Is this a rose bush (very thorny)
I have another post here about a mystery rose bush at my mom's rental home, owned by a friend that inherited it. The garden is in pretty bad shape. Anyway, I took a picture of this a month or so ago as I wasn't sure if it were a rose plant or not. It is FULL of tiny thorns. The leaves resemble rose leaves. But I am wondering if it is a rose or a scary weed.
