plant named ‘OVGRPP’

Abstract

A new and distinct Echeveria cultivar named ‘OVGRPP’ which is characterized by a flattened globular plant form with greyed-purple foliage, narrowly margined pink and becoming red-purple with maturity, arranged in a basal rosette borne on a short stem. The foliage is moderately pruinose which creates a distinct bluish hue. 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 hybrid.

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

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2016/2371, filed Sep. 29, 2016, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘OVGRPP’ is a spontaneous, naturally occurring whole-plant mutation of Echeveria ‘Perle Von Nürnberg’ (not patented) which was discovered by the inventor in April of 2009 at a commercial greenhouse in Bleiswijk, The Netherlands. The mutation was noted for its thick, robust pink to red foliage by comparison to the thinner, weaker greyed-purple foliage of the parent plant.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OVGRPP’, by way of rooting leaf cuttings, was first initiated in September of 2009 at the inventor's commercial greenhouse in Bleiswijk, The Netherlands. Through ten subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

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

• • 1. ‘OVGRPP’ exhibits a flattened globular plant form with foliage arranged in a basal rosette which eventually forms a short, unbranched stem with age; and
  • 2. ‘OVGRPP’ exhibits broad spatulate foliage and an apiculate apex with a slight upwardly curved attitude; and
  • 3. ‘OVGRPP’ exhibits moderately pruinose foliage, which gives the foliage a bluish hue; and
  • 4. ‘OVGRPP’ exhibits juvenile foliage with a greyed-purple general coloration, suffused with red towards the base, and pink margins, the colors becoming more intense with exposure to ultraviolet light; and
  • 5. ‘OVGRPP’ exhibits mature foliage with a greyed-purple general coloration and red-purple margins, the colors becoming more intense with exposure to cooler temperatures.

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 ‘OVGRPP’.

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 ‘OVGRPP’.

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 ‘OVGRPP’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in November of 2016 describe averages from a sample set of six specimens of 5 months old ‘OVGRPP’ plants grown in 11 cm nursery containers at commercial greenhouse in Bleiswijk, The Netherlands. Plants were produced using conventional greenhouse production protocols for Echeveria which consisted of minimal irrigation, by way of ebb and flow benches, and fertilizer applications. No chemical pest and disease control were utilized. 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. ‘OVGRPP’ 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).
