Sansevieria trifasciata ‘Laurentii’ is a slow-growing succulent that forms a tight clump of many erect, strap-shaped, sharply-pointed, dark green leaves with gray-green zig-zag horizontal bands and broad yellow margins. It spreads by creeping rhizomes that are sometimes above ground, sometimes underground. Leaves grow from a basal rosette. They are up to 1.2 m, usually about 60 cm tall, and 6 cm wide.
The fragrant flowers are tubular, greenish-white, and appear in erect racemes within the foliage in spring. They rarely appear on indoor plants.
USDA hardiness zones 10a to 11b: from -1.1 °C to +10 °C.
How to Grow and Care
Place Sansevierias in moderately bright or filtered light. Good locations include a spot in front of a north-facing window or front of a bright, sunny window covered by a sheer curtain. Although the plant tolerates low light, bright light brings out the colors in the leaves. However, intense light may cause the edges of the leaves to turn yellow.
Allow the soil to dry completely before watering, and water deeply until water drips through the drainage hole. Allow the pot to drain, and discard the water in the saucer. Never allow the soil to become soggy; never let the pot stand in water. Water sparingly throughout the winter. Like most succulent plants that store water in their leaves, Sansevieria rots quickly in excessively wet soil.
Place Sansevieria at average room temperature. Protect the plant from drafts and cold temperatures as it is damaged below 10 °C.
Feed the plant once every three weeks throughout the summer. Use a general-purpose fertilizer for houseplants diluted to one-half the strength suggested on the container. Sansevieria is a light feeder, and too much fertilizer makes the leaves fall over.
