plant named ‘Galaxy Blue’

Abstract

A new and distinct Echeveria cultivar named ‘Galaxy Blue’ is disclosed, characterized by concentric rosettes comprised of an abundance of undulate, icy blue leaves tipped with crimson. Further, the new cultivar ‘Galaxy Blue’ freely offsets, enabling increased and faster propagation in the commercial nursery. The new cultivar ‘Galaxy Blue’ exhibits moderately fast, robust growth, which, in combination with freely offsetting results in attractive clusters at an early age, thereby enhancing production intervals. 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 hybrid.

Variety denomination: ‘GALAXY BLUE’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘Galaxy Blue’, is a product of a planned breeding program. The new variety originated from a cross pollination of the unpatented proprietary seed parent, Echeveria ‘MI-9’ with the pollen parent, the unpatented, proprietary Echeveria hybrid referred to as ‘GLAV07’. The cross pollination was made during May 2011 in Vista, Calif., at a commercial greenhouse. Echeveria ‘Galaxy Blue’, was discovered by the inventor, Renee O Connell, in February, 2012, in Vista, Calif., at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Galaxy Blue’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in April, 2012. Echeveria ‘Galaxy Blue’ 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 ‘Galaxy Blue’ 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 ‘GALAXY BLUE’. These characteristics in combination distinguish ‘GALAXY BLUE’ as a new and distinct Echeveria cultivar:

• • 1. Echeveria ‘Galaxy Blue’ exhibits very concentric, flattened rosettes with an abundance of undulate, icy blue leaves, tipped in crimson.
  • 2. Additionally, Echeveria ‘Galaxy Blue’ exhibits moderately fast growth, in combination with early, profuse offsetting, producing morphologically attractive icy blue clusters.
  • 3. Echeveria ‘Galaxy Blue’ is easily and rapidly propagated due to robust growth, and prolific offsetting, enhancing production times in the commercial nursery.

PARENTAL COMPARISON

Plants of the new cultivar ‘Galaxy Blue’ can be compared to plants of the seed parent Echeveria ‘MI-9’, and are similar in most horticultural characteristics. However, the new cultivar ‘Galaxy Blue’ forms a larger rosette than does the seed parent Echeveria ‘MI-9’, and the new cultivar ‘Galaxy Blue’ produces more offsets than does the seed parent Echeveria ‘MI-9’. The new cultivar ‘Galaxy Blue’ grows much faster and much more robustly than does Echeveria ‘MI-9’, thereby reducing production times measurably, as compared to Echeveria ‘MI-9’. Echeveria ‘Galaxy Blue’ differs from the seed parent ‘MI-9’ in that it forms low-growing rosettes of icy blue, undulate leaves, whereas the seed parent ‘MI-9’ produces taller rosettes that are comprised of rounded, chunky blue leaves. Additionally, the new cultivar ‘Galaxy Blue’ produces more inflorescences and more complex inflorescences that the simple inflorescences produced by the seed parent ‘MI-9’.

Plants of the new cultivar ‘Galaxy Blue’ can be compared to plants of the pollen parent Echeveria ‘GLAV07’, and are similar in most horticultural characteristics. However, the new cultivar ‘Galaxy Blue’ forms much more concentric, geometric rosettes than the lax, non-concentric rosettes formed by Echeveria ‘GLAV07’. Additionally, the new cultivar ‘Galaxy Blue’ is icy blue in color, whereas the pollen parent Echeveria ‘GLAV07’ is a pallid lavender. The new cultivar ‘Galaxy Blue’ is freely offsetting, as compared to the sparse offsetting of the pollen parent Echeveria ‘GLAV07’.

COMMERCIAL COMPARISON

The new cultivar ‘Galaxy Blue’ can be compared to the, unnamed Echeveria peacockii. Plants of Echeveria peacockii are similar to plants of the new cultivar ‘Galaxy Blue’ in most horticultural characteristics. However, the new cultivar ‘Galaxy Blue’ displays a more concentric, low growing morphology than does Echeveria peacockii. In addition, the new cultivar ‘Galaxy Blue’ forms a more concentric rosette than does Echeveria peacockii, producing a more aesthetic rosette. In addition, the new cultivar ‘Galaxy Blue’ produces rosettes with an abundance of leaves, creating a fuller appearance, as compared with Echeveria peacockii. Plants of the cultivar ‘Galaxy Blue’ offset more profusely than Echeveria peacockii, enhancing the propagation rate, and producing a morphologically aesthetic cluster.

The new cultivar ‘Galaxy Blue’ can be compared to the unpatented commercial variety Echeveria ‘Perle von Nurnberg’. Plants of Echeveria ‘Perle von Nurnberg’ are similar to plants of the new cultivar ‘Galaxy Blue’ in most horticultural characteristics. However, the cultivar ‘Galaxy Blue’ displays a more concentric rosette than is displayed by Echeveria ‘Perle von Nurnberg’. In addition, the new cultivar ‘Galaxy Blue’ produces rosettes with an abundance of leaves, creating a much more full appearance, whereas Echeveria ‘Perle von Nurnberg’ has less leaves per rosette. The new cultivar ‘Galaxy Blue’ offsets profusely, enhancing propagation times, and producing a more aesthetic plant, whereas Echeveria ‘Perle von Nurnberg’ rarely offsets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 through FIG. 3 illustrate in full color typical plants of ‘GALAXY BLUE’ grown in a greenhouse in Vista, Calif. Age of the plants is approximately 1 year. 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.
