Rosa arkansana has compound odd-pinnate leaves with 5 to 11 leaflets, but typically has 7 or 9 leaflets. The lookalikes Rosa blanda (Smooth Wild Rose) has 5 or 7 sometimes 9 leaflets, Rosa acicularis (Prickly Wild Rose) has 5 or 7 leaflets, Rosa woodsii (Wood's Wild Rose, Western Rose) has 5 or 7 or sometimes 9 leaflets, and Rosa carolina (Carolina Rose, Pasture Rose) has 3 to 9 and typically 5 to 7 leaflets. Rosa blanda lacks prickles on the upper stems, but has prickles on the lower stems, and is typically 100 to 200 cm tall. Rosa woodsii can range from 20 to 200 cm or more in height, and has a very limited distribution range in Wisconsin with few reported observations, and is not listed as present in Wisconsin, Michigan, or Illinois by the FNA. Rosa arkansana can range from typically 60 to 150 cm tall, but the specimens in our local region are often around 45 cm or less in height. Rosa acicularis is typically 100 to 200 cm in height.
