Hi Michael, I probably get less frost than you living a bare 5-6 hundred meters from the beach and 500 kilometers north of you, but those small upright chiles of mine that you thought may have been a asian hybrid bred for ease of harvesting have survived several frosts 4-5 years ago including one day when we had a temperature of -3 degrees centigrade at 5 am here. Luke in Oz p.s. Manzano repotted in larger pot, will go into garden about mid August. Poblano has 5 flowers on it, erected that shade house beside the western wall and putting my Chiles to rest for the winter.
