Here is a link that might be useful: Plantlilies

Thanks,apparently mysavanna has gone out of business, their phone is disconnected. And Plantlilies does not mention rhodos - if you have any other ideas please share them.

Gail, you could try calling Plantlilies. They do not have rhodos in their current catalog, but they list it as a lily they have grown in the past, and they note that they grow others as well. Maybe they would cut some loose for you.
