Hi Peter! Actually, I do have some of the other species of peppers. The problem is that the C Annuums are the only ones that bear fruit quick enough - last year half the Baccatums (sp?) didn't even get fruit on them before the frosts hit. I do get some of the other species of peppers, later in the season, but not that many. Here in PA the growing season is over by October, even using plastic sheeting to cover the peppers at night- it's just too cold and dismal to go much later. And the plants don't go in the ground before May. The earlier C Annuums are pretty much done before fall begins. Our winters here are typically in the range of 10 to 40 F (-12 to 5 C). I don't even get any "volunteers" from seeds left from the previous year, I guess due to the cold. So I suppose that here it isn't really which peppers can withstand light frosts, as the other species might be able to, but rather, which species will produce fruit before the hard freezes come. On the bright side, THIS YEAR I got earlier C Baccatums which are already getting flowers on them. YAHOOOOOOO!!!!!!!!!!!!!!!!! AIN'T SUMMER GRAND???? Brad
