Well since it's not my plant I don't know a lot about it's growth. He said it stays short (I assumed about 6 inches), The larger leaf in the photo is about 5 inches. His description... it grows wider rather than taller - just green pointed leaves. I'd assume they point upward.
I think it probably is a sansevieria. Not sure it's the dwarf one in the photo... I wasn't thinking it grew in rosettes like that. I'll have to get some more information from him. Thanks for all the help u-2.
