Snake plants (Sansevieria spp.) are notable for their extreme hardiness. Also called mother-in-law's tongue, these plants are easy to grow, according to Colorado State University Extension's website, and rarely suffer from insect pests or diseases. The vertical, twisting leaves can be variegated or striped, depending on the cultivar and thrive in containers. For these reasons, they are often grown as houseplants. Although hardy, snake plants can suffer from conditions that yellow and curl the leaves.
