ASPARAGACEAE

 Unfortunately, there's not much to say about this Albuca yet, as I haven't seen it in bloom to make a correct identification. It might be an undescribed species that's been around in cultivation for a while. It's very likely a species from South Africa that's quite large.

 Full sun and most likely a winter grower (leave dry in summer). Water from September to May/June, but be careful not to let them sit too wet for too long during the cold winter months to prevent rot.
