Grey Rock Mountain Ninebark
Physocarpus monogynus 'Grey Rock'
Plant Details:
Plant Type: Shrub
Plant Family: Rosaceae
Plant Description: This handsome deciduous shrub is native to the Rocky Mountains. In the spring, trilobate green leaves appear, followed by pink flower buds that open into clusters of white flowers that are beloved by native pollinators. Fiery orange foliage in the fall and peeling cinnamon-colored bark in the winter help this shrub maintain its attractive and interesting appearance throughout the year.
Maintenance:
Maintenance Type: Shrub - Renewal
Plant Care: Shrub - Renewal (woody multi-stemmed plants that lose their leaves every winter and look best on younger stems, which emerge from the base of the plant): Prune regularly to promote health, provide air circulation, maintain a desirable shape, and to remove dead or damaged branches. Pruning is best done in late winter to early spring for most shrubs. With spring blooming shrubs, prune after the blooms are spent. When pruning, remove 1/3rd of the oldest branches by cutting at the base of the shrub. Monitor for pests, diseases or other ailments on a regular basis.
