I've had Redneck Riviera for two years. This summer it rebloomed in zone 5a; it bloomed in early/mid July and then again in late August. It increased from 3 fans the first fall to 7 fans today. I have never been able to set a pod on it, but the pollen will occasionally work.
I really like the colors of the flower. My photo doesn't do the colors justice - they are much brighter in real life. I'd say twixanddud's photo is what mine looks like in real life.
