I received a flyer from Redwood City seed Co. They are selling a variety of Oaxaca pepper seeds (Chihuacle Amarillo, Chilhuacle Negro, Chilhuacle Rojo, Chiltepec, Costeno Amarillo, Costeno Rojo, and De Agua). I was just curious is anyone knows anything about these peppers. Most of what I've found says they ONLY grow in Oaxaca (apparently not), also Craig at Redwood states on the flyer, they are only available every 10 yrs. Why is that? I was considering buying the collection, but I wanted to find out some info on them first. So, does anyone have any knowledge or experience with these peppers? Any info would be greatly appreciated.
