Marjorie Hausermann is one of the old standard Hausermann stock whites that they grew for corsages for years. I have found it in one of their old catalogs, but that would not be of any help. It was bred into a lot of the modern white. In my opinion, this is one of the Golden Oldies. It and Bob Betts 'White Lightening' are some of the best whites ever - when Bob Betts hit the market in 1945 (little before my time) it took about every award offered. It is the idea 1940's corsage orchid!
You know - I just looked online and Hausemann's is offering Marjorie Hausermann 'York' at this time in a 6' pot for $32.95?
I will be ordering one myself.
