Hi Jim and all, We grow lots of Hymenocallis here, almost all in pots. Most are carried over in winter in a heated storage building at ca. 45-55°F, bone-dry, and in the dark. These are mainly the Mexican species that go quite dormant in winter. For the evergreen sorts, we store the pots under the benches in a cool greenhouse (always above freezing) and water on rare occasions during winter. 'Tropical Giant' is one that is more or less evergreen. In most winters, in the short, dark days and the cool greenhouse, even the evergreen varieties go dormant for a while. Good luck!
