Joseph I'm intrigued by the cold tolerant tomato plants. I'm curios if you've worked with pepper plants the same? I have some small sweets one plant that survived the first two hits of frost(with damage) and I didn't consciously mark thesave seeds from that plant. I did notice though that the seeds from that line sprouted within days this spring. Long before most tomatoes planted the same time in the unheated greenhouse. I will have to pay closer attention in the fall and may you some trials next year...
