After wanting one for years (and finding it for a decent price), I finally own a Whale Fin Snake Plant. I know Snake plants are now part of the dracaena family but I still consider them sansevieria; just like Pluto will ALWAYS be a planet to me.
Whale Fin (Dracaena Masoniana or Sansevieria Masoniana)
Light: Low to Bright Indirect
Water : When soil is dry
