plant named ‘OVPEARLS06’

Abstract

A new and distinct variety of Echeveria plant named ‘OVPEARLS06’ which is characterized by a flattened globular prolife with an abundance of foliage held in a basal rosette, dark greyed-green and heavily glaucescent foliage which has a gray appearance, and light pink leaf margins which become white at the apex. 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 lilacina.

Variety denomination: The inventive variety of Echeveria disclosed herein has been given the variety denomination ‘OVPEARLS06’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2019/3113, filed on Nov. 27, 2019, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘OVPEARLS06’ is a naturally-occurring, whole-plant mutation of an unnamed Echeveria lilacina plant (not patented) which was discovered by the inventor in March of 2009 at a commercial greenhouse in Bleiswijk, the Netherlands. The mutation was noted for its gray foliage with light pink margins.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVPEARLS06’, by way of rooting leaf cuttings, was first initiated in March of 2009 at the inventor's commercial greenhouse in Bleiswijk, the Netherlands. 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 ‘OVPEARLS06’ 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 ‘OVPEARLS06’. These characteristics in combination distinguish ‘OVPEARLS06’ as a new and distinct Echeveria cultivar:

• • 1. ‘OVPEARLS06’ exhibits a flattened globular plant form with foliage arranged in a basal rosette; and
  • 2. ‘OVPEARLS06’ exhibits spatulate to obovate foliage with an apiculate apex which is held upright near the center of the rosette and becomes progressively more relaxed towards the outer whorls of foliage; and
  • 3. ‘OVPEARLS06’ exhibits dark greyed-green, strongly glaucescent foliage with a grey general coloration; and
  • 4. ‘OVPEARLS06’ exhibits foliage with light pink margins which become white at the apex.

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 ‘OVPEARLS06’ grown in a commercial greenhouse in Bleiswijk, the Netherlands. This plant is approximately 1 year old, shown planted in a 12 cm container.

FIG. 2 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 ‘OVPEARLS06’.

FIG. 3 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 ‘OVPEARLS06’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in November of 2019 describe averages from a sample set of six specimens of 1 year old ‘OVPEARLS06’ 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. ‘OVPEARLS06’ 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).
