'Twilight' - Jackson & Perkins

I stumbled upon the HMF listing for ‘Twilight’ (Boerner, 1955) and I was wondering if anyone knows of a source for this rose?

No, it’s one I have had on my radar for a very long time. Evidently it was so weak and unhealthy, it didn’t hang around. You can still find Brownie and Tantarra was a Balinese seedling, and Twilight may exist somewhere in Japan as they seem to be able to pull such rarities out of thin air, but there is no documentation of it, and many other weird ones growing anywhere or being offered for sale commercially. Believe me, I have looked and watched for them. If you have Lavender Pinocchio, I can send you Grey Pearl pollen to put on it to see if you can raise similar results. I’m putting Californica and Secret Garden on Lilac Charm and don’t want the LC pollen if you’d like it to play with.
