Ask the Expert: I found this and was wondering what it was

Spider Lily

I found this flower on the side of the road and have never seen one like it. Can you tell me what type of flower it is?
Thank you. Suzanne

The lovely white flower is commonly called Spider Lily.  It is a Hymenocallis. I'm not sure which Hymenocallis it is.  It could be one of the following: Hymenocallis lirisome, Hymenocallis littoralis or Hymenocallis occidentalis.  They usually bloom summer through autumn.
