Abstract

A new and distinct Haworthia cultivar named ‘AMSTERDAM’ is disclosed, characterized by a small number of leaves per plant, and unique small white spots on the leaves. The new variety is a Haworthia, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Haworthia fasciata.

Variety denomination: ‘AMSTERDAM’.

BACKGROUND OF THE INVENTION

The new Haworthia cultivar is a product of a planned breeding program conducted by the inventor, Rogier Willems, in Tielen, Belgium. The objective of the breeding program was to produce new Haworthia varieties for ornamental commercial applications. The cross resulting in this new variety was made before 2008, exact date unknown.

The seed parent is a unpatented, unnamed, proprietary seedling variety of Haworthia fasciata. The pollen parent is unknown, as the crossing resulting in ‘AMSTERDAM’ was an open pollination, with unidentifiable pollen parents. The new variety was discovered in July 2008 by the inventor in a group of seedlings resulting from the crossing, in a research greenhouse in Tielen, Belgium.

Asexual reproduction of the new cultivar ‘AMSTERDAM’ by tissue culture and vegetative cuttings was first performed at a research greenhouse in Tielen, Belgium in July 2008 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘AMSTERDAM’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AMSTERDAM’ These characteristics in combination distinguish ‘AMSTERDAM’ as a new and distinct Haworthia cultivar:

    • 1. Small quantity of leaves.
    • 3. Small white dots on leaves

Plants of the new cultivar ‘AMSTERDAM’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘AMSTERDAM’ produce white on the inside of the leaf, whereas the seed parent does not. ‘AMSTERDAM’ also has less leaves than the seed parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘AMSTERDAM’ are similar to plants of the commercial variety of Haworthia fasciata known as ‘Concolor’, unpatented in most horticultural characteristics. However, plants of the new cultivar ‘AMSTERDAM’ produce leaves with more white spots on leaf overall, as well as larger white spots on leaves, compared to ‘Concolor’. ‘AMSTERDAM’ also has fewer leaves than ‘Concolor’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘AMSTERDAM’ grown in a greenhouse, in a 8.5 cm pot. Age of the plant photographed is approximately 18 months from a rooted cutting. 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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2005 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘AMSTERDAM’ plants in a greenhouse in Tielen, Belgium. The growing temperature ranged from 18° C. to 28° C. during the day and from 13° C. to 18° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types. Plants are approximately 18 months old from a rooted cutting.
