I hope to keep some for next year. I also bought some Colorado Rose, a red potato w/ white flesh, last spring. The eyes were barely visible on them and they never sprouted. Disappointing but I might buy some other variety next spring such as those yellow fingerlings. Space permitting. I could have planted four times as many PMs from the pound of seed potatoes they sent me.
Ronnigers, I know them well! Back in the early 90’s I used to order from them.
You might try some of the Alaskan taters. They have a short growing season up there, and might do well where you’re at.
I personally find potatoes to be one of the best growing crops. Onions too!
