That one caught my eye, too, Lorn. And along with many others:
The red one on the bottom left:
Almost as good as 'Awesome':
Not even very lily-like:
And I especially like this, Anthony.
Very glad you took this pic, Della. Anthony's photo didn't show the glory at all.
It deserves a much better image.
Anthony, If I understanding you right, this is
(White Henryi x Madame Butterfly) x (White Henryi x Madame Butterfly)
If that is correct, then technically it is not a backcross, it a F2 generation seedling.
A backcross would be your F1 generation seedling (White Henryi x Madame Butterfly) crossed with one of its parents White Henryi
or Madame Butterfly).
I never crossed White Henryi x Madame Butterfly, but I did Madame Butterfly x White Henryi. Still have three or four of the best clones.
