Trailing Blackberry Western Blackberry California Blackberry Dewberry

Trailing blackberry (western blackberry or dewberry) is a procumbent (trailing) native bramble reaching 10-20 feet when spreading across the ground or scrambling over shrubs. You will find it from British Columbia south to northern California and east to central Idaho, particularly common west of the Cascades.

Trailing blackberry prefers full sun on moist to moderately dry, well-drained soil. The plant spreads by layering but is far less aggressive than Himalayan blackberry. Prune back annually to prevent excessive tangling. The berries are delicious, sweet, and edible; they are harvested by hand or by shaking ripe fruit onto tarps.
