Definitely looks like Mr. Lees/Cactus Pete derived this beauty from Knebel's "Heureka" (AKA Mussolini). You can see the legacy of this bloom in the Evelyn Shiraki hybrids, they have that same lovely form and shimmer to them.
Like a dummy, I was trying to reposition this plant for a photo. Holding the tip with the three blooms, the plant fell backwards. The part with the blooms broke right off in my hands. The rest of the plant, non the worse for the wear. Need to plant this one up in a hanging basket anyway, it LOVES to grow and bloom, apparently.
Garden Gnome Thunder looks on in disbelief.......
Into the indoor studio for a couple nice photos before the inevitable premature fade :(
