Abstract

A new and distinct cultivar of Alocasia plant named ‘AARALZE001’, characterized by its compact, upright to outwardly arching and uniform plant habit; moderately vigorous growth habit; moderately rapid growth rate; dark green-colored leaves; and greyed green-colored petioles that are transversely marked with dark greyed green to black-colored marbling.

Description

Botanical designation: Alocasia zebrina.

Cultivar denomination: ‘AARALZE001’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alocasia plant, botanically known as Alocasia zebrina, common referred to as Elephant's Ear Plant and hereinafter referred to by the name ‘AARALZE001’.

The new Alocasia plant is a naturally-occurring whole plant mutation of an unnamed selection of Alocasia zebrina, not patented. The new Alocasia plant was discovered and selected by the Inventor in November, 2015 as a single plant within a population of plants of the mutation parent selection in a controlled greenhouse environment in Aarlanderveen, The Netherlands.

Asexual reproduction of the new Alocasia plant by vegetative cuttings in a controlled greenhouse environment in Aarlanderveen, The Netherlands since June, 2016 has shown that the unique features of this new Alocasia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Alocasia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘AARALZE001’. These characteristics in combination distinguish ‘AARALZE001’ as a new and distinct Alocasia plant:

- 1. Compact, upright to outwardly arching and uniform plant habit.
- 2. Moderately vigorous growth habit.
- 3. Moderately rapid growth rate.
- 4. Dark green-colored leaves.
- 5. Greyed green-colored petioles that are transversely marked with dark greyed green to black-colored marbling.

Plants of the new Alocasia differ primarily from plants of the mutation parent selection in plant habit as plants of the new Alocasia are much more compact than plants of the mutation parent selection.

Plants of the new Alocasia can be compared to plants of Alocasia zebrina ‘Reticulata’, not patented. In side-by-side comparisons plants of the new Alocasia differ primarily from plants of ‘Reticulata’ in the following characteristics:

- 1. Leaves of plants of the new Alocasia are shorter and broader than leaves of plants of ‘Reticulata’.
- 2. Leaves of plants of the new Alocasia are solid green in color whereas leaves of plants of ‘Reticulata’ are variegated.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Alocasia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alocasia plant.

The photograph on the first sheet is a side perspective view of a typical plant of ‘AARALZE001’ grown in a container.

The photograph on the second sheet is a close-up view of typical leaf petioles of ‘AARALZE001’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 14-cm containers in Aarlanderveen, The Netherlands during the winter in a glass-covered greenhouse. Plants were grown under environmental conditions and cultural practices which approximate those generally used in commercial Alocasia production. During the production of the plants, day temperatures ranged from 20° C. to 28° C. and night temperatures ranged from 18° C. to 22° C. Plants were six months from planting when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
