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.

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. Developed by Oregon State University with the USDA. Patent #25,300. USDA zones 7-9.

Size: 4" Pot


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.

Heathy plant

Nicely packaged

Received the little plants (plantlets?) very well packaged. So plants arrived in great shape. Had prepared the ground ahead of time, so planted them the day after they arrived. Watered in, and now it is raining, so they should establish well. We ll see how they grow over the next year, and in a couple of years how they taste.

Blackberry plants in the fall

I ordered blackberry plants and Raintree got them to me the next day. Even though it freezes at night I cover them and the are doing just fine. Thank you!
