Sansevera (Sansevieria, sansevieriya) differs understated but alluring beauty of the dense, collected in a bunch of decorative leaves that moved up or divergent in hand; it is surprisingly elegant and remarkably unpretentious.
For the shape and coloring of leaves Sansevera is popularly called "snake tail", "ragged tail", "Teschin language"; English call - "leopard lily", "devil's tongue", "snake plant"; Americans call - "snake skin"; Germans call for fibrous sheet - "African hemp". Vitality, beauty and simplicity leaves sansevery reproduction provided her widespread and increasingly popular in the culture room.
Sansevera (Sansevieria) - evergreen stemless plant family Dratsenovye. The Latin name of the genus comes from the name sansevera Neapolitan Prince von Sansevieria, which contributed to the development of the natural sciences. In nature sansevery grow in savannas, semi-deserts and tropical regions of Africa and Asia - are 70 of its species.
In some species the leaves are covered with characteristic Sansevera succulents thin wax coating that protects them from moisture evaporation. At home sansevera used for fabrics, ropes, and growing as a hedge. Fiber leaves sansevery walked among the natives for the manufacture of bows for string, so Sansevera also called arc.
Sansevera has an underground creeping rhizome with rigid basal leaves - dark green, gray-green, speckled due to whitish and dark green stripes, creating transverse bands. Rhizome sansevery has strong rhizomes that can break the pot. Greenish-white flowers with narrow petals and long stamens, in dense cylindrical inflorescence on a long erect spike, very fragrant - disclosed in the evening and at night emit a strong vanilla flavor. Flowers and inflorescence branches isolated drops of nectar that attracts nature insect pollinators.
Sansevera from the XVIII century is grown in Europe as a Decorative leef plants. A variety of garden forms sansevery successfully used for landscaping spaces and winter gardens, creating large composite arrangements.
In room culture are more likely to grown species:
- Sansevera trÑ‘hpolosaya or guinea (S. trifasciata) with sword-shaped, slightly concave, pointy leaves - light green with dark green stripes. There are tall (one meter) and dwarf (20 cm) species sansevery trÑ‘hpolosoy - forms Lawrence and Haniya; their grades are remarkable especially decorative leaves (with yellow edges, belopÑ‘strymi, golden-striped). Impressive belopolosataya species has on the leaves pure white longitudinal stripes of different widths.
- Sansevera graceful (S. gracilis) with green cylindrical leaves;
- Sansevera cylindrical (S. cylindrica) with dark green cylindrical tubular-constricted leaves;
Sansevery other species grown in culture room, also varied: sansevera large (S. grandis) - large trees with dense oblong-oval leaves; sansevera Duneri (S. dooneri) - miniature with lots of outlets. Dwarf sansevery remind haworthias.
Sansevera grows best in light (from the sun to poluzatenennyh), warm rooms (not below 15 degrees). Variegated leaves sansevery lose bright picture and decorative low-light (and pereudobrenii). But we need to protect the plant from the bright, hot sun (especially in spring), causing burns on the leaves. Sansevera easily tolerates dry air and lack of water, the presence of lime in the water.
Watering in the summer of regular and moderate, but not abundant and only after drying of the substrate; winter, reduce watering to a minimum (with excess watering and rhizome rot sansevera loses leaves). Water during irrigation should not fall into the center of the outlet. At higher humidity, and lack of light on the leaves appear sansevery cortical spots. It is useful to periodically wash the leaves sansevery soft damp sponge dipped in warm water; loosen the soil surface.
Sansevera transplant (young plants - year old - at least, if necessary) into the low wide pots with good drainage; substrate is made from a mixture of leaf and sod land with sand (4: 2: 1), with the addition of peat and humus. This is one of the best plants for hydroponics. Sansevera fertilized in May and throughout the summer, 2 times a month, in the rest of the year 1 time per month - paid fertilizer for cacti or a complete fertilizer.
Sansevera propagated by division of rhizomes and leaf cuttings. Variegated varieties sansevery to preserve color propagated only by division of rhizomes. The leaves are cut into pieces about 10 cm long, powdered with slices pounded charcoal and planted obliquely in pots with damp sand, sunk with 2 cm; rooting at room temperature (not below 22 degrees) occurs in a month and a half.
Cut leaves for decoration compositions sansevery after a long standing in the water are also used for breeding. Sansevera may be affected by spider mites and scale insects.
