I bought two about 3 years ago - the Kamtchatica bore two berries the first year and they were quite sweet, but the Morena didn't have any at all, nor the following year - last year neither had any. This year, I moved them next to each other, though they were only a few pots away from each other, but nothing happened (I haven't even seen any flowers on them to pollinate them by hand myself! This year, I have bought a brand-new blackcurrant bush and put its pot in between them, but I'm not hopeful!
I live in Wales (Swansea) so it's possible our winters don't seem to suit them, though they both look very healthy!
