This spring I planted three rhizomes, one each of Cascade, Centennial and Chinook. It took longer than expected to get my first shoot from each rhizome, and I never got a second shoot from any of them. The Cascade and Chinook have both grown to the top of my garage eave (10'). The top of the shoots started to hang down, so after awhile I started to train them up another string. They both have cones, although not many. The Centennial seems to have stalled out a little better than half way up, and even though it has side shoots, I have yet to see any developing cones. It does get some shade from a lilac tree close by, which might explain why the other two are doing better. I've been told not to expect much of anything the first year, so I'm trying not to get my hopes up.
