Rubus subg. Rubus watson 'Columbia Star'

Columbia Star, released in 2014, is a vigorous, thornless, trailing blackberry. It has superior flavor, large firm berries and is very consistently productive. The flavor is rated as good or better than Marionberry, which is 20% of Columbia Star's parentage. It ripens early mid-season; mid-July in Oregon's Willamette Valley. Developed by Oregon State University with the USDA. Patent #25,300.

It is somewhat hardier than a Marionberry; hardy to below 10 F. Its shorter canes end at 6 feet, and coupled with its thornless structure, it's particularly easy to manage in the home landscape. 

Cold Hardy to USDA Zone: 7

Mature Height: to 6'

Sun: Full Sun 

Ripening Time: Midseason

Pollination: Self-Fruitful

QUESTIONS & ANSWERS

Ask a Question

  • Another person asked the question regarding temperatures for this Blackberry. If it was up against a house and mulched heavy could it survive a bit lower than the 0° temperature? I purchased this as a possible extra polinator for another type of thornless Blackberry. The tag on the other said it waa "self fertile" & did not need another pollinator --but having another one was good. But now I wonder ...because I can have variable Winters in NYS. Could I plant it in my glass Greenhouse? It may get cold but it's still warmer than the outside temperature too

    Columbia Star is hardy to zone 7. As a floricane bearing berry the canes and roots will both have to survive the winter to get fruit. As long as they don't get below 0 degree you should be fine.

  • Would an elevation of 3,000 with a plethora of snow work for this berry?

    This berry is hardy to zone 7, which is 0 to 10 degrees. If your area gets below 0 degrees it will not survive.

My favorite blackberry

A little bit slow to get started in year 1, but extremely vigorous in year 2 and produced some of the largest, sweetest, and most flavorful blackberries I’ve ever had. If I could only grow one blackberry, this would be it.
