THUNBERGIA - BLACK EYED SUSAN VINE - Pinetree Garden Seeds - Flowers - Annual in Zone but will still grow feet, rambling over itself if it is not trellised. Can be a ground cover if you let the vines trail.
Hide the downspout with a trellis. Hide your rain spout by transforming into a decorative climbing support for your favorite flowering climbing vine. I really like this idea and it looks great too. - Gardening For Life
