Phillip and Leslie - go for it!
I commit to making at least one white iris cross this coming season, if things are in bloom. (*Cough*, neglect, shade, *cough*.) And maybe a different cross, if the whites aren't in bloom.
(I really need to work on iris beds and iris planting this summer. But I hate the heat... and everything has to be protected from gophers... (* whine *))
