Joyce Miller pointed out that Gloriosa tolerates moist conditions while dormant. More than that: it has been known to survive the winters here in the Washington, D.C. area. Winters here are dry when everything is frozen and wet when everything thaws. The plants which have survived the winter in my garden are in very protected sites, right against the house wall. I doubt that the soil freezes there, but it's cold and sometimes wet.
