Columbia Giant Thornless Blackberry
Rubus subg. Rubus Watson 'Columbia Giant'
When we say Columbia Giant, we're not kidding! Enjoy bountiful crops of the largest-ever, thornless blackberries. The mild-flavored fruit is firm and easy to pick, conical in shape, and sweet - with a pleasing touch of tartness and just a hint of raspberry flavor.

Ripens early summer - early July here in the PNW. The plants are trailing and vigorous, and would benefit from trellis support. Expect 10-15 pounds of berries per crown.
