Holy cow! I'd never heard of Yvonne or her awesome Salvias until you mentioned her. I Googled "Salvia Yvonne" and found this exchange post here at GW. If there are no seeds left, maybe someone knows where you can get them.

Good luck in your quest!

Go over to the seed exchange and ask there. A lot of people have them. I have a few but didn't get them planted yet - those and a few others that I meant to do this weekend and never got around to.
