Discussion

Variety besseyi has been introduced west of its native range as an ornamental and fruit bearer for the home garden, where its adaptation to cold winters and hot, dry summers is a valuable asset. Cultivars were developed by breeders at the Morden Experimental Station in Manitoba and at the University of South Dakota.
