Thimbleberry Western Thimbleberry
Rubus parviflorus
Rosaceae · broadleaf · native
You recognize Thimbleberry by its enormous maple-like leaves and white crinkled petals in loose clusters appearing on thornless 4-8 foot canes in open forests and meadow margins throughout the Pacific Northwest. The bright red thimble-shaped aggregated fruit appears in mid-summer and is prized by birds, bears, and humans alike. The canes are naked and hairless, distinguishing this species from prickly brambles.
Thimbleberry adapts from full sun to deep shade but fruits better with some light. Plant in rich, well-drained soils with consistent moisture; the shallow root system dislikes drought. Do not remove old canes unless damaged; they fruit in the second year. Monitor for multiple fungal diseases and manage with good cultural practices. This excellent wildlife plant enriches native gardens and riparian plantings.
