Sansevieria plant named ‘Black Limón’

Abstract

The new variety Black Limón is part of the “long leaves” group of Sansevieria varieties and is a naturally-occurring mutation of the Sansevieria trifasciata variety ‘Laurentii’. It can reach 50-80 cm in length, with an average of approximately 3-5 leaves per plant. The plant is cylindrically shaped, with an erect growth habit and the arrangement of the leaves is in the form of a rosette. The new variety shows coloration very different from its parent variety and has variegated green leaves with light yellow-green colored margins. The new variety needs little water and is very drought tolerant.

DETAILED BOTANICAL DESCRIPTION

(5) The new Sansevieria ‘Black Limón’ 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 ‘Black Limón’ as grown in open-field conditions at Monterrey, San Carlos, Alajuela province, Costa Rica, under conditions which closely approximate those generally used in commercial practice. 24.5° C. during the day and 18° C. at night.
