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. The plants are trailing and vigorous, and would benefit from trellis support.

It is a new introduction from Oregon State University and the USDA, proven to thrive and be hardy in the Pacific Northwest and many other areas of the nation. Ripens early summer - early July here in the PNW. Plant patent 28,369. USDA Zones 6-9.

Size: 4" Pot

QUESTIONS & ANSWERS

Ask a Question
  • Is it full sun or can take part shade or full shade

    For best berries it needs full sun. It is not shade tolerant and cannot live in full shade.

  • How early should I plant these in zone 6?

    As soon as the ground is no longer frozen.

  • Do I need a pollinator with the Columbia Giant blackberry?

    Not at all. As with most blackberries, these are self fertile.

  • best time to plant zone 9

    Springtime.

Showed up as just a stick, which I expected. With in a week it started coming to life and has been growing a little bit everyday. Couldn't ask for more. Also no bugs which is great!

an excellent start

The raspberry arrived in excellent condition. I am planting it inside a 27 gallon storage container(with lots of holes for drainage). It is inside a fence, to keep the deer away from it. It is doing well, going to sleep for the winter.

Plants were quite full of foliage, and very lush

Stabilization in transit might be better, but they weren’t tossed too much

I’ve certainly received worse from others
