One of the hardiest of all indoor plants is Sansevieria. Erect, dark green, lance shaped leaves emerge from a central rosette.
Golden yellow stripes along the margins and horizontal bands of grayish green create a striking pattern similar to the coloring of an exotic snake S. Trifasciata “Hahnii” and S. trifasciata “Golden Hahnii’. A relative, S.cylindrica, has round leaves with pointed tips. Mature plants produce fragrant, pink or white blooms in spring.
Given proper care, sansevieria makes a showy accent for any indoor decor. Place it in a brightly lit, warm location, and water it regularly, as soon as the soil becomes dry. Overwatering will cause root rot. Fertilize every 2 or 3 month.
Light: Place in a bright, indirectly lit south, east or west window.
Water: Water thoroughly when the soil ½ inch below the surface is dry. Discar drainage.
Humidity: Dry air generally does no harm.
Temperatures: 50° F to 55° F at night, 65° F to 70° F during the day.
Fertilization: Fertilize lightly with a low-nitrogen fertilizer in spring and summer. Continue fertilizing, though even more lightly, through fall and winter for succulents that grow actively the year around.
Propagation: Stem cuttings and offsets root easily. Dry the offset or cutting for a few days until a callus forms, then plant in a well-drained potting mix and keep barely moist. Many succulents can also be reproduced from leaf cuttings.
Grooming: Cut off flower stalks as the blooms age.
Repotting: Repot only every 3 or 4 years, when essential. Use a shallow pot and a very porous soil.
Problems: Root rot can result from soggy soil caused by poor drainage or excessive watering. Stem and leaf rot may be caused by cool, damp air. Leaves wilt and discolor from too much water, especially in winter. Brown dry spots are caused by underwatering.
