These chiles are so good it is a shame that more people do not know about them in North America. I grew them in a container in Northern Arizona and they went through winter outside with regular freezes. Once spring came around and the weather warmed up guess what came back up from the roots? Yes these will regenerate themselves from their roots after going through a whole winter. I neglected them also and didn't water that pot because I was sure they would die just like any other Chile/pepper plant after a freeze. I am definitely growing these out again in 2020. Their flavor and spiciness profile contains things lost in domestication. They may be medicinal.
