Is this from the original breeding? I wasn't interested in the cross initially and did not get any seedlings. only to regret after seeing some of the amazing flowers out of this cross.
Fred made sib cross and I got one (Richard Brandon x Richard Brandon) last year. It bloomed last fall and again in bloom this fall.
Mine look very similar to yours, yellow with strong brown hue. Buttercrotch, should I call it?

I like how white the staminode shield is on yours. Mine is spotted brownish.
The fragrance is amazing!!
