Pasture Rose (Rosa carolina)

http://en.wikipedia.org/wiki/Rosa_carolina

 

Pasture Rose is perennial woody plant native to eastern North America. It is found in prairies, openings in woodlands, oak savannas, limestone glades, and sand dunes near bodies of water. Pasture Rose can be locally common especially in abandoned fields, along railroads, fence rows, and other waste areas. It like mesic conditions, but can tolerate some moisture. The flowers look like Swamp Rose, but it lacks red styles in the center of the flower. Also, pasture rose would not be found in wetlands, the thorns are not curved, and is not even close as tall as how Swamp Rose can get. Pasture Rose can often times be seen sprawling on the ground as that is how I have only seen it in my experience.
