Ok guy's here's one I found on another web.. ~~~~~~~~~~~~~~~~~~~~ Between me and my husband, we've grown a LOT of different types of peppers and the only ones I know of that are cold hardy at all are chili petins (pronounced "peteens"). My mom-in-law has a 30-year old plant that's in the ground outside her house in Bertram, Texas. It doesn't get much lower than 20 very often, ~~~~~~~~~~~~~~~~~~~~~~~~~~ L.B.
