My mom is wondering what this is. I think it at first popped up near her pond, she thought it was a weed but liked it becasue of the flowers. I do believe she moved it over to the area it is now, but I could be wrong. It has grown quickly in I think the two years she found it. I think it may be a DOGWOOD from the pictures that I have searched, but the petals of the flowers do not look the same. The flowers seem to cluster like that of a Rhododendron. It does have a slight fragrance from the flowers. What are your thoughts?
