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

Abstract

The new variety Spearmint is a type of long leaves Sansevieria plant. It can reach 80 cm in length, with an average of approximately 3-5 leaves per plant. The plant is cylindrically shaped, the arrangement of the leaves is in the form of a rosette. The leaf blade is greyed-green colored, with dark green colored non-uniform horizontal variegated bands in both sides of the leaves, and green margins. Shows colors very different from its parent variety Wintergreen (Patented, U.S. Plant Pat. No. 24,939), and Bantel Sensation (unpatented). Unlike its parent variety it shows variegated leaves (different green tones on the irregular bands) and Spearmint also presents less leaves per rosette.

DETAILED BOTANICAL DESCRIPTION

(5) The new Sansevieria Spearmint 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, and day length without any change in the genotype of the plant.

(6) The aforementioned photographs, together with the following observations, measurements and values describe the new Sansevieria cultivar Spearmint as grown in open-field conditions at Guatuso, San Carlos, Alajuela province, Costa Rica, under conditions which closely approximate those generally used in commercial practice. 28 C. during the day and 18 C. at night. Plants grow under natural light conditions. This crop does not require constant fertilization, to increase production per area about 200 kg ha1 N, 150 kg ha1 of P and 100 kg ha1 K are required, the production is closely related with soil conditions in which they are grown.
