Thanks for that, Brandon - I don't know if I've ever seen the original species rose before, in situ, since I'm not from the US and it isn't a weed problem here or in the UK, AFAIK. Those fringed stipules are often helpful when narrowing down an unknown/ NOID rose to somewhere in the multiflora family (or not). Not that I'm any kind of expert! <3

Nice educational piece, Brandon. Much appreciated.

R. multiflora is everywhere here in PA. Some wild strains actually have huge clusters of blooms. Almost everywhere along country roads, R. multiflora is seen about now, blooming. Right along the growth in undisturbed sections of road, just inside of the road's berm, there you see R. multiflora blooming away. Sun or shade, it's all the same, R. multiflora is everywhere.
