After all kinds of web surfing trying to figure out which white fragrant lilies I could add to my garden to have bloom right now, I still don't have any in bloom at the moment. I am trying again and placed an order with B&D Lilies for Siberia (Oriental), Gizmo (Oriental / Easter Lily) and Zambesi (Orienpet). It is really hard to find pure white hybrids, but those are pretty close.
Siberia should be a late bloomer according to the info I found, but they have it listed as blooming mid to late July while they have Casablanca blooming in August, so I am hoping it will bloom earlier here too.
(My Asiatic hybrids just finished up and I am waiting for Orientals to start which is usually the first week of August, so it is just this week that I have nothing!)
