Aloe plant named ‘OVROCKS14’

Abstract

A new and distinct Aloe aristata cultivar named ‘OVROCKS14’ which is characterized by compact erect foliage arranged in a basal rosette that relaxes as the plant matures, foliage that is a gradient of yellow-green, green, to greyed green which is densely covered with large greyed-green protuberances and prominent spines along the margins, mucronate laminar tips that develop from white to greyed-orange with maturation, 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 aristata.

[0002] Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘OVROCKS14’.BACKGROUND OF THE INVENTION

[0003] Parentage: ‘OVROCKS14’ is a seedling selection resulting from the controlled pollination of the seed parent, Aloe aristata ‘28’ (not patented), and Aloe aristata ‘35’ (not patented), the pollen parent. In 2015, the inventor initiated the crossing at a commercial greenhouse in Bleiswijk, the Netherlands. Both parents were developed by the inventor and never released to the public. The resulting seedlings were grown to maturity to evaluate for desirable characteristics. In 2017, one of the plants was observed to exhibit compact foliage that becomes outreaching as the plant matures, white mucronate laminar tips which mature into a greyed-orange color and prominent greyed-green protuberances relative to the parents and other progeny. The plant was isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘OVROCKS16’ was selected for commercialization in 2017.

[0004] Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVROCKS14’, by way of rooting leaf cuttings, was first initiated in the summer of 2017 at the inventor's commercial greenhouse in Bleiswijk, the Netherlands. The claimed plant has since been asexually propagated by way of meristematic tissue culture propagation. Through eight subsequent generations, the unique features of this cultivar have proven to be stable and true to type.SUMMARY OF THE INVENTION

[0005] The cultivar ‘OVROCKS14’ 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 ‘OVROCKS14’. These characteristics in combination distinguish ‘OVROCKS14’ as a new and distinct Aloe aristata cultivar:

[0006] 1. ‘OVROCKS14’ exhibits compact erect foliage arranged in a basal rosette that relaxes as the plant matures; and

[0007] 2. ‘OVROCKS14’ exhibits foliage colored in a gradient of yellow-green, green to greyed-green, which is densely covered with large, prominent protuberances on both the adaxial and abaxial surfaces, and large prominent spines along the margins; and

[0008] 3. ‘OVROCKS14’ exhibits white mucronate laminar tips which change in coloration to greyed-orange as the plant matures.BRIEF DESCRIPTION OF THE FIGURES

This plant is approximately 36 months old, shown planted in a 12 cm container.

[0010] FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage arrangement of ‘OVROCKS14’.

[0011] FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the adaxial surface of the mature foliage ‘OVROCKS14’.

[0012] FIG. 4 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 ‘OVROCKS14’.BOTANICAL DESCRIPTION OF THE PLANT

[0013] The following observations and measurements made in October of 2016 describe averages from a sample set of six specimens of 36-month-old ‘OVROCKS14’ plants grown in 12 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe which consisted of minimal irrigation and fertilizer applications, and chemical pest and disease control measures against mealy bug and Botrytis as required. Plants were grown under approximately 50 percent shade and no photoperiodic treatments or artificial light was given to the plants.

[0014] Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘OVROCKS14’ 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.
