Anyone who does gardening at home also knows that given weather considerations and cross-pollinating (for some reason peppers cross pollinate very easily) one pepper from the same plant will have a completely different heat level than another one from the same plant. I have taken to growing "super cayenne" rather than jalapeno. They seem to be more consistent. But i used to have a balcony garden, many moons ago. A friend had given us what we called "papal peppers" because he took them from a bush in Vatican City. They were upright and yellow. I used the seeds from them the first year, got upright, and to us medium heat (heat is definitely subjective). Took those seeds the third year and got orange, down pointing peppers (a neighbor was growing cayennes and we had pepper sex going on!)
