I've got a sweet variegated iris with a white flower called 'Striped Britches'. I'm just over the hill from you in Soquel. Be happy to share with you next year. It's about the same ht. as the pallidas with a nice clean white variegation that doesn't show in this picture.
I have a higher mortality rate w/ Blue J iris than those from other growers... Maybe they just don't like California...
I too am variegated obsessed.. I'll bet you probably have the variegated daylily that Monrovia was growing too (forget the name).
