plant named ‘HANSOTI41’

A new and distinct cultivar of Sansevieria plant named ‘HANSOTI41’ is disclosed, characterized by unusual twisted, curled, compact foliage arranged in flattened, spiral rosettes. The new cultivar is a compact Birds Nest type Sansevieria forming small plants, reaching only about 12 cm in height at maturity. Plants require little water, having a moderate tolerance for drought, and are also tolerant of very wet conditions. Foliage is green and yellow-green banded with a dark-green margin. The new variety is a Sansevieria, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Sansevieria trifasciata.

Variety denomination: ‘HANSOTI41’.

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 ‘HANSOTI41’.

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 ‘HANSOTI41’ was discovered and selected by the inventor, Ashish Hansoti, as a single aberrant side shoot within a planting of Sansevieria trifasciata ‘Hahnii Gold’, a non-patented ‘Hahnii’ or ‘Birds Nest’ type of Sansevieria grown at a nursery in Village Vangani, District Thane, Maharashtra State in Western India. ‘HANSOTI41’ originated as a naturally-occurring mutation of the Sansevieria trifasciata variety ‘Hahnii Gold’, unpatented, in early 2018.

Asexual reproduction of the new Sansevieria cultivar by vegetative cuttings was first performed in March 2019 at a commercial nursery in Village Vangani, District Thane, Maharashtra State in Western India. This first and subsequent propagation have shown that the distinctive combination of characteristics of the new cultivar are reproduced true to type as long as the propagation was done through side shoots (basal suckers) originating from the base of the originally discovered 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 ‘HANSOTI41’, which in combination distinguish this Sansevieria as a new and distinct cultivar:

    • 1. Twisted, curved leaves forming a relatively flat, somewhat open spiral-form rosette that stays vertically compact and gives a vertically compressed appearance as opposed to most other Sansevieria trifasciata ‘Hahnii’ cultivars where the leaves are more or less straight and more vertically oriented. The spiral rosette often is somewhat asymmetrical when seen from top. Total mature-plant width in a 12 cm pot is 15 to 17 cm and height above the pot is only 6 to 8 cm.
    • 2. Leaf coloration and variegation pattern is also quite unique and very different from its parent, Sansevieria trifasciata ‘Hahnii Gold’. Overall colour impression is of an olive green Sansevieria with streaks of cream and greyish green.

‘HANSOTI41’ has foliage variegation that is unlike its parent or, indeed, any other Hahnii, know to the Inventor, type along with the very unusual vertically-flat spiral foliage arrangement, asymmetrical when seen from top, giving an overall extremely distinctive and unique appearance.

Leaf width is somewhat variable and the strongest, healthiest plants have the widest leaves (this is true across all Sansevieria trifasciata cultivars known to the inventor) though leaves in ‘HANSOTI41’ are relatively narrow. This variation means leaf width can be anything from 3 cm to 4 cm wide depending on season, growing conditions and plant vigour and plant age. Typically, the leaves are of medium width (5 cm average measured at the widest part of the mature leaf under good growing conditions) and 12-16 cm long, ensiform but not erect; rather, most unusually, they are held almost perfectly horizontally. Leaves have a firm, waxy texture. The blades are thick and fleshy.

The new variety ‘HANSOTI41’ is a variety of Sansevieria in the group denominated as “Birds Nest” or ‘Hahnii’ types based on its origin and overall plant form. The new variety presents an average of 12 leaves per plant when it reaches its saleable size (about 3 months from rooted Liner) but over time it can grow and accumulate many more leaves and increase in overall height.

The new variety is moderately drought tolerant and adapts well to conditions of bright light or heavy shade (exterior and interior). The intensity of leaf colour varies with exposure to light and the contrast is most intense under higher light conditions.

The leaves show a variegated colouration, with broad green borders having a central area of cream liberally interspersed with grey-green streaks. The typical Sansevieria trifasciata cross hatching along the width of the leaf is distinctly seen. The amount of cream colour is variable but generally it is overwhelmed by the darker green longitudinal bands. Younger leaves, side shoots and plants tend to show more creamy coloration. Older leaves are darker green.

Each leaf has a marginal deep green band similar to RHS Yellow-Green N189A and varies in width from just 3 mm to 15 mm. Within this dark olive-green border is creamy coloration close to Yellow 160A, overlaid to varying degrees (but covering most of the centre of each leaf) with streaks similar to Grey-Green 191C and occasional darker green streaks of Yellow-Green 189B.

The backside of the leaves is also distinctive—a relatively thin 1 mm to 10 mm wide border of dark olive green with a visually uniform creamy coloration between these dark borders with the grey-green pattern of the top of the leaf showing in the depths below this cream layer. The backside of the leaf also has the typical Sansevieria trifasciata transverse banding but this banding is light and indistinct—near RHS Yellow-Green154B interspersed with transverse bands similar to but somewhat lighter than Yellow 2D—observable only on close inspection.

Attached colour pictures are a better guide to the complex leaf arrangement and the overall colouration and variegation pattern rather than written descriptions and are the best reference to compare the new plant invention ‘HANSOTI41’ to older and newer Sansevieria trifasciata ‘Hahnii’ mutants. The primary distinctive characteristics of ‘HANSOTI41’ are the curved, twisted leaves forming a flat, vertically compact disc and the atypical variegation colour and pattern of these twisted leaves.

PARENTAL COMPARISON

Plants of the new Sansevieria ‘HANSOTI41’ are similar to plants of the parental cultivar, however, ‘HANSOTI41’ differs in the characteristics described in Table 1.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘HANSOTI41’ 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 ‘HANSOTI41’.

These pictures illustrate the plant form which is the unique characteristic of ‘HANSOTI41’ 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.
