I'll post this also on the Lilly forum just in case. An older neighbor (since moved) gave me this a few years ago saying he dug it up from 150 yr old farmhouse. He called it a Crinium. This is 3rd year in my yard, was honestly thinking of taking it out because it hadn't done anything. Apart from growing huge thick leaves. When finally "Voila" this year it blooms! Slight sweet smell. Can any one tell me the name and what does one do with the huge leaves once blooms are done?
Thanks for advice
