I have 2 other photos but could not upload them. This tree just appeared in my yard, has grown very fast and is 8 feet tall now. It is near the water line in my yard. Is this a problem? I have nearly all native plants in my yard and would love to keep it if it's native. People have told me it will damage the water line in its search for water. Is there an email address I can send the other photos to? They are closeups of the leaves and the branch.
