About
Opuntia fragilis, known by the common names brittle pricklypear and little prickly pear, is a prickly pear cactus native to much of western North America.
Where it grows
It is native to every US state west of North Dakota and Texas as well as some midwestern states such as Minnesota, Illinois, Iowa, Wisconsin, and Michigan. However, it is often only present in one area of a state, for example only in Siskiyou County, California at the northern edge of the state. It also occurs in every Canadian province from Ontario to the Pacific Coast. It is known to grow farther north than any other cactus, occurring at as far north as the watershed of the Peace River, ~56°N latitude in British Columbia. There is an isolated and possibly genetically unique population in Eastern Ontario known as the "Kaladar population".
