A Sansevieria plant, also called a Snake plant, Mother in Law’s Tongue, Bowstring Hemp, and Devil’s Tongue, was originally found growing in Africa and southern Asia. This is a hardy, almost impossible to kill houseplant that thrives on neglect. Sansevieria plants can grow in bright light or shade, are not harmed by low humidity or cold drafts, rarely need to be repotted, and are drought resistant. The only way to kill a sansevieria is by over watering or keeping it in temperatures 40°F ( 4.4°C) or less for aa extended period of time
Description of a Sansevieria Plant
A Sansevieria plant can be used as a table plant when small, or a stately floor plant as it mature. The leaves are arranged and grow in a rosette pattern. Sansevieria plants developed hard, leathery leaves to adapt to the dry, arid regions where they were originally found growing. The thick, succulent leaves store water and the thick leaf cuticles help to reduce the loss of moisture. The flowers of a sansevieria are usually greenish-white and grow atop a long, leafless stem. Flowering usually occurs during the summer or fall.
Popular Sansevieria Varieties
1. S. Trifasciata is the most popular variety sold. It has long, sword-like, succulent leaves that grow about 2-3ft tall. The many trifasciata types include the S. Futuro Robusta” that has grayish green muted patterns on the leaves; and the S. laurentii with variegated leaves that have bright golden edges;
2. S. Zelanica is a bit shorter than the trifasciata and has dark green leaves with creamy white horizontal pattern.
3. S. Hahnii varieties have thick, compact, very short (4”) rosettes of fleshy leaves. The Golden Hahnii and the Silver Hahnii are two popular varieties.
4. S. Cylindrica is a stemless plant with stiff, tall, narrow, grey-green leaves that have horizontal, dark green stripes.
5. S. Braided Cylindrica is created by gently braiding the tall, narrow stems of S. Cylindrica and then gathering the tops of the stems together with a decorative tie.

Sansevieria plant diseases: Red leaf spot disease causes red spots on the plant leaves. Remove any diseased leaves and spray the plant with a fungicide. Keep the leaves dry and provide good air circulation to prevent red leaf spot disease from reinfecting the plant. Over- watering a sansevieria results in bacterial root rot. Replace the wet soil with dry Sansevieria plant diseases: Red leaf spot disease causes reddish brown spots on the leaves. Remove the diseased leaves, spray the plant with a fungicide, provide good air circulation, and keep the leaves dry. Root rot due to over watering is the main reason a sansevieria plant dies.
