Aloe plant named ‘AMIAL2202’

Abstract

A new and distinct Aloe plant named ‘AMIAL2202’ which is characterized by a rosette of succulent foliage that gives rise to an abundance of small, secondary rosettes which will eventually ring the entire primary rosette, foliage with an upright attitude, dark green foliage with a moderate abundance of light greyed-green, appearing nearly white, oblong protuberances loosely arranged in highly irregular transverse rows on the lower leaf surface, serrate leaf margins with an abundance of spine-like teeth, and the stability of these characteristics from generation to generation.

Description

[0001] Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Aloe hybrid.

[0002] Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘AMIAL2202’.BACKGROUND OF THE INVENTION

[0003] Parentage: ‘AMIAL2202’ is a seedling selection resulting from the controlled cross-pollination of an Aloe arborescens x humilis hybrid plant named ‘AMIAL2135’ (Community Plant Variety Rights No. 2021 / 1788) and an unnamed Aloe vera plant that typifies the species (not patented). The crossing was made by the inventor in the spring of 2020 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the spring of 2021, one seedling was observed which exhibited an abundance of erect, dark green foliage with an abundance of oblong near-white protuberances and prominent dentate margins, unlike the parent plants and all other progeny in the trials. Upon confirmation of distinctness and stability, ‘AMIAL2202’ was selected for commercialization.

[0004] Asexual Reproduction: Asexual reproduction of the new cultivar ‘AMIAL2202’, by way of rooting leaf cuttings, was first initiated in the spring of 2022 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.SUMMARY OF THE INVENTION

[0005] The cultivar ‘AMIAL2202’ 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 ‘AMIAL2202’. These characteristics in combination distinguish ‘AMIAL2202’ as a new and distinct Aloe hybrid plant:

[0006] 1. ‘AMIAL2202’ exhibits a primary rosette of succulent foliage which gives rise to an abundance of small, secondary rosettes which will eventually ring the entire primary rosette with age; and

[0007] 2. ‘AMIAL2202’ exhibits dark green succulent foliage which is held upright and slightly outward; and

[0008] 3. ‘AMIAL2202’ exhibits dentate leaf margins with an abundance of large, spine-like teeth that are colored light greyed-green; and

[0009] 4. ‘AMIAL2202’ exhibits a moderate abundance of light greyed-green, appearing nearly white, oblong protuberances loosely arranged in highly irregular transverse rows on the lower leaf surface.BRIEF DESCRIPTION OF THE FIGURES

[0010] FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘AMIAL2202’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. This plant is approximately 30 weeks old, shown planted in a 12 cm container.

[0011] FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, adaxial surface of the mature foliage ‘AMIAL2202’.

[0012] FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the abaxial surface of the mature foliage of ‘AMIAL2202’.BOTANICAL DESCRIPTION OF THE PLANT

[0013] The following observations and measurements made in October of 2022 describe averages from a sample set of six specimens of 30-week-old ‘AMIAL2202’ plants grown in 12 cm nursery containers at commercial greenhouse in Honselersdijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe which consisted of minimal overhead irrigation, minimal fertilizer applications, and control measures for common pests and diseases. Plants were produced under 50 percent shade and no photoperiodic treatments or artificial light was provided to the plants.

[0014] Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘AMIAL2202’ 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, Sixth Edition.
