plant named ‘OVROCKS11’

- Ovata B.V.

A new and distinct xGasteraloe plant named ‘OVROCKS11’ which is characterized by dark green carinate foliage that is moderately to densely covered with very light greyed-green protuberances, adaxial foliar protuberances are arranged in highly irregular transverse lines, abaxial foliar protuberances are arranged in distinct transverse lines, protuberances along the distal centerline of the abaxial foliar surface that are modified into spines and arranged in a distinct longitudinal line, and finely dentate margins with very light greyed-green teeth. 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 Aloe aristata x Gasteria carinata, which is synonymous with the nothogenus and species, xGasteraloe beguinii.

Variety denomination: The inventive variety of xGasteraloe disclosed herein has been given the variety denomination ‘OVROCKS11’.

BACKGROUND OF THE INVENTION

Parentage: ‘OVROCKS11’ is a seedling selection resulting from the controlled pollination of an unnamed Aloe variegata plant (unpatented), the seed parent, with an unnamed Gasteria carinata plant (unpatented), the pollen parent. The crossing was made by the inventor in August of 2014 at a commercial greenhouse in Bleiswijk, the Netherlands. In early 2015, one seedling from said cross was observed to exhibit unique foliage and growth characteristics when compared to the parent plants and all other progenies. After confirming the stability of the unique characteristics first observed, the new plant was selected for commercialization and given the name, ‘OVROCKS11’.

Asexual Reproduction: The variety now called ‘OVROCKS11’ was first asexually propagated by stem cuttings in March of 2015 at a greenhouse in Bleiswijk, The Netherlands and has since been vegetatively propagated through several additional generations. Through these subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘OVROCKS11’ 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 ‘OVROCKS11’. These characteristics in combination distinguish ‘OVROCKS11’ as a new and distinct xGasteraloe cultivar:

    • 1. ‘OVROCKS11’ exhibits long, lanceolate foliage that is moderately concaved and carinate; and
    • 2. ‘OVROCKS11’ exhibits relatively dark green foliage that is moderately to densely covered with very light greyed-green protuberances; and
    • 3. ‘OVROCKS11’ exhibits adaxial foliar protuberances are arranged in highly irregular transverse lines across the laminar surface; and
    • 4. ‘OVROCKS11’ exhibits abaxial foliar protuberances are arranged in distinct transverse lines across the laminar surface, with a small subset of protuberances along the distal centerline modified into spines and arranged in a distinct longitudinal line; and
    • 5. ‘OVROCKS11’ exhibits finely dentate margins with very light greyed-green teeth, generally appearing as nearly white.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in February of 2023 describe averages from a sample set of six specimens of 2 years-old ‘OVROCKS11’ plants grown in 12 cm nursery containers at commercial greenhouse in Bleiswijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for xGasteraloe 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. ‘OVROCKS11’ 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).
