I have tried cabbage for the whites too, but only get the little cabbage loopers, which are cute, but not as exiting as the whites. I also have tried hollyhock for painted ladies (or American - can't remember which) and snapdragons for buckeyes, but have not gotten any. I like all of these flowers anyway so if it takes a few years for the butterflies to find them, then I can wait. I didn't know they might come along after a few years, Mona.
Passionvine works great for gulf frittilaries in this area. I want to get some of the yellow candlestick plant, Senna, I think, for Sulphurs but haven't found it reasonably priced.
