When this opens it will be a white lily-like flower. The plant was a large crawler- so I thought it was a vegetable. Haven't been able to find it through my research but I know someone out there will know!!
Added the white open flower to my Extra album.
Thanks to @julzmaioro for solving the mystery...this is a Moonflower! The only question I have is why it's planted outside a door to my Mom's retirement home when it causes delirium!!!
