plant named ‘Autumn Flame’

A new and distinct Echeveria cultivar named ‘Autumn Flame’ is disclosed, characterized by overlapping foliage forming rosettes. Foliage is uniquely shiny and mahogany in color. Plants grow unusually rapidly and exhibit tolerance for both heat and humidity. 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: ‘AUTUMN FLAME’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘Autumn Flame’, is the product of a planned breeding program. The new variety originated from a cross pollination of the unpatented seed parent, Echeveria ‘Doble Cabeza’ with the pollen parent an unpatented, proprietary variety of Echeveria referred to as ‘Color 07’. The cross pollination was made during April 2012 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘Autumn Flame’ was discovered by the inventor, Renee O' Connell in September 2013, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Autumn Flame’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in September 2013. Echeveria ‘Autumn Flame’ 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 ‘Autumn Flame’ 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 ‘AUTUMN FLAME’. These characteristics in combination distinguish ‘AUTUMN FLAME’ as a new and distinct Echeveria cultivar:

    • 1. Rich, mahogany color not seen in commonly in Echeveria.
    • 2. Shiny, undulate foliage.
    • 3. Unusual rosetting habit. Leaves arise from the plant center in an “overlapping” morphology; each leaf slightly overlaps the proximal leaf. Due to this overlapping of the leaves, as the plant grows and leaves appear one above another, the overall appearance is of a “spiralling” or “twirling” rosette.
    • 4. Relatively rapid growth for an Echeveria, reducing production time.
    • 5. Exhibited tolerance for combined heat and humidity.
    • 6. Coloration suitable and complimentary for combination plantings.

PARENTAL COMPARISON

Plants of the new cultivar ‘Autumn Flame’ are similar in most horticultural characteristics to the seed parent variety. However, plants of the new cultivar ‘Autumn Flame’ differ in the following:

    • 1. ‘Autumn Flame’ does not suffer the same vulnerability to Fusarium echeveriae exhibited by Echeveria ‘Doble Cabeza’.
    • 2. ‘Autumn Flame’ produces larger rosettes than Echeveria ‘Dobie Cabeza’, and without the tendency to bifurcate that Echeveria ‘Doble Cabeza’ exhibits.
    • 3. ‘Autumn Flame’ exhibits leaves of mahogany with a satin texture, that do not exhibit the tendency towards physiological “edema” during certain times of the year, whereas the leaves of Echeveria ‘Doble Cabeza’ are thicker, less undulate, do not exhibit the “satin” texture, and can exhbit some tendency towards physiological “edema” during certain times of the year.
    • 4. The leaf margins of ‘Autumn Flame’ are of lighter red than the overall mahogany leaf color, whereas the leaf margins of Echeveria ‘Doble Cabeza’ are the same color as the leaves.

Plants of the new cultivar ‘Autumn Flame’ can be compared to plants of the pollen parent, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Autumn Flame’ differ in the following:

    • 1. ‘Autumn Flame’ has more undulate leaf margins than does Echeveria ‘Color 07’.
    • 2. Echeveria ‘Color 07’ exhibits matte textured, blue violet leaves, whereas Echeveria ‘Autumn Flame’ exhibits satin textured, mahogany colored leaves.
    • 3. The rosette of ‘Autumn Flame’ tends to grow taller with time, whereas the rosette of Echeveria ‘Color 07’ tends to maintain the flatter morphology.
    • 4. Echeveria ‘Color 07’ produces leaves that are more rounded apically, whereas the leaves of ‘Autumn Flame’ are longer, and mucronate at the apex of the leaf.

COMMERCIAL COMPARISON

The new cultivar ‘Autumn Flame’ can be compared to the unpatented commercial variety Echeveria ‘Perle van Nurnburg’. Plants of the new cultivar ‘Autumn Flame’ differ in the following:

    • 1. Echeveria ‘Autumn Flame’ exhibits rosettes of mahogany, whereas those of Echeveria ‘Perle von Nurnberg’ are a lilac-mauve color.
    • 2. The leaves of Echeveria ‘Autumn Flame’ have a shiny texture, whereas the leaves of Echeveria ‘Perle von Nurnberg’ have a matte, glaucous texture.

The new cultivar ‘Autumn Flame’ can be compared to the unpatented commercial variety Echeveria ‘Afterglow’. Plants of the new cultivar ‘Autumn Flame’ are similar to ‘Afterglow’ in most horticultural characteristics. However, plants of the new cultivar ‘Autumn Flame’ differ in the following:

    • 1. ‘Autumn Flame’ produces leaves with a shiny, texture, whereas Echeveria ‘Afterglow’ produces matte, glaucous leaves.
    • 2. ‘Autumn Flame’ has a warm mahogany colored rosette as compared to the blue and purple rosette of Echeveria ‘Afterglow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 through FIG. 2 illustrate in full color typical plants of ‘AUTUMN FLAME’ grown in a greenhouse in Vista, Calif. Plants are both approximately 5 months from a rooted cutting. 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 to over 4000 foot-candles. Temperatures ranged from 10° C. to 38° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.
