Just saw this listed at Rogue Valley Roses, although it's out of stock now. I've been looking for it, so I don't think it was there before.

Very clean foliage -- it seems impervious to disease -- of a nice dark green color and medium gloss. The flowers are a nice yellow, with good form and last well on the bush and drop cleanly. Unfortunately, the plant has been very stingy with the blooms so far. It has been in the ground for two years in my mother's garden in zone 9a, Northern California, and hasn't flowered much. Perhaps in its third year, it will take off and perform up to expectation. I'm keeping my fingers crossed!
