We love this plant! Sansevieria masoniana 'whale fin' is an absolute treat. Though sansevieria are often touted as low-light plants, you'll find vigorous, active growth comes easy with high & even direct light. Allow to dry completely & water thoroughly. This particular species grows leaves as wide as 1 foot & heights up to 4 feet.
*DNA testing has determined that the genus formerly classified as sansevieria are actually dracaena, but old habits die hard, & for now we'll continue using "sansevieria." ;P
