Description
Physocarpus opulifolius, commonly known as the Blasenspiere or Bluehende Blasenspiere, is a hardy ornamental shrub native to North America. It is prized in small gardens for its foliage, which remains dark red to bronze throughout the growing season. In June, the plant produces small white to pale pink flower clusters that attract bees and other insects. The shrub is frost‑hardy, tolerant of pruning and drought, making it suitable for low‑maintenance hedges.
Care instructions
Water only regularly during the first growing season; thereafter, rainwater is usually sufficient. For cultivars with colored foliage, prune after flowering in June to preserve the vibrant leaf color. Every three to four years, remove the oldest basal stems to keep the plant vigorous. A compost application in early spring (around mid‑March, week 11) supplies nutrients for the season.
