plant named ‘OVPEARLS11’

- Ovata B.V.

A new and distinct variety of Echeveria plant named ‘OVPEARLS11’ which is characterized by succulent foliage that is somewhat loosely held in a basal rosette, glaucous foliage with a pale blue-grey general appearance, juvenile foliage with greyed-red tips, and mature foliage with apical margins and laminar tips which generally appear as a soft pink coloration. 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 elegans x pulidonis.

Variety denomination: The inventive variety of Echeveria disclosed herein has been given the variety denomination ‘OVPEARLS11’.

BACKGROUND OF THE INVENTION

Parentage: ‘OVPEARLS11’ is a seedling selection, presumed to be the result of the open pollination of an unnamed Echeveria elegans plant (unpatented), the seed parent, and a plurality of unnamed Echeveria pulidonis plants (not patented), the presumed pollen parent. The exact pollen parent is unknown. The crossing is believed to have occurred in the summer of 2016 at a commercial greenhouse in Bleiswijk, the Netherlands. In early 2017, one seedling from said cross was observed to exhibit unique foliage and growth characteristics 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, ‘OVPEARLS11’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVPEARLS11’, 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 ‘OVPEARLS11’ 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 ‘OVPEARLS11’. These characteristics in combination distinguish ‘OVPEARLS11’ as a new and distinct Echeveria cultivar:

    • 1. ‘OVPEARLS11’ exhibits a flattened globular to globular profile with succulent foliage that is somewhat loosely held in a basal rosette; and
    • 2. ‘OVPEARLS11’ exhibits concaved oblanceolate foliage with an apiculate apex which is curled upward; and
    • 3. ‘OVPEARLS11’ exhibits glaucous foliage that is covered with a layer of greyed-green epicuticular wax which gives the foliage a pale blue-grey appearance; and
    • 4. ‘OVPEARLS11’ exhibits juvenile foliar margins that are lightly suffused with greyed-red along the apical margins and laminar tip; and
    • 5. ‘OVPEARLS11’ exhibits mature foliage with light purple apical margins and greyed-purple laminar tips which generally appears as a soft pink coloration.

BRIEF DESCRIPTION OF THE FIGURES

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 ‘OVPEARLS11’.

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 ‘OVPEARLS11’.

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 ‘OVPEARLS11’.

 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 1 year old ‘OVPEARLS11’ plants grown in 8.5 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. ‘OVPEARLS11’ 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).
