Sansevieria trifasciata is commonly called the snake plant, because of the shape of its leaves, or mother-in-law's tongue because of their sharpness. Snake plant will survive in a wide range of conditions. They tolerate the low light conditions and are very drought tolerant. As many indoor plants, snake plant is a very efficient air filter/purifier.
Dracaena require less water than most indoor plants. Keep them hydrated by misting the leaves with water and keeping the soil lightly misted (never soggy) as well with good drainage. Always allow the top soil to dry out before watering. Do not overwater, as it may cause root rot.
