plant named ‘OVROCKS08’

Abstract

A new and distinct x Gasteraloe plant named ‘OVROCKS08’ which is characterized by dark green foliage that is moderately to densely covered with very light greyed-green protuberances randomly arranged on the leaf surface, protuberances along the distal centerline of the abaxial foliar surface that are arranged in a distinct line and modified into spines like those of the foliar margins, 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 xGasteraloe beguinii.

Variety denomination: The inventive variety of xGasteraloe disclosed herein has been given the variety denomination ‘OVROCKS08’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2020/2874, filed on Nov. 13, 2020, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘OVROCKS08’ originated as a naturally occurring, whole-plant mutation of an unnamed xGasteraloe beguinii plant (not patented). The inventor of ‘OVROCKS08’ is a commercial ornamental plant producer and regularly discovers mutations of xGasteraloe at his greenhouse operation in Bleiswijk, The Netherlands. For said mutations which seem to exhibit commercial potential, cuttings are taken to produce trial plants which are subsequently grown for evaluation.

The variety now called ‘OVROCKS08’ was initially discovered in the summer of 2016 as a whole-plant mutation of an unnamed xGasteraloe plant which exhibited dark green foliage, lighter green near the base, with uniquely arranged foliar protuberances and dentate foliar margins. At the time of discovery, cuttings were taken and the resulting plants were evaluated at the inventor's greenhouse. After further evaluation it was determined that the candidate plant's unique foliage characteristics would prove favorable for commercial marketability. The new plant was given the denomination ‘OVROCKS08’.

Asexual Reproduction: The variety now called ‘OVROCKS08’ was first asexually propagated by stem cuttings in the summer of 2016 at a greenhouse in Bleiswijk, The Netherlands and has since been vegetatively propagated through four additional generations. Through subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘OVROCKS08’ 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 ‘OVROCKS08’. These characteristics in combination distinguish ‘OVROCKS08’ as a new and distinct xGasteraloe cultivar:

• • 1. ‘OVROCKS08’ exhibits lanceolate foliage, with a long mucronate tip, growing in a compact basal rosette with secondary rosettes eventually developing at the base of the primary rosette; and
  • 2. ‘OVROCKS08’ exhibits relatively dark green foliage that is moderately to densely covered with very light greyed-green protuberances that are randomly arranged on the leaf surface; and
  • 3. ‘OVROCKS08’ exhibits a subset of protuberances along the distal centerline of the abaxial foliar surface, arranged in a distinct line, that are modified into spines; and
  • 4. ‘OVROCKS08’ exhibits finely dentate margins with very light greyed-green teeth.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in November of 2020 describe averages from a sample set of six specimens of 1 year old ‘OVROCKS08’ 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. ‘OVROCKS08’ 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).

A botanical description of ‘OVROCKS08’ and a comparison with the parent and closest known comparator is provided below.
