Thimbleberry
Rubus parviflorus
  
About Thimbleberry (Rubus parviflorus) 37 Nurseries Carry This Plant Thimbleberry (Rubus parviflorus) is a perennial in the Rose family and is related to raspberries and blackberries. Spreading through underground rhizomes, the thornless canes can create a dense stand that is topped by large, maple-like leaves. In the spring, large white flowers bloom above the leaves. A bright red, edible fruit that resembles a raspberry (or a thimble, as the name suggests), ripens in summer.

Bees and other pollinators are attracted to the flowers, and the leaves are a host plant for many different species of butterflies and moths. Birds and other mammals eat the berries.

Thimbleberries grow in partly-shaded forest openings and on moist woodland canyons or slopes. Use Thimbleberry for erosion control on slopes in a forested garden; near shady creeks or streams; or on the north side of a house. Thimbleberry can be used as a native plant substitute for non-native berries in an edible garden or food forest.
