Pacific blackberry is a vigorous native trailing bramble that produces small, intensely flavorful blackberries beloved by both wildlife and foragers. Plant in a sunny to partly shaded spot with well-draining soil and provide support or defined boundaries, as canes spread readily and can become invasive in garden settings. Prune out old canes after fruiting each year to encourage productive new growth and reduce thorny thicket formation.
