Sansevieria is a genus of about 70 species of flowering plants, native to Africa, Madagascar and southern Asia. Common names include mother-in-law’s tongue, devil’s tongue, jinn’s tongue, bow string hemp, snake plant and snake tongue. It is often included in the genus Dracaena; in the APG III classification system, both genera are placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also been placed in the former family Dracaenaceae.
They require bright filtered or indirect light. When growing outdoors, plant or position potted plants in areas of partial shade or full light but never in the direct light of the hot sun.
Sansevieria can tolerate a lack of watering but will fail quickly if over watered. Water plants moderately during the growing season and sparingly during winter. When growing outdoors, protect from over-abundant winter moisture such as heavy snow and cold rain.
For potted ones, grow in two parts soil-based potting mix and one part coarse grit. Sansevieria thrives in neutral to alkaline soil therefore apply a balanced fertilizer (20-20-20) at half strength once monthly.
