What is this?
Cleaning up junk. found large rose bush, rather rose patch. Dozens (likely over 100) of stems in area about 4 foot in diameter. Bush is about 5 foot high, 8 foot in diameter. Area was mowed several years ago and to my knowledge has never had roses planted in it. The stems all appear to come from a common underground root system. I had roses many years ago in another area and could have thrown a dead bush here. There was trash here a while ago. Picture collage attached. Can anyone id type of plant or variety? Also would like to know if this could be separated and transplanted? it appears to survive our winters. Any guesses appreciated
