One of our favorite plants for the Indoor Air Plan is the snake plant (sansevieria). They are resilient to drought and lack of natural light, while looking lush and filtering toxins like formaldehyde and benzene out of the air. Their leaves are rigid and vertical, but mottled with different shades of green for a wonderful level of dimension. The sharp looking leaves have even given rise to a second name for the plant: Mother-In-Law’s Tongue.
