Because it has thorns, and it looks maybe something like another rose bush we have on the other side of the house.


It's under a lilac tree.
We moved here in the winter 2011 / 2012, so this is our 2nd spring here.
I can't imagine how it could be there when I cleared out under this lilac tree last year tons.
Could it grow that big (it's about 1ft tall) from nothing just this spring?
And if so where did it come from? The only other rose bush we have is on the other side of the house.
I'd put off weeding under this lilac tree because there was a robin nesting with eggs in the lilac tree.
But apparently she died - nest was abandoned - her mate is still in our front yard.\I found this yesterday after clearing out almost 2 weeks of creeping charlie...
And I mean MONDO creeping charlie, piled up so that just the top of this bush was peeking out, and my husband pointed it out and said "hey don't pull that it's a rose".
So is it a rose?
If a close-up of the leaves is needed, let me know & I'll get a macro shot.
