I've heard that chiles of different varieties can cross-pollinate, so a "mild" pepper crossed with a "hot" pepper could end up producing a cross that looks like a mild but has the heat of the hot pepper. My question is whether this will occur in the first generation of plants, or only in the seeds that those plants produce. If I'm not interested in saving seeds from my peppers for next year, do I have to worry about keeping hot & mild varieties separated? Thanks, Jeff Johnson
