Here is an attractive way to get super heat.  The pods turn green to pale yellow to almost florescent white when fully ripe.  Our plant loaded up with an abundance of pods.  Like all super hot peppers it is slow to ripen and needs as much heat as you can provide.  We grew ours in large pots and kept them in a greenhouse.  With temperature’s dropping into the 20’s, I have moved it into the barn to see if I can keep it alive until spring.  Extreme heat!  Use with caution!
