I thought Snowbank was the only patented Brug at least it is the only one that carries the "PPAF" (Plant Patent Applied For) designation after the cultivar name. Kyle Courtney is Inca Sun's hybridizer and I presume the person who registered it. I remember that he posted photos of it in Dave's Garden ages ago. Only later did I see it for sale through Logee's. If Logee's changed the name of its Inca Sun, it would probably be in even more trouble for hijacking the plant.
Sandi, did you ever see it for sale by Logee's or did you get the Inca Gold cuttings from some one else? I have not been able to find much about it. I have a feeling that some one mislabeled it.
