Royal Sunset is an oldie but goodie for the desert Southwest. It has dark green, leathery, disease-resistant leaves, large flowers that can have great form (especially for a climber!), a nice scent, and color to knock your socks off. To top it all off, it has long, shapely buds.
It takes about three years for this climber to get fully established. It is well worth the wait. This is a great choice for the Desert Southwest if you are looking for a large-flowered climber.
