At this point in their life, it is still hard to distinguish what kind of rose these babies are. If you are interested in trying to see what they are, I would leave them where they are this winter with some winter protection, and then next spring pot them up & hold them in a pot for a year or 2, evaluating them. DE is a "found rose" so there is no info as to its parents but it is classified in some sources as a Hyb. Musk so the babies may not resemble DE if they are the result of self-pollination & remember these babies may have had pollen carried in from another nearby rose so they may only be 1/2 DE.

We used to sell DE open pollenated seedlings as a fund raiser at our local rose club. They were all different but similar. Everyone seemed to love the one that they purchased.

My open pollinated seedlings are in general as good or better than the original. I donated many small D.E. seedlings to our local rose society for their annual spring plant sale; and they were a very popular item with lots of positive feedback."

Good luck to you. Probably not DE but maybe close enough to make you happy.
