plant named ‘Petra's Perle’

A new and distinct Echeveria cultivar named ‘Petra's Perle’ is disclosed, characterized by compact rosettes of foliage colored intense rose or violet-burgundy, depending upon environmental conditions. The new cultivar is robust growing, as compared to other commercially known Echeverias, enabling faster commercial production of the cultivar. The new cultivar ‘Petra's Perle’ can be propagated by leaves, enhancing commercial propagation. The new variety is an Echeveria, part of the Crassulaceae complex that includes Aeonium, Crassula, Graptopetalum, Pachyphytum, Sedum and others. Echeveria is a popular genus, typically produced as container plants for the patio or as landscape plants, as a variety of ornamental purposes.

Description

Latin name of the genus and species: Echeveria hybrida.

Variety denomination: ‘PETRA'S PERLE’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘Petra's Perle’, is the product of a planned breeding program. The new variety originated as a naturally occurring whole plant mutation of the unpatented parent, Echeveria hybrida ‘Perle von Nurnberg’. The new cultivar ‘Petra's Perle’ was discovered by the inventor, Renee O' Connell, in June 2015, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Petra's Perle’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in August, 2015. Echeveria ‘Petra's Perle’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Petra's Perle’ 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 ‘PETRA'S PERLE’. These characteristics in combination distinguish ‘PETRA'S PERLE’ as a new and distinct Echeveria cultivar:

    • 1 The rosettes of Echeveria ‘Petra's Perle’ are comprised of many leaves of nearly a taupe red rose in color, to violet-burgundy depending upon the light conditions.
    • 2. Echeveria ‘Petra's Perle’ grows quickly, enhancing production times, as compared with many other Echeverias.
    • 3. The new cultivar Echeveria ‘Petra's Perle’, a sport of Echeveria ‘Perle von Nurnberg’, displays a rosette color that is much more intense than the color displayed by a typical Echeveria ‘Perle von Nurnberg’.
    • 4. Echeveria ‘Petra's Perle’ can be propagated by leaves, thereby enhancing propagation in the commercial nursery.

PARENTAL COMPARISON

Plants of the new cultivar ‘Petra's Perle’ can be compared to plants of the unpatented, parent Echeveria ‘Perle von Nurnberg’, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Petra's Perle’ display a darker violet-burgundy foliage color, not displayed by Echeveria ‘Perle von Nurnberg’. The new cultivar ‘Petra's Perle’ forms rosettes that are of more upright morphology than the rosettes of parent Echeveria ‘Perle von Nurnberg’.

COMMERCIAL COMPARISON

The new cultivar ‘Petra's Perle’ can be compared to the unpatented commercial variety Echeveria ‘Violet Queen’. Plants of the Echeveria ‘Violet Queen’ are similar to plants of the new cultivar ‘Petra's Perle’ in most horticultural characteristics. However, the new cultivar ‘Petra's Perle’ differs in the following:

    • 1. Echeveria ‘Petra's Perle’ displays rosettes of a saturated rose to saturated rose to violet-burgundy color; as compared with the pallid milky color of Echeveria ‘Violet Queen’.
    • 2. Echeveria ‘Petra's Perle’ forms single rosettes that can grow to 5″ in diameter, whereas Echeveria ‘Violet Queen’ produces smaller rosettes, and only attains a larger size by forming a cluster.
    • 3. Echeveria ‘Petra's Perle’, due to its more saturated color, can be used in many more decorative projects as the rose burgundy provides aesthetic contrast with greens, blues, lilacs and other colors, whereas the pallid coloration of Echeveria ‘Violet Queen’ limits its use to subdued palettes in decorative projects.
    • 4. Echeveria ‘Petra's Perle’ grows faster than Echeveria ‘Violet Queen’, thereby enhancing production times in a commercial nursery environment.
    • 5. Echeveria ‘Petra's Perle’ has less disease pressure during the warmer summer months than does Echeveria ‘Violet Queen’.

The new cultivar ‘Petra's Perle’ can be compared to the unpatented commercial variety Graptoveria ‘Fred Ives’. Plants of the Graptoveria ‘Fred Ives’ are similar to plants of the new cultivar ‘Petra's Perle’ in most horticultural characteristics. However, the new cultivar ‘Petra's Perle’ differs in the following:

    • 1. Echeveria ‘Petra's Perle’ forms rosettes of saturated rose to violet-leaves, as compared with the lilac leaves produced by Graptoveria ‘Fred Ives’.
    • 2. Echeveria ‘Petra's Perle’ exhibits a compact rosette morphology, whereas Graptoveria ‘Fred Ives’ grows with a taller shrub morphology.
    • 3. Echeveria ‘Petra's Perle’, due to its saturated, unusual color and concentric rosettes, can be more readily utilized for decorative uses such as bouquets, entertainment centerpieces and to provide accent colors for other colors, such as greens, blues, whites, and others, than can Graptoveria ‘Fred Ives’ with its monotone lilac branches.
    • 4. Echeveria ‘Petra's Perle’, due to its saturated leaf color, contrasted by light colored hyaline margins, produces a more attractive rosette than does Graptoveria ‘Fred Ives’, with its monotone lilac rosette, and no discernible contrasting margin.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 through FIG. 4 illustrate in full color typical plants of ‘PETRA'S PERLE’ grown in a greenhouse in Vista, Calif. 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 the new Echeveria plant. The following photographs depict plants grown under natural light conditions of 2500-4000 foot-candles. Temperatures ranged from −1° C. to 29° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.
