height 2–6ft
width 1–3ft
tolerates Drought, Heat, Pots, Neglect
When soil is completely dry.
Sanevieria are some of the toughest plants out there, as long as you let them go dry between waterings. Generally indoors this will mean watering every three to five weeks. We know a grower who swears by watering their Sansevieria whenever the rent is due. If however you grow this plant in some direct sun it will want water when it approaches dryness or right when it is completely dry. If allowed to go too dry this plant developed crips brown tips.

Indoor Exposure Guide


Direct Sun
Beams of light hitting the plant near a window four or more hours a day. The most intense light. If you're in a direct sun spot, you can feel the warmth of the sun on your skin.

Partial Direct
Occurs when you have a plant that is in less intense direct sunlight. This happens when a plant is in a few hours of direct morning sun, or an hour or less of direct afternoon sun. It also happens when a plant is in direct sun, but more than six feet from a window, where the light is diffused.

Bright Indirect
This is just beyond the direct beam of light (or through cracked blinds or a sheer curtain filtering direct sun). Bright indirect areas are characterized by a place where you can sit and read a novel comfortably without artificial light.

Moderate Indirect
Beyond the bright indirect light. In these areas you wouldn't turn on a light walking through the room, but if you were hanging out there you would probably have the lights on, even during the day.

Low Light
Dim spots, usually the backs of rooms or hallways where you would always turn lights on, even if just walking in to grab something.


Growing Notes

Good drainage is critical to Sansevieria care.
The leaves of this plant last years, even decades. They will over time get dull looking and show physical damage; when they do you can thin them out at or just below the soil surface.
Most sansevieria, including this one, are stoloniferous, meaning that they spread by thick underground (or sometimes above ground) shoots called stolons. It is very easy to propagate your sansevieria by finding a growth point and following the fleshy stolon back to the previous growth point. Cut it there and replant the stolon, with roots and all. Those with above ground stolons can be removed and planted once you see roots forming along the stolons.
This plant isn’t the best choice for low light indoors, where it will last a long time, but become floppy and collapse under its large leaves. Direct diffuse to bright indirect is best.

Special Interest

You’ll see this plant sold as Sansevieria ‘Shark Fin’ or Sansevieria ‘Whale Fin’. These are just plants that have been cut and rooted midway up the leaf to give the appearance of a lower fatter leaf. Unfortunately any new leaves that come up will revert to the original form, with a thin base and elongated almond shape.
