Cascabella **

“A favorite for pickling, this pepper is generally used in its yellow stage, but it will turn red when left on the plant. Cone shaped, 1-1/4 inch long peppers range from 1,500 to 4,000 Scoville units. This variety is thick-fleshed and not to be confused with ‘Cascabel,’ a thin-skinned variety that is round and usually dried.”  Text from Tomato Growers Supply.
