plant named ‘OVPEARLS13’

- Ovata B.V.

A new and distinct variety of Echeveria plant named ‘OVPEARLS13’ which is characterized by a small basal rosette of loosely held, broadly obovate foliage with a relaxed attitude, lightly to moderately glaucous juvenile foliage that is somewhat glossy, moderately glaucous mature foliage with a matte luster, and foliage that is covered with a layer of greyed-green epicuticular wax which gives the foliage a greyed-green appearance. 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 Echeveria gibbiflora.

Variety denomination: The inventive variety of Echeveria disclosed herein has been given the variety denomination ‘OVPEARLS13’.

BACKGROUND OF THE INVENTION

Parentage: ‘OVPEARLS13’ originated as a naturally occurring, whole-plant mutation Echeveria gibbiflora ‘Green Pearl’ (Community Plant Variety Rights grant number 30762). The inventor of ‘OVPEARLS13’ is a commercial ornamental plant producer and regularly discovers mutations of Echeveria sp. 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 ‘OVPEARLS13’ was initially discovered in early 2018 as a whole-plant mutation of Echeveria gibbiflora ‘Green Pearl’ which exhibited somewhat glossy juvenile foliage, slightly darker green foliage which remained green year-round and was devoid of the pink coloration along the 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 ‘OVPEARLS13’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVPEARLS13’, by way of rooting leaf cuttings, was first initiated in the autumn of 2017 at the inventor's commercial greenhouse in Bleiswijk, the Netherlands. Through eleven subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘OVPEARLS13’ 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 ‘OVPEARLS13’. These characteristics in combination distinguish ‘OVPEARLS13’ as a new and distinct Echeveria cultivar:

    • 1. ‘OVPEARLS13’ exhibits a small basal rosette of loosely held foliage; and
    • 2. ‘OVPEARLS13’ exhibits broadly obovate foliage with a relaxed attitude; and
    • 3. ‘OVPEARLS13’ exhibits lightly to moderately glaucous juvenile foliage that is somewhat glossy; and
    • 4. ‘OVPEARLS13’ exhibits moderately glaucous mature foliage with a matte luster; and
    • 5. ‘OVPEARLS13’ exhibits yellow-green to green foliage that is covered with a layer of greyed-green epicuticular wax which gives the foliage a greyed-green appearance.

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 ‘OVPEARLS13’.

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 ‘OVPEARLS13’.

FIG. 4 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, a comparison between ‘OVPEARLS13’, left, and its parent, ‘Green Pearl, on the right.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in December of 2021 describe averages from a sample set of six specimens of 8-month-old ‘OVPEARLS13’ plants grown in 12 cm nursery containers at commercial greenhouse in Bleiswijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Echeveria which consisted of minimal subsurface irrigation, fertilizer applications, and chemical pest control measures against thrips as required. No other chemical pest and disease control measures were taken. Plants were grown under approximately 50 percent shade after propagation and later exposed to full sun once they began to mature. 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. ‘OVPEARLS13’ 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).
