plant named ‘Green Star’

Abstract

A new cultivar of Gasteria plant named ‘Green Star’ that is characterized by an upright habit and green leaves with light green spots.

Description

Botanical classification: Gasteria hybrid.

Variety denomination: ‘GREEN STAR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gasteria plant botanically known as Gasteria hybrid and hereinafter referred to by the cultivar name ‘Green Star’.

‘Green Star’ was discovered as a naturally occurring whole plant mutation of Gasteria hybrid ‘WT03’ (not patented). ‘Green Star’ was discovered in July of 2010 as a single plant in a population of Gasteria ‘WT03’ plants grown from tissue culture in a greenhouse in a cultivated area of Swellendam, South Africa.

Asexual reproduction of the new cultivar ‘Green Star’ first occurred by tissue culture in November of 2010 in Swellendam, South Africa. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Gasteria cultivar ‘Green Star’. These traits in combination distinguish ‘Green Star’ as a new and distinct cultivar apart from other existing known varieties of Gasteria.

• • 1. Gasteria ‘Green Star’ exhibits an upright habit.
  • 2. Gasteria ‘Green Star’ exhibits green leaves with light green spots.

The closest comparison cultivar is the parent plant Gasteria ‘WT03’. Green Star’ is distinguishable from ‘WT03’ by the following characteristics:

• • 1. Gasteria ‘Green Star’ exhibits a more upright habit than ‘WT03’. The habit of ‘WT03’ is more spreading.
  • 2. Gasteria ‘Green Star’ exhibits leaves that are lighter green in color than the leaves of ‘WT03’.
  • 3. Gasteria ‘Green Star’ exhibits leaves with green spots. In comparison, the leaves of ‘WT03’ have white spots.
  • 4. Gasteria ‘Green Star’ exhibits a faster growth rate than ‘WT03’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Gasteria ‘Green Star’. The plant in the photograph shows an overall view of an 18 month old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Gasteria cultivar named ‘Green Star’. Data was collected in Tielen, Belgium from 18 month plants grown in a glass greenhouse in 13 cm. diameter containers. The time of year was December and the temperature range was 12-22 degrees Centigrade during the day and 12-22 degrees Centigrade at night. The light level was natural light. No photoperiodic treatments or growth retards were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Green Star’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
