plant named ‘Pink Diamond’

A new and distinct plant of Echeveria hybrida named ‘Pink Diamond’ is disclosed, characterized by robust growth on plants forming a compact rosette of geometric pink leaves with hyaline margins. Plants produce foliage with more pink coloration in cool temperatures, and also maintain a pink foliar color in warmer temperatures as well. Echeveria is a popular genus, typically produced as container plants for the patio or as landscape plants.

Description

Latin name of the genus and species: Echeveria hybrida.

Variety denomination: ‘PINK DIAMOND’.

BACKGROUND OF THE INVENTION

The new cultivar Echeveria ‘Pink Diamond’, is the product of chance discovery by the inventor. The new variety was discovered as a whole plant, naturally occurring mutation of the parent variety, the unpatented Echeveria hybrida cultivar known as ‘Lola’. The discovery was made during November of 2015, in Vista, Calif., at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Pink Diamond’ was first performed in Vista, Calif., at a commercial greenhouse, by vegetative offsets in March of 2016. Echeveria ‘Pink Diamond’ has since produced at least 10 generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Pink Diamond’ 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 ‘PINK DIAMOND’. These characteristics in combination distinguish ‘PINK DIAMOND’ as a new and distinct Echeveria cultivar:

  • 1. Echeveria ‘Pink Diamond’ forms compact rosettes of geometric pink leaves with hyaline margins, a combination not encountered often in the market of “pink” succulents.
  • 2. Echeveria ‘Pink Diamond’ will become more pink with cool temperatures, but always retains a pink coloration, whereas many other “pink” succulents found in today's market only blush pink in cool temperatures and are usually silvery blue or white at other times.
  • 3. Echeveria ‘Pink Diamond’, an attractive, compact pink rosette, is ideal for use as an accent in groups of blue or green Echeverias, or as an eye-catching accent in a decorative grouping of succulents, particularly those of orange or yellow tones.
  • 4. Echeveria ‘Pink Diamond’ is a robust grower, not displaying the problematic tendencies encountered with many of the other “pink” Echeverias with genetic lines of Echeveria lauii and Echeveria agavoides ‘Romeo’ (unpatented).

PARENTAL COMPARISON

Plants of the new cultivar ‘Pink Diamond’ are similar to plants of the parent in most horticultural characteristics. However, plants of the new cultivar ‘Pink Diamond’ differ in the following:

  • 1. Echeveria ‘Pink Diamond’ forms pink rosettes, with a slight upswept tendency to the leaves, whereas Echeveria ‘Lola’ forms alabaster rosettes, blushed in violet during cooler temperatures.
  • 2. Echeveria ‘Pink Diamond’ is relatively pathogen free, as is Echeveria ‘Lola’.
  • 3. Although Echeveria ‘Lola’ has the same hyaline margins as Echeveria ‘Pink Diamond, Echeveria ‘Pink Diamond’ exhibits a greater contrast between the rosette color and the hyaline margin than does Echeveria ‘Lola’.

COMMERCIAL COMPARISON

The new cultivar ‘Pink Diamond’ can be compared to the commercial variety Echeveria ‘Cubic Frost’, U.S. Plant Pat. No. 27,527. Plants of the new cultivar ‘Pink Diamond’ differ in the following:

  • 1. Echeveria ‘Pink Diamond’ forms compact pink rosettes of geometric leaves, whereas Echeveria ‘Cubic Frost’ has upswept, longer pink tubular leaves arranged in a rosette.
  • 2. Echeveria ‘Pink Diamond’ exhibits hyaline margins whereas Echeveria ‘Cubic Frost’ does not have hyaline margins.
  • 3. Echeveria ‘Pink Diamond’ produces leaves that are pink in color, whereas Echeveria ‘Cubic Frost’ produces leaves that are of a more frosted pink due to the glaucous covering.

The new cultivar ‘Pink Diamond’ can be compared to the unpatented Echeveria shaviana ‘Pink Frills’. Plants of the new cultivar ‘Pink Diamond’ are similar to Echeveria ‘Pink Frills’ in most horticultural characteristics. However, plants of the new cultivar ‘Pink Diamond’ differ in the following:

  • 1. Echeveria ‘Pink Diamond’ forms upswept rosettes of pink leaves, whereas Echeveria shaviana ‘Pink Frills’ forms rosettes of lateral leaves of powdery lilac with pink margins.
  • 2. Echeveria ‘Pink Diamond’ exhibits concentric, roughly spatulate leaves whereas, Echeveria shaviana ‘Pink Frills’ displays longer leaves with finely crenulate margins towards the apex of the leaf.
  • 3. Echeveria ‘Pink Diamond’ exhibits pink leaves with highly contrasting hyaline margins, whereas Echeveria shaviana ‘Pink Frills’ does not display a hyaline leaf margin.
  • 4. Echeveria ‘Pink Diamond’ is a more robust grower than is Echeveria shaviana ‘Pink Frills’, particularly as Echeveria ‘Pink Diamond’ does not display the seasonal dormancy that seems to cause Echeveria shaviana ‘Pink Frills’ to be prone to lethal fungal diseases.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of new Echeveria ‘Pink Diamond’. Plants photographed are approximately 4 months from a rooted cutting.

FIG. 1 illustrates in full color the plant being described of Echeveria ‘Pink Diamond’, grown in a greenhouse (approximately 2000-2500 foot candles) in Vista, Calif.

FIG. 2 illustrates in full color a plant of Echeveria ‘Pink Diamond’, on the left in the figure, and a plant of the comparator ‘Lola’, on the right in the figure. Both plants were grown in a greenhouse (approximately 2500 foot candles) in Vista, Calif. under identical conditions.
