Sansevieria genus is belong to Asparagaceae family, covers approximately 70 species, indigenous to Africa, Arabia, and India. Several species and their cultivars are grown commercially for use as interior foliage plants. The genus name Sansevieria originates from that of Raimond de Sangro, the prince of Sanseviero. He was a faithful patron of horticulture in Italy during the 18th century. The specific epithet trifasciata means three bundles.

Sansevierias are succulent plants, they have strong, plastic-like, succulent leaves that erupt right out of the ground from the roots or rhizomes. They have no stems. Flowers in summer or autumn. Flowers are whitish to pale yellow-green and some are nicely scented. Flowered plant will no longer produce new leaves but will continue to grow by producing plantlets via its rhizomes or stolons. Many species, are naturally variegated being banded, striped or mottled to varying degrees. Some have thin, flat, upright leaves while others have nearly cylindrical, arching or straight, spear-like leaves that end in sharp points. The leaves of Sansevieria are typically arranged in a rosette around the growing point, although some species are distichous. There is great variation in foliage form within the genus. All species can be divided into one of two basic categories based on their leaves: hard leaved and soft leaved species. Typically, hard leaved Sansevieria originate from arid climates, while the soft leaved species originate from tropical and subtropical regions.

There are around 130-140 species and cultivars of Sansevierias. Many of the cultivars are variegated forms and there are over 60 cultivars of Sansevieria trifasciata alone. Cultivars of Sansevierias divided three groups: normal full size, medium size with wide leaves and small (dwarf) size.

Sansevierias are succulent plants so need a well-drained compost and moderate watering. In the summer months they can be watered frequently and appreciate this, as long as the soil does not remain water-logged, but in the cooler months they should left dry. A minimum winter temperature of 10°C is recommended. They withstand short periods of light freeze as long as the plants are dry.

Sansevierias are difficult to keep in captivity as they always try to escape. Most spread through underground rhizomes. They can be propagated by cuttings or by dividing the rhizome. Cuttings have the disadvantage that the variegation will be lost. Plants can also be produced from seed although this is a slow process.

SANSEVIERIA TRIFASCIATA, MOTHER-IN-LAW’S TONGUE has up to 6 leaves per rosette. Mature leaves are dark green with light gray-green cross-banding, 70–90 cm long and 5–6 cm wide. Ultimate height is 100-150 cm. Numerous cultivars have been selected, many of them for variegated foliage with yellow or silvery-white stripes on the leaf margins. Popular cultivars include ‘Compacta’, ‘Goldiana’, ‘Hahnii’, ‘Laurentii’, ‘Silbersee’, and ‘Silver Hahnii’. A variegated cultivar of Sansevieria trifasciata ‘Laurentii’, the most common species in cultivation.

SANSEVIERIA CYLINDRICA–SPEAR SANSEVIERIA is native to Angola. It has a thick rhizome supporting rosettes of 3 to 4 leaves, each 80 to 130 cm long by 1 to 3 cm wide. The medium green leaves with dark green cross-banding are nearly cylindrical and slightly thicker from front to back than from side to side.

SANSEVIERIA GRANDIS is known by the common name Somali Hemp. It grows quickly to an average mature height of 50 cm and a width of 30 cm.–GENİŞ YAPRAKLI PAŞA KILICI  Doğal olarak, Yemen, Sudan, Ethiopia ve Kenya’da bulunmaktadır. Yaprakları sert, desenli, geniş ve kısadır. Koyu yeşil renk yaprakların kenarları hafif kırmızı renktedir.

Use in Landscape: It is popular as a houseplant because it is tolerant of low light levels and irregular watering, during winter it needs only one watering every couple of months. It will rot easily if overwatered.  Indoors they may be used in floor level planters, small specimens, dish gardens and other combination planters, and occasionally in hanging planters.

A study by NASA found that it is one of the best plants for improving indoor air quality by passively absorbing toxins such as nitrogen oxides and formaldehyde. Like the Golden Pothos (Epipremnum aureum) and Corn Plant (Dracaena fragrans), Sansevieria species are good air purifiers by removing toxins (such as formaldehyde, xylene and toluene) from the air, Sansevieria use the crassulacean acid metabolism process, which absorbs carbon dioxide and releases oxygen at night. This purportedly makes them suitable bedroom plants. However, since the leaves are potentially poisonous if ingested, Sansevieria is not recommended for children’s bedrooms.
