Have you heard of the ‘Thai Dragon’ pepper? How does it rate on your heat scale? I am very familiar with the chiltepin and am wondering how the Thai Dragon rates against it.
Here’s what http://www.chileplants.com/ says about Thai Dragon: "THAI HOT DRAGON HYBRID-very hot; 3-4" by 1/2" wide; thin-skinned fruits; eight times hotter than jalapeno; each plant can produce 150-200 pods; good for drying." I would say that it’s not as hot as the chiltepin.
