Description

Latin name of the genus and species: Sansevieria trifasciata.

Variety denomination: ‘HANSOTI59’.

BACKGROUND OF THE INVENTION

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 ‘HANSOTI59’.

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 ‘HANSOTI59’ was discovered and selected by the inventor, Ashish Hansoti, as a naturally-occurring mutation from an aberrant Sansevieria trifasciata ‘Black Moon’ (an unpatented cultivar selected and grown by the Inventor) in 2018, at a nursery in Village Vangani, District Thane, Maharashtra State in Western India.

Asexual reproduction in good numbers of the new, relatively stabilised Sansevieria cultivar ‘HANSOTI59’ by vegetative cuttings was started March-April 2020 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)

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘HANSOTI59’, which in combination distinguish this Sansevieria as a new and distinct cultivar:

    • 1. Foliage variegation in the form of linear bands and streaks of different grey-greens and creams along the length of the leaf, a dark green leaf border and a golden yellow suffusion towards the base of the leaf.
    • 2. Unusually upright, relatively narrow leaves giving a particularly vertically oriented narrow rosette of greyish-green to cream-streaked leaves. Such a vertical rosette makes for a potted plant that's easier to handle and easier to pack.
    • 3. Slowly changing of the variegation pattern and color of new leaves as more leaves emerge from an older plant to give a creamier look as the plant ages. Overall ‘Hansoti59’ is one of the more colorful Sansevieria hybrids known to the inventor.
    • 4. Changing color and variegation pattern of newly emerging leaves with increasing plant age-leaves in a young plant (3-5 months from rooted liner) are typically grey-green with a thin 1 to 3 mm green outer edge and a white to cream inner border of 1 to 3 mm width. Basal ⅓rd of each leaf is suffused with yellow while the top ⅔rd lacks this suffusion and is more grey-green. As the plant ages and matures, the new leaves emerge with increasing amounts of yellow-cream colored variegation, with an enhanced dark green border varying from 1 to 10 mm wide and a central band of green streaks overlaid with yellowish cream to varying degrees. This variability in the plant coloring is standard and stable in this cultivar and all plants in a bench of ‘Hansoti59’ exhibit this variation and change in color.
    • 5. At 20-25 cm plant height overall, this is one of the cultivars with shorter leaves but still exhibits average height due to the straight leaves and their vertical orientation, an unusual trait amongst the Sansevieria trifasciata cultivars nominated as “Compact Sansevieria Group”.
    • 6. Ready to sell, 3-month (from rooted liner) old plants have 7-9 leaves per plant which is relatively high compared to other Sansevieria in the Compact Group, which at this age have 4-6 leaves. This gives a more bushy, full plant compared to other Sansevieria in the Compact Group.

The new variety ‘HANSOTI59’ 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 (4 to 5 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 but the whole rosette is narrower and more vertical rather than spreading compared to other cultivars.

The new variety is moderately drought tolerant and adapts well to conditions of bright light and heavy shade (exterior and interior).

Describing the leaf is more than usually difficult as the leaves in young plants (3-6 months old) are significantly different compared to leaves that emerge from the same plant subsequently, when the plant is older than 4-5 months (from rooted liner). To a large extent the leaves that will be seen in commercial cultivation and sale of this cultivar will be the grey-green leaves of younger plants.

The overall impression is of a grey-green leaf with longitudinal striations in light grey and grey-green. A closer inspection reveals a white border along the outer edge and a dark green line along the outermost edge of the leaf.

The dark green edge is close to RHS Green 139A and the white border is similar to White 155B. The longitudinal lines and striations are similar to Greyed-Green N189B.

Another interesting aspect is the suffusion of yellow in the full lower ⅓rd to ½ of the leaf. This suffusion is close to RHS Yellow-Green 145A and is seen in leaves from plants of all ages.

Very young emerging shoots are obviously much paler with a whitish-cream color similar to but even lighter than RHS White 155A on inside of leaf and similar to Gray-Green 191C or 191D on the outside and a very pale background color of Yellow 2C. Marginal band is brighter green.

As the plant ages, the new emerging leaves change their variegation pattern substantially. The green edge becomes a green border 2 to 10 mm wide, its color close to RHS Green 139A. Within the two borders on either side of the leaf the amount of creamy-yellow increases substantially and can be seen as bands from 2 to 10 mm wide. These bands keep increasing in width till they almost cover the whole width of the leaf.

The lines of grey-green (close to RHS Greyed-Green N189B) persist for a few leaves but are more and more invaded by creamy-yellow streaks. Eventually, the most mature leaves are almost entirely creamy-yellow (Close to Yellow 3C and 4B) with just a few grey-green streaks in the centre, mostly veiled by a layer of cream epidermis.

Backside of the leaves is similarly colored with wide central darker band and thinned marginal bands. However, usually the whole of the backside of the leaf is more uniform due to thicker overlying layer of greyish cream (RHS Greyed-Green 189B) so that the darker vertical bands (Green N189B) are less distinct that on the front or top of the leaf.

PARENTAL COMPARISON

Plants of the new Sansevieria ‘HANSOTI59’ are similar to plants of the parental cultivar, however, ‘HANSOTI59’ differs in the characteristics described in Table I. Plants measured were approximately 6 months of age, unless otherwise noted.

Leaf Broad, stiff lanceolate leaf Narrower leaves, straight and shape in a wide rosette. more vertically held. 6. Vigor Very vigorous Somewhat less vigorous but still a strong grower.

A special selection from the variety ‘Black Moon’ gave rise to the variety ‘Hansoti59’. ‘Black Moon’, being almost entirely dark green, shows stronger vigor than ‘Hansoti59’ but has fewer leaves per plant (5-7), with a broader leaf with an average leaf width of 8-10 cm (measured in the middle of the mature leaf.) The growth habit is semi-erect and presents its leaves in a wide rosette. The entire plant can reach a size from 25-30 cm. The plant has, as for ‘Hansoti59’, an inverted triangle shape. The leaves are broad lanceolate with a waxy texture.

Overall, the plants of ‘Black Moon’ look dark green with no variegation but with prominent transverse banding so common in S. trifasciata cultivars while the specific, select parent plant had a single white stripe along one leaf. ‘Hansoti59’ presents very differently, as a variegated, much brighter, highly colored plant with stripes of creamy-grey, a wide green central band with greyish overlay and a brighter green, thinner marginal band and a suffusion of yellow on approximately the lower ⅓rd of the leaf. The overall bright coloration is striking and very unique amongst Sansevieria, most of them being much less colorful.

COMMERCIAL COMPARATOR

Plants of the new Sansevieria ‘HANSOTI59’ are similar to the commercial variety Sansevieria ‘Frozen’, U.S. Plant Pat. No. 29,345. However, ‘HANSOTI59’ differs in the characteristics described in Table II. Plants measured were approximately 6 months of age, unless otherwise noted.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar. ‘HANSOTI59’ 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 ‘HANSOTI59’.

These pictures illustrate the plant form which is the unique characteristic of ‘HANSOTI59’ 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.

FIG. 1: Shows an old photo of the mother plant (a selection from the old cultivar, S. trifasciata ‘Black Moon’) showing the leaf with a single white stripe and the first aberrant side shoot which was selected as ‘Hansoti59’. The mother plant is no longer in cultivation so contemporary photos are not possible.

FIG. 2, FIG. 3 and FIG. 4 show a saleable size plant of Sansevieria ‘Hansoti59’ in a 12 cm diameter pot at about 2.5 months old from various angles. The photos illustrate top as well as bottom of leaves and the leaf arrangement. FIG. 2 illustrates a view of a plant of ‘Hansoti59’ from about a 45 degree angle from the top. FIG. 3 illustrates the rather vertical leaf phyllotaxy.

FIG. 4, illustrates a view of ‘Hansoti59’ directly from the top of the pot showing the yellow effusion on the lower third of each leaf. This plant is approximately 2.5 years old.

FIG. 5 is a top down view of 6 plants of ‘Hansoti59’ at about 2 months of age, showing uniformity across multiple plants.

FIG. 6 is a view taken from an angle of about 45 degrees from the top of 6 plants of ‘Hansoti59’ at about 2 months of age, showing uniformity across multiple plants.

FIG. 7 is a side view of 6 plants of ‘Hansoti59’ at about 2 months of age, showing uniformity across multiple plants.

FIG. 8: Shows a plant of ‘Hansoti59’ (left side) next to a plant of a comparable cultivar S. trifasciata ‘Frozen’ (right side) to illustrate the similarities and differences.

FIG. 10: Shows individual leaves (abaxial surface) of ‘Hansoti59’ (top row) and the comparable cultivar S. trifasciata ‘Frozen’ (bottom row) side by side clearly illustrating the differences in variegation pattern and colors of the two cultivars.

FIG. 11: illustrates the variegation color change with age, showing 5 plants of ‘Hansoti59’ at different ages from 2.5 moths to 2 years. The bottom row, left side is a plant of 2.5 months old, bottom row right wide is a 4 month old plant. The top row, left side is a 10 month old plant, center 12 month old plant and the right side top row is a 2 year old plant. Emerging leaves get brighter cream variegation as they emerge from older plants. Leaves also spread out a little. This change is a standard and consistent characteristic across all plants of ‘Hansoti59’.

FIG. 12 shows a range of variegation pattern in individual leaves as plant ages. These are all from one plant at approximately 2.5 years old. Progressively older leaves showing how new leaves emerge with substantial change in variegation pattern and color; old leaf on right (which emerged when the plant was young) and progressively newer leaves as we go left (emerging from an older plant). Adaxial surfaces on top and abaxial surfaces of the same leaves in bottom row.

 DETAILED BOTANICAL DESCRIPTION

The new Sansevieria ‘HANSOTI59’ 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 ‘HANSOTI59’ 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 fertiliser of 13:11:11 Type 360-days release at 1 kilo/cubic meter of media, constant liquid feed at approximately 100 ppm N, 30 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 Color Chart (R.H.S.), (April 2007) 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 plant described is 3-4 months from rooted liners.
