Just logged in today after a month of workmen here for house repairs, so I've been away from the forum. Yes, I start half my potatoes from seed each year, and half from tubers saved from them the previous season. The only difference being the tubers have some stored energy should there be a late freeze they can come back; the seedlings may freeze. This way I am assured of some kind of harvest.
This year we had 50.25 inches of rain, most of it falling in June and July, creating widespread flooding. Most of my larger potatoes rotted, but we were able to salvage about 50 thumb-sized spuds of every color from both the tubers and seed grown plants. None of mine made it to berry this year. I have them in a bowl dusted with lime and everyone thinks they look like Swedish wedding cookies.
If anyone has potato seeds/berries they don't want, I would be glad to add them to my mix. The main reason I grow from seed is that I want a diverse set of genetics in my plants. Gardening here is tough, and I need that diversity to develop vegetables that can withstand the extremes, so the more genetics the merrier.
