Abstract
A new and distinct Haworthia plant named ‘AMIHAW1801’, which is characterized by a fast rate of growth, succulent foliage that is held upright in a spirally-arranged rosette, large, broadly deltoid foliage with coarsely dentate margins, and dark green foliage which is tolerant of high light levels. The new variety has shown to be uniform and stable in the resulting generations from asexual propagation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Haworthia pentagona.
Variety denomination: The inventive variety of Haworthia plant disclosed herein has been given the variety denomination ‘AMIHAW1801’.
Parentage: ‘AMIHAW1801’ originated as a naturally occurring, whole-plant mutation of an unnamed Haworthia pentagona plant (not patented). In September of 2013 the inventor discovered the mutation at a commercial greenhouse in Heerhugowaard, the Netherlands, growing amongst a crop of the species Haworthia pentagona. The mutation was noted for its improved vigor and dark green, broad deltoid foliage and was subsequently isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘AMIHAW1801’ was selected for commercialization.
Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIHAW1801’, by way of rooting leaf cuttings, was first initiated in March of 2014 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through eight subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The cultivar ‘AMIHAW1801’ 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 ‘AMIHAW1801’. These characteristics in combination distinguish ‘AMIHAW1801’ as a new and distinct Haworthia cultivar:
-
- 1. ‘AMIHAW1801’ exhibits spirally-arranged succulent foliage, held upright, in a basal rosette; and
- 2. ‘AMIHAW1801’ exhibits a fast rate of growth; and
- 3. ‘AMIHAW1801’ exhibits large, broadly deltoid foliage with prominent teeth that are moderately abundant along the proximal half of the leaf margin and become less prominent and nearly absent towards the distal portion and apex; and
- 4. ‘AMIHAW1801’ exhibits dark green foliage which is tolerant of high light levels.
The following observations and measurements made in January of 2017 describe averages from a sample set of six specimens of 7.5 months old ‘AMIHAW1801’ plants grown in 12 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Haworthia plants which consisted of minimal subsurface irrigation and minimal fertilizer applications, and chemical pest and disease control measures against mealy bug, Botrytis sp. and Fusarium sp. as required. Plants were grown under approximately 50 percent shade and no photoperiodic treatments or artificial light was given to the plants.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIHAW1801’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
