Description

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

Variety denomination: The inventive variety of Aloe disclosed herein has been given the variety denomination ‘OVROCKS03’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/2563, filed on Oct. 12, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘OVROCKS03’ is a seedling selection resulting from the controlled pollination of an unnamed Aloe haworthioides plant (unpatented), the seed parent, with an unnamed Aloe descoingsii plant (unpatented), the pollen parent. The crossing was made by the inventor in January of 2009 at a greenhouse in Fallbrook, Calif. In March of 2010, one seedling was observed which exhibited an abundance of protuberances presenting as raised ribs and soft spines when compared to the parent plants and all other progeny. After confirming the stability of the unique characteristics first observed, the new plant was selected for commercialization and given the name, ‘OVROCKS03’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVROCKS03’, by way of rooting leaf cuttings, was first initiated in March of 2010 at a 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

The cultivar ‘OVROCKS03’ 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 ‘OVROCKS03’. These characteristics in combination distinguish ‘OVROCKS03’ as a new and distinct Aloe cultivar:

    • 1. ‘OVROCKS03’ exhibits a globular plant form with foliage arranged in a compact basal rosette; and
    • 2. ‘OVROCKS03’ exhibits deltoid to narrowly deltoid succulent foliage which is held upright; and
    • 3. ‘OVROCKS03’ exhibits foliage which densely covered with prominent raised protuberances appearing as ribs and soft spines.

BRIEF DESCRIPTION OF THE FIGURES

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 ‘OVROCKS03’ grown in a commercial greenhouse in Bleiswijk, the Netherlands. This plant is approximately 12 months old, shown planted in an 8.5 cm container.

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 ‘OVROCKS03’.

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 ‘OVROCKS03’.

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 ‘OVROCKS03’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in June of 2017 describe averages from a sample set of six specimens of 12 months old ‘OVROCKS03’ plants grown in 8.5 cm nursery containers at a commercial greenhouse in Bleiswijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Aloe which consisted of minimal overhead irrigation and fertilizer applications. No pest or disease control measures were utilized in production. Plants were grown under shade (approximately 10,000 lux) 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. ‘OVROCKS03’ 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).
