I have some cascade berry plants to give away. These are Mason family "heirlooms." My grandparents grew cascade berries, which are a close relative to marionberries. I am pretty sure they are a cross between a blackberry and a loganberry, but I've never been able to get an exact peg on that. They are tart berries, but make deadly pies and jams.
My parents' took canes from my grandparents' place in Ladysmith to Victoria where they have a substantial patch. And I now have a small patch in Tofino. You might have seen it on the garden tour? Here it is in it's Easter Sunday best with the canes tidied up and a new top dressing (thanks, Mom).
You do need something to support the plant(s) and this is a good method, with wire to loop the canes over as they grow.
Just leave a comment if you want to try this plant out. If I run out, I'll put you on a list for when I'm thinning the bed.
