Latin name of the genus and species: Sansevieria trifasciata.
Variety denomination: ‘HANSOTI57’.
The present invention relates to a new and distinct cultivar of Sansevieria plant, botanically known as Sansevieria trifasciata, of the family Asparagaceae, hereinafter referred to by the cultivar name ‘HANSOTI57’.
Sansevieria is a monocotyledonous plant with fleshy, succulent leaves which are available in a huge range of species, varieties and cultivars as an outdoor ornamental plant (under tropical conditions) or as indoor plants.
The new Sansevieria ‘HANSOTI57’ was discovered and selected by the inventor, Ashish Hansoti, in early to mid-2020, as a single aberrant shoot arising from a plant of Sansevieria trifasciata ‘Hansoti20’, U.S. Plant Pat. No. 30,342, at a nursery in Village Vangani, District Thane, Maharashtra State in Western India. This shoot was cut out and rooted and allowed to grow and give pups—only pups with the same characteristics of the parent were selected.
Asexual reproduction in good numbers of the new, relatively stabilised Sansevieria cultivar ‘Hansoti57’ by vegetative cuttings was started in April or May 2021 at Village Asle, District Satara, Maharashtra State in Western India and it was seen that, after a few more rounds of discarding of off-types, the distinctive combination of characteristics of the new cultivar reproduced true to type as long as the propagation was done through side shoots (basal suckers) originating from the base of the parent plant. Thus, it can be said that the new cultivar reproduces true to type through side shoots (basal suckers)
The following traits have been repeatedly observed and are determined to be unique characteristics of ‘HANSOTI57’, which in combination distinguish this Sansevieria as a new and distinct cultivar:
The new variety ‘HANSOTI57’ is considered a variety of Sansevieria in the group denominated as the “Compact Sansevieria Group”. The new variety presents an average of 7 to 9 leaves per plant when it reaches its saleable size (between 3 to 4 months from rooted liner). The new variety has a semi-erect growth habit and the entire plant can reach a height ranging between 20 and 25 cm. The leaves are of medium width (5 to 7 cm) measured at the widest part of the mature leaf under good growing conditions) and broad-lanceolate with a firm, waxy texture. The blades are thick or fleshy and slightly wavy. This variety also has an inverted triangle shape like most Sansevieria of the Compact Group.
The new variety is moderately drought tolerant and adapts well to conditions of bright light and moderate shade (exterior and interior).
Overall, the new variety shows a bright variegated appearance with each leaf having three distinct longitudinal bands along each leaf—the dark grey-green marginal bands of 2 to 15 mm and occasionally up to 25 mm wide along the outer edge; a broad central grey to grey-green band of striations overlaid to varying degrees by a layer of grey-cream and a bright creamy green area between these two.
Superimposed on the whole leaf is the typical S. trifasciata cross banding—this is prominent on the dark edge bands but also somewhat visible on the central broad band and very indistinct and barely visible on the base creamy-green areas between the edge and central band.
The marginal band along each edge of the leaf is darker grey-green, varying in width from just 2 mm to 12 mm and may be as wide as 15 mm. These marginal bands have prominent horizontal cross banding of light and dark grey-green, as is common in most Sansevieria trifasciata cultivars. The two colors in this band are near RHS Greyed-Green 189A and N189A.
The central area of the leaf has a wide band of various shades of grey to grey-green striations, all covered with and veiled by a thin layer of creamy grey tissue. The depth of the grey overlying tissue determines the color of these central bands-from a dark green near RHS Greyed-Green N189A to a lighter 191A or even a very light 190C.
Between these two distinct border bands is a narrow area of creamy-green. This creamy-green zone is occasionally invaded by varying amounts of bright green streaks.
The creamy-green area between the marginal and central bands therefore varies from a very narrow zone 2 mm to 10 mm wide. The color of this bright creamy-green zone is near RHS Yellow-Green 150C or N144B and lighter creamy-green zone is near 154D.
What is important to the overall look of each leaf and the whole plant is the strong contrast between the dark green border bands and this creamy green and grey-green central zone—the plant look very highly variegated and richly colored compared to other, more traditional Sansevieria in the “Compact Sansevieria Group”.
Backside of the leaves is essentially the same coloring and pattern as the front with prominent dark grey-green marginal bands but somewhat narrower than on the front—typically 1 to 8 mm wide. The central band is also subdued and the creamy green tends to predominate—the overall look is a creamy green to grey-green central zone between the marginal dark green bands. On the back side of the leaf the typical S. trifasciata cross hatching is more visible, more prominent on the edge green bands but obvious even on the creamy areas.
Plants of the new Sansevieria ‘HANSOTI57’ are similar to plants of the parental cultivar, however, ‘HANSOTI57’ differs in the characteristics described in Table I.
In brief, the new ‘Hansoti57’ presents a different color palette-grey-green and lemon yellow—compared to the overall much more golden yellow parent.
The variety ‘Hansoti20’ gave rise to the variety ‘Hansoti57’. ‘Hansoti20’ shows somewhat less vigour than ‘Hansoti57’, typically has fewer leaves per plant (6 to 8 leaves), with a somewhat broader and shorter leaf with an average leaf width of 6 to 7 cm (measured in the middle of the mature leaf.) The growth habit is semi-erect and presents wider leaves supported in a rosette. The entire plant can reach a size from 20 to 25 cm. The plant has, as for ‘Hansoti57’, an inverted triangle shape. The leaves are broad-lanceolate with a waxy texture.
In comparison, ‘Hansoti57’ presents as a somewhat less creamy plant: the central light grey-green central band with greyish overlay is wider and the marginal bands (2 to 15 mm wide), are prominent, dark, grey-green also encroach on the cream area. These two together considerably restrict the cream area compared to the same in ‘Hansoti20’. The number of leaves are also more (typically 7 to 9 leaves)
This overall difference in the amount of green in the leaf gives a distinctly different look from the parent while also increasing the cultivars growth speed and its overall vigor.
Plants of the new Sansevieria ‘HANSOTI57’ are similar to the commercial variety Sansevieria trifasciata ‘Futura Superba’, unpatented. Plants of the new Sansevieria ‘HANSOTI57’ differ from plants of the commercial cultivar in the characteristics described in Table II.

The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘HANSOTI57’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describe the color of ‘HANSOTI57’.
These pictures illustrate the plant form which is the unique characteristic of ‘HANSOTI57’ and at the same time demonstrates that plant coloration and variegation pattern is similar to several other Sansevieria trifasciata cultivars. All plants were grown in an open poly house (high tunnel) at Village Asle, District Satara, Maharashtra State in Western India. Average temperature in Asle is 25° C. with summer highs of 39° C. and winter lows of 6° C. Plants grow under natural light conditions and between 30% to 75% shade levels depending on the season (higher shade in hot summer conditions). These conditions closely approximate those used in commercial practice in India.
The new Sansevieria ‘HANSOTI57’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, fertilizer levels and composition and day length without any change in the genotype of the plant.
The aforementioned photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar ‘HANSOTI57’ plants grown in an open poly house (high tunnel) at Village Asle, District Satara, Maharashtra State in Western India. Average temperature in Asle is 25° C., with summer highs of 39° C. and winter lows of 6° C. Plants grow under natural light conditions and between 30% to 75% shade levels depending on the season (higher shade in hot summer conditions).
This crop gets nearly constant fertilization to increase production. Controlled release fertilizer 13:11:11, type 360-days release at 1 kilo/cubic meter of media, constant liquid feed at approximately 100 ppm N, 20 ppm P and 100 ppm K, along with complete micronutrients. Production is closely related with proper and complete plant nutrition and an open soilless growing media based on coconut coir. The plants are grown in plastic pots on metal benching in spacing trays.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), (April 2009) except where general colors of ordinary significance are used.
The photographs and descriptions were taken during the winter season in Asle, District Satara, Maharashtra State, India when outdoor day temperature was 25° C. to 30° C. and cool nights, usually of 10° C. to 15° C. The age of the plants described is 3-4 months from rooted liners.
