Can go for long periods of time with out water, but prefers to be kept evenly moist to slightly dry. One time I forgot about 3 plants in the north window of a room, for 2 months. They never got watered and are still alive today. Not a recommended practice!
Soil & Site
average, well drained
Growing Media
average house
Temperature
average house
Flowers
not know to flower
Leaves
vase-shaped rosette of dark green leaves with banding patterns
Dimensions
The plant is made up of rosettes of leaves. I have had them fill out 12" pots and I assume they will even fill out larger containers. Can be kept to smaller pots by dividing the plants as needed.
Maintenance
Very little is needed just occasional re-potting when the plants get to large. They have very strong rhizomes and will crack almost any pot
Propagation
The easiest and most common way is by division. Just knock the plant out of the pot and divide into section. Most of the plants will root from partial leaf cuttings which is a leaf cut into sections and rooted. The draw back to this method is, if the plant is a sport (genetic variation) it will revert back to its parent plant. I have rooted Futura and Golden Snake plant from partial leaf cuttings and they both have reverted back to S. trifasciata. I have rooted S. trifascita and S. cylindica and they have come true from the partial leaf cutting
Cultivar Origin
Birdnest sansevieria, a sport of S. trifasciata `Laurentii', was discovered by William W. Smith, Jr. in the Crescent Nursery Company, New Orleans, Louisiana in 1939 and was patented in 1941. The patent was assigned to Sylvan Hahn, Pittsburgh, Pennsylvania USA
