Here's the thing: the maris peer, and the desiree which I grew from supermarket spuds are fine, but they've not been great crops. That's half a sack of desiree from 2 rows, about 16 seed potatoes. The other ones in the photo are from an odds and sods kind of row, I think there were 5 maris piper, and can't remember what else. Anyway, the maris piper were a wee kind of novelty birthday present, but proper seed potatoes, but they've cropped better than anything.
So, next year I'm going to get good seed potatoes, and I'm going to get varieties that I can't buy in the supermarket, something a bit different.
