Prairie rose was used for a variety of ailments by Indians. The petals were used for perfume. The hips (isn't that a strange name for a nuticious and fat free fruit) were eaten, and among those used for pemmican. Eating rose hips, with their thin flesh and fuzzy seeds, is not very pleasant, but if you're hungry . . .
Canada has had a program to breed more winter hardy roses. Cultivated varieties such as "Prairie Joy" and "Winnepeg Parks" include Rosa arkansana.
