Sow-teat blackberry is a native shrub that produces thorny canes and edible blackberries in summer. It forms dense thickets over time and provides white flowers followed by dark purple fruit. The plant spreads by underground runners and can become quite large if not managed.

In an HOA neighborhood

Sow-teat Blackberry takes more care to keep looking intentional in a front yard. Maintenance level: high. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.
