Pretty in pink

This beautiful lily pops up just next to one of my cottages every year in Nov or December.  For the rest of the year it looks like two or three shriveled leaves.  It’s commonly known as a veld lily or river lily and is one of the Crinum lilies.  I am still arguing with all my sources as to which one it is.  Depending on the book or source, my crinum changes names.

I think it may be a crinum stuhlmannii but one of my books disagrees.

Anyone have an opinion?
