A common houseplant, the Sansevieria Hahnii is native to Asia and Africa. It can be recognized by its evergreen sword-shaped leaves that grow upright, and almost resemble artificial foliage. Snake plants are often used as home decor, as they’re pleasing to the eye, easy to care for, and require little water to survive. These plants are considered to be relatively safe, but they’re mildly toxic if consumed. Their leaves contain a poison that can cause swelling and numbness on the tongue if eaten in large doses. It’s wise to keep this plant away from children and animals. Snake plants help to filter indoor air.
