I'm responding to my own query - the culprit that my mother loved so much was Loreley dated 1909, Mom's birth year, though I'm sure she never knew of the connection. Disciver it at Seneca Hills Perennials. Just goes to show that if you work at it, you probably can answer your own question.

Alan;
Check out Argyle Acres, they have alot of historic Iris. Loreley is a very common historic iris indeed! Several people have recently posted picture of LORELEY.
ROMEO is very pretty, also check out 'PEACOCKS EYE" as it may ring a bell as well!

Check out Superstition Gardens on Webshots for Rick Tasco grows both and helps out Historic Iris Preservation Society members. In fact the HIPS Sale is going on now until June 30th so you might want to look up the HIPS website. The members get first crack at the iris on sale but I do see both iris listed on the sales list. Worth asking about it on their site.

I bought Lorely in feb. from Iris City Gardens who also is closely associated with the HIPS. So is Argyle Acres. The addresses phone numbers and web links are listed on the HIPS site. On line ordering can be done with Argyle, Iris City not with Superstition.

Hope that helps on trying to locate these iris. Good luck.
