A friend sent me this plant image. It looks like a wild lily? I want to look really plant smart so hopefully someone comes up with an ID!
Looks like a Crinum.
I agree it's a crinum...maybe crinum macowanii, from South Africa. Its foliage grows pretty flat against the ground and it varies from white to white with more or fewer red stripes. A lot of the other crinums have more upright foliage. Bob
