Trailing Blackberry, also known as Pacific Blackberry, Pacific Dewberry, California Blackberry and California Dewberry (Rubus Ursinus) is an evergreen perennial viney shrub in the Rose Family (Rosaceae). It’s native to western North America, blooms May-Jun and grows climbing 1-5 ft. It’s commonly found in forests and savannas; likes moist soils and full shade to partial sun exposure.
Trailing Blackberry can climb up and pull down on small planted trees and shrubs. Berries are edible and a good food source for wildlife. Although Blackberry plants look alike, Armenian Blackberry [Himalayan Blackberry] looks like Trailing Blackberry only when plant is young and growing in shade. Trailing Blackberry is more similar to Black Raspberry [Blackcap] because of the white colored stems and light green leaves. Black Raspberry [Blackcap] however grows up and weight pulls it down, unlike climbing Trailing Blackberry.
