Description
Sansevieria trifasciata ‘Hahnii’ is a lovely succulent that forms a compact cluster of elegant funnel-shaped rosettes of 2 to 6 leaves. It grows up to 20 cm tall. Leaves are whitish-green, somewhat banded, and irregularly mottled with a darker shade. They are usually about 15 cm tall and 7 cm wide.
The sweetly scented flowers are greenish-white and appear in clusters on erect up to 40 cm tall stalks. Sansevieria trifasciata can bloom in summer or fall, but this cultivar rarely seems to do so.
Hardiness
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 then discard the water that remains 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 of the strength suggested on the container. Sansevieria is a light feeder, and too much fertilizer makes the leaves fall over.
