Sansevieria, also known as snake plant or mother-in-law's tongue, is a genus of about 70 species of flowering plants native to Africa and Madagascar. They are popular houseplants because of their ease of care and striking appearance.
Sansevieria plants have long, stiff, sword-shaped leaves that grow upright from a central rosette. The leaves are typically green with light green or yellow stripes, but some species have more elaborate patterns. The leaves can grow up to several feet tall, depending on the species. Sansevieria plants can also produce spikes of small, fragrant flowers in the summer, although this is less common when grown indoors.
Sansevieria plants are very easy to care for and can tolerate a wide range of conditions. They can grow in bright, indirect light as well as low light conditions, and prefer well-draining soil. They are drought-tolerant and should be watered only when the soil is completely dry to the touch. Overwatering can cause the roots to rot.
In addition to their ornamental value, Sansevieria plants have also been found to have air-purifying properties, removing toxins such as benzene, formaldehyde, and trichloroethylene from the air. This makes them a popular choice for improving indoor air quality.
