*Size of pot - 17/20cm dia. *Air-Cleaning Properties The Sansevieria is an ideal plant for indoor spaces because it is a superb air purifier. Studies, including those performed by NASA, have consistently shown the plant to remove toxins such as formaldehyde, xylene, toluene, and nitrogen oxides—which means that industries and workspaces such as automotive plants and shops, aircraft plants, plywood, carpeting, paint makers and sellers, printing, and offices, where these chemicals abound in the products produced and used, would greatly benefit by keeping several Sansevieria around. The plant purifies air by absorbing toxins through the leaves and producing pure oxygen. In fact, the Sansevieria is an ideal bedroom plant. Whereas most other plants release carbon dioxide at night (in the absence of photosynthesis), the Sansevieria continues to produce oxygen. *Also known as Snake plant and Mother-In-Law's Tongue (Sansevieria trifasciata laurentii), Sansevieria require bright filtered or indirect light. When growing outdoors, plant or position potted plants in areas of partial shade or full light but never in the direct light of the hot sun.
