Atamasco Lily source
Just a heads up to anyone interested. I do not work for this guy. I have, however, ordered from him in the past. He has Atamasco lilies for sale on Ebay. Look for the seller "bulbsnmore". I think his prices are reasonable and I have been happy with my purchases from him.
I love my Atamascos and if you live in Zone 7 or higher, I'm betting you will too. They are hard to find.
