Blackcap Raspberry (Rubus leucodermis)
If you are looking for a tart and decadent treat to ward off invasive Himalayan blackberry in your yard, look no further than Washington native Blackcap raspberry (Rubus leucodermis)!
This brambly perennial shrub has powder white canes and antioxidant rich berries that turn from red to black as they ripen. Typically, this shrub can grow to be around seven feet tall. However, with regular pruning these plants can also take on a smaller size to accommodate any space.
In conjunction with its stimulating taste and striking color, Blackcap raspberry is a helpful ally in the fight against one of our region’s most persistent and invasive plants, Himalayan blackberry. Armed with protective thorns, Blackcap raspberry also can re-root wherever its canes touch the ground, making it a staunch replacement for Himalayan blackberry that is sure to help protect your outdoor space from the return of any invasives.
