this time of year its perfect weather for them and theyl put on a bumper of hot and bells.
yep frost will kill them and make the peppers wilt. i wish i had a warm place to pot and save my big bell plants and transplant them in spring.3 years ago i left mine till the day before it was supposed to frost..we canned bunch and i hung the rest in the barn to dry out and ground themin the blender later,,I still have 6 quarts canned and 3 pints of ground ,,
if they are longer than 2" probably cayenne, probably dragon. those are the ones i usually grow. about 50k scoville, not too bad. cayenne and jalepeno probably the two most flavorable.i picked up 2 pepper plants somewhere (home depot/walmarts/local nursery) just to "fill out the end of a row" . These pepper plants make tons of long, skinny, green peppers that turn red. And they are so HOT , even my son can't eat one, and he'll eat anything hot. Best I can guess, is they are Tai Chillies .
My bananna peppers did extremely well this year too, and had an unusually sweet taste this year.
They look like Thai Chilli, but I guess they could be cayenne. They look similar to my cowhorn peppers, but skinnierif they are longer than 2" probably cayenne, probably dragon. those are the ones i usually grow. about 50k scoville, not too bad. cayenne and jalepeno probably the two most flavorable.
