Unexpected Rose

We had Rose bushes on either side of the walk one on the right (it bloomed a month ago) and one on the left. The one on the left died so I cleaned it out a couple of months ago and was going to plant another one. But when we got up this morning look what a surprise we had! Its just one tiny plant with a good sized Rose on it that looks to big for the plant to hold up.

Pretty ain't it! :)
