Rosa arkansana (Prairie Rose or Wild Prairie Rose; syn. R. pratincola, R. suffulta, R. suffulta var. relicta) is a species of rose native to a large area of central North America, between the Appalachian and Rocky Mountains from Alberta, Manitoba, and Saskatchewan south to New Mexico, Texas and Indiana. There are two varieties:
- Rosa arkansana var. arkansana
- Rosa arkansana var. suffulta (Greene) Cockerell
The name Prairie Rose is also sometimes applied to Rosa blanda, also known as the Meadow Rose or Smooth Rose, which is also widely spread, but somewhat further to the north.
Wild Prairie Rose is the state flower of the U.S. states of Iowa and North Dakota. In Iowa, convention states the species is Rosa pratincola (currently treated as a synonym of Rosa arkansana). North Dakota, on the other hand, specifies either Rosa arkansana or Rosa blanda. Alberta's "wild rose" is Rosa acicularis.
