This sounds like Ismene x Festalis (Not Hymenocallis, although for some reason in the US in particular Ismene are called Hymenocallis all the time?).  Ismene and Hymenocallis are not the same thing despite this cross usage of the name.  My understanding is that the difference between Ismene and Hymenocallis is the fact that Ismene have the leaves bound together at the base by a sheath, whereas the Hymenocallis have their leaves free immediately they exit the ground.

I couldn't find an image of ismene on the wiki, so cannot comment. But the "Sheath" of the plant is definitely something one notices!
