Parney's cotoneaster is a 6-8 ft. tall and 6-12 ft. wide mounding shrub in the rose family. The leaves are dark green above and beige below. Clusters of small white flowers bloom in spring and become bright red berries in fall and winter. It was introduced from China as an ornamental plant and has escaped cultivation, primarily in the San Francisco Bay area and along the coast of Marin, Sonoma, and Mendocino counties. CalWeedMapper shows its distribution in California outside of cultivation.
Each plant produces thousands of fruits each year, which are distributed by birds, small mammals, flowing water, and human activities.
It is found in disturbed places, especially near residential sites, as well as undisturbed coastal scrub, grassland, and forests.
Why is this plant not included on the invasive plant list?
Parney's cotoneaster was included in the 2016 nursery survey. It was found at 1.2% of nurseries, which makes it not commonly sold enough to be added to the list. It is not as common as other Cotoneasters.
