Thanks everyone for your kind comments.
This pepper is very hot...I tried small piece of it, it exploded with pain in my mouth.
I will overwinter this plant. This will be my first. I will cut it back and also, cut the roots, and put the plant in a smaller container. I read somewhere, that it is recommended to overwinter in a sand based potting mix, with very little nutrients. So plant stays dormant. Has anyone tried that?
