There are several different kinds of Sansevierias, but the most popular is Sansevieria Trifasciata Laurentii. This plant has tall, spiky leaves with black markings in the centre and a yellow stripe at the edge. To maintain the yellow stripe, propagation must be by division.
Water once a week in Summer and every 3 weeks in Winter. Never over water the plant.
Apply an all purpose fertilizer at half strength monthly from Spring to Autumn.
Re-pot when the plant breaks the pot in which it is growing. Add 1/3 of perlite and 2/3 of soil-based potting mixture and put some clay pot pieces into the bottom of the pot.
Cut out 8 inches offshoots with rhizome in Spring to mid Summer and pot in cactus and succulent compost. The green species can be propagated from leaf cuttings 2 inches sections across the leaf.
Keep Sansevieria in warmth, on the dry side and in good light.
Sansevieria is useful to clean indoor air pollution.
It grows better when it is pot-bound. Sponge the leaves once a month with tepid water.
It is useful in centrally heated rooms. It is also suitable for dining rooms, lounge or office.
Sansevieria likes dry atmosphere. Do not spray.
Most plant cells look like little boxes full of green disks. The disks are called chloroplasts. Other organelles inside a plant cell include a nucleus (where the DNA is kept), a large central vacuole (where water and other materials are stored) and a complex internal skeleton or cytoskeleton made of various proteins.
