Small, dark red chiles grow on this Mexican heirloom bush, and pack a wallop at 15,000 - 30,000 SHUs. Try Chile de Arbol pepper seeds in containers and move indoors into a greenhouse over winter, and it will come back as a perennial for several years. The thin-skinned fruits set generously on the plants, and are easy to dry. Once they are dry, they have a very long shelf life, and develop a very pleasant, hot, smoky, distinctive flavour. The chiles are borne on tall, upright plants (chile de arbol = "tree chile"), that will perform well in three to five gallon containers. Take homemade salsa to a whole new level with these wonderfully flavoured chile peppers.
