Muddymitts - thank you too for the photos of red irises ! I'm taking notes!
...and getting back to my original question about the i.d. of my two-tone iris.
One reason I think that it's name is Gladys Austin, and not Megabucks, is because
I got the iris in the mid-'80's, and Megabucks, if I recall correctly, was introduced in 1990.
I'll have lots of Gladys to give away.
