Uncontrolled hybrid - just for fun
I have a pepper patch with only Bhut Jolokia, Anaheim and Chilpetine plants. The Chilpetines readily re-seed so there are many new volunteer plants every year.
One of them has long peppers, thin wall with a bumpy texture on the walls. The peppers readily release from plant when ripe (like wild peppers & Chilpetine do)
I figure it is either a cross of Chilpetine and Bhut or Chilpetine and Anaheim.
Just for fun.
