Sansevieria Trifasciata or snake plant or mother-in-law’s tongue is an evergreen perennial ornamental plant. The sword shaped leaves are colored light green with streaks of dark green all over the blade. On the margins of a leaf is a yellow vertical stripe, but there are varieties that don’t have such stripe. A leaf usually measures 28-35 inches long and 2-2.4 inches wide.
Listed by NASA as one of 12 house plants that can give better quality of air inside a house or a building, snake plant removes toxic gasses by passively absorbing toxins such as nitrogen oxides and formaldehyde. It is unlike most other plants that absorb carbon dioxide and release much oxygen during daytime. Snake plant takes away carbon dioxide and gives off oxygen in the evening. For this reason, it is an ideal ornamental plant inside the house or the bedroom to provide a slight boost of oxygen when one sleeps.
Snake plant can be propagated by cutting or dividing its rhizome. It is mostly planted on the ground or in pots with free draining soil. It can survive with less sunlight and water. Overwatering can cause the roots to decay which may kill the plant.
