These were given to me a couple fo years ago and are doing well in my yard. The lady that gave them to me said her great-grandmother had brought them with her to Tennessee from South Carolina about 100 years ago. Other than being some kind of lily I have no idea what they are. They do look somewhat like images I've found of hippeastrum breviflorum but what I've read tells me that they are generally found in South America. Anyone have any ideas?
