From the Christopher Phillips Rare Seed Collection R5--Release #5 on December 9, 2014. These thin walled 3/4 inch peppers are said to originate from Vietnam. It is a Capsicum frutescens and the pods ripen from green to red. When ripe, the pods slip right off the calyx. They have a nice heat level and the burn is slightly delayed so wait for a little while before eating them too fast!
