Hi, I was reading information recently about the Mexican species of Hymenocallis--they are a mixed bag. It is hard to find good information about some of them other than that some grow along rivers and streams and others come from more xeric conditions. I suppose those from riverine areas might do well with big pots (10-gallon or more) and sandy loam, watered well from late winter till at least midsummer. But, I'm not really sure about that, and I suspect that they might be OK here outside year round in big pots as long as they have fast-draining soil. But, I'm just guessing. As for the xeric types, I think they might like similar soil but would enjoy rain protection part of the year. If anyone has any other information I'd enjoy hearing about these plants. I've got a few seeds of different types coming along and am trying to decide what to do for them. Cordially, Joe, still warm and humid, no rain for 2 weeks
