I think I got a Sansevieria parva today which is supposed to flower in summer and smell like hyacinths (the common name is Kenya Hyacinth). Of course there was no tag on the plant and the workers didn't know the name either (besides sansevieria). It fits the bill of having 9"-16" long leaves that are around an inch across. The plant itself is huge! About 31" across and 22" tall. It's in a hanging basket and has underground runners.
I suppose I'll have to wait until summer and see if it blooms and has fragrant flowers?
I'm a fragrance nut so I'm pretty stoked if it is S. parva. :)
