I could be wrong, but I thought I read somewhere that rocotos (C. pubescens) can tolerate a mild frost. The problem with rocotos is that they require a longer growing season that isn't available in many cooler climates. Generally, I would think that chiles that originated in the mountains would be better at cold tolerance. > I am writing an article on the the Best Cold tolerant Chillies for a > garden mag. > Serranos, manzanos, tepins head my list.
