Sansevieria are evergreen perennials that can grow anywhere from eight inches to 12 feet high. Their sword-like leaves are approximately two feet long. The foliage is stiff, broad, and upright, in a dark green color variegated with white and yellow striping. They are famous for their ability to survive in the most unsuitable growing conditions.
They are also renowned for their qualities that help purify the air we breathe. Since they produce oxygen mainly at night, snake plants make for a great bedroom companion.
