Probably multiflora rose, highly invasive and a huge problem in many parts of the country. I think I see fringed stipules at the base of the leaf and that is one characteristic of multiflora rose. Native roses have smooth stipules. Flowers on multiflora rose can be white or pink.

Wow that's not good. I was surprised to see a rose flowering in the shade. There were many plants so the invasive-ness is believable.

is this the stipule?

Yes that is a fringed stipule.

this rose.. blooms once per year ... and a rose grower would say.. with carpy little flowers.. and you will note.. very early in spring ...

otherwise its a highly aggressive green bush the rest of the year ... imo.. of no use in the usual garden ...

so it gets the energy it needs to flower.. not only when the trees are less leaved.. but can store a lot during the season with its 50 billion green leaves.. shade or not ...

if you planted a foo foo hybrid T rose in there.. it most likely.. just couldnt get its act together ... to flower ...
