Gardenia gjellerupii Thai Gardenia. Any info? Californiacentric?

I ran across this on a Philippines blog...Top says hardy to below freezing. I like the yellow flowers. I'm heavy in the reds and whites this would be a nice contrast. I think Top Tropicals is good with me borrowing their pic.

Can't help you Stan, but I wouldn't be surprised if this was one of those Gardenia flowers that started white and then turned this color.
