colour and tidy form are needed to anchor borders or modern planting schemes.
