I'm having a hard time believing that it is not Hymenocallis x festalis. It's a dead ringer for Hymenocallis x festalis as I grow it. The 125cm height is however a puzzle. It's maybe 90 cm here. Was Carol's plant grown under glass? Jim McKenney email@example.com Montgomery County, Maryland, USA, USDA zone 7, where the Hymenocallis of the Ismene group are highly appreciated.
