<i>Sansevieria </i>plant named ‘HANSOTI21’

Abstract

A new and distinct cultivar of Sansevieria plant named ‘HANSOTI21’ 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 yellow margin. The new variety is a Sansevieria, typically produced as an indoor ornamental plant.

Claims

1. A new and distinct cultivar of Sansevieria plant named ‘HANSOTI21’ as herein illustrated and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs illustrate the overall appearance of the new Sansevieria cultivar ‘HANSOTI21’ 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 ‘HANSOTI21’.

(2) These pictures illustrate the plant form which is the unique characteristic of ‘Hansoti21’ 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.

(3) FIG. 1 shows a four-month-old plant of Sansevieria ‘HANSOTI21’ in a 12 cm diameter pot.

(4) FIG. 2 shows a top view of a plant of ‘HANSOTI21’ showing clearly the spiral formation of the leaves.

(5) FIG. 3 shows a tray holding 6 ‘HANSOTI21’ plants in 12 cm pots showing uniformity across multiple plants of this new cultivar.

(6) FIG. 4 shows ‘HANSOTI21’ besides the parent plant, Sansevieria ‘Green Compacta’. The parent plant is on the left, the new variety on the right. Note the flattened presentation of the ‘HANSOTI21’ rosette even when compared to the compact parental ‘Hahnii Green Compacta’.

(7) FIG. 5 shows a plant of ‘HANSOTI21’(on left) in a 12 cm pot side by side with a plant of closest comparable cultivar, ‘Dragon Tongue’(on right) in a 13.5 cm pot.

(8) FIG. 6 shows individual leaves of Sansevieria ‘HANSOTI21’ (on left) compared to individual leaves of Sansevieria ‘Dragon Tongue’ (on right). Illustrated is the substantial difference in size and curvature pattern with ‘Dragon Tongue’ leaves, which are much bigger than leaves of ‘HANSOTI21’.

DETAILED BOTANICAL DESCRIPTION

(9) The new Sansevieria ‘HANSOTI21’ 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.

(10) The aforementioned photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar ‘HANSOTI21’ 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).

(11) This crop gets nearly constant fertilization to increase production Constant Liquid Feed at approximately 150 ppm N, 30 ppm P and 150 ppm K is used along with 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

(12) 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.
