plant named ‘SOLAR FLARE’

A new and distinct cultivar of Tacisedum plant named ‘Solar Flare’ is disclosed, characterized by attractive compact plant form with a distinctive star-shaped rosette morphology. Foliage has a distinctive copper-pink marginal color. The new cultivar produces offsets freely while maintaining a compact plant habit. Pink flowers are produced April through June in Southern California. Tacisedum is a useful 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: Tacisedum hybrida.

Variety denomination: ‘SOLAR FLARE’.

BACKGROUND OF THE INVENTION

The new cultivar, Tacisedum ‘SOLAR FLARE’, is the product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented, seed parent, Sedum hybrida ‘S06’ with the pollen parent an unpatented, proprietary variety of Tacitus bellum referred to as ‘Ruby 03’. The cross pollination was made during February 2014 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘SOLAR FLARE’ was discovered by the inventor, Renee O'Connell, in March 2015, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘SOLAR FLARE’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings, Tacisedum ‘SOLAR FLARE’ 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 ‘SOLAR FLARE’ 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 ‘SOLAR FLARE’. These characteristics in combination distinguish ‘SOLAR FLARE’ as a new and distinct Tacisedum cultivar:

    • 1. Tacisedum ‘Solar Flare’ displays an unusual copper-pink leaf margin, a condition accentuated by bright light.
    • 2. Tacisedum ‘Solar Flare’ offsets freely to produce an attractive, compact cluster.
    • 3. Tacisedum ‘Solar Flare’ produces sprays of larger pink flowers April through June.
    • 4. Tacisedum ‘Solar Flare’ exhibits a very concentric star shaped rosette, which in combination with the copper-pink leaf margin, produces an attractive geometric rosette.

PARENTAL COMPARISON

Plants of the new cultivar are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar differ in the following;

    • 1. Tacisedum ‘Solar Flare’ exhibits a low-growing, concentric rosette, whereas the parent Sedum ‘S06’ is an upright, branching plant.
    • 2. Tacisedum ‘Solar Flare’ produces larger pink flowers, while the parent Sedum ‘S06’ produces white flowers.
    • 3. The flowers of the new cultivar Tacisedum ‘Solar Flare’ are produced April through June, whereas the flowers of the parent Sedum hybrid ‘S06’ are produced January through March.
    • 4. The parent Sedum ‘S06’ grows with a somewhat lax morphology, while the new cultivar Tacisedum ‘Solar Flare’ exhibits a low-growing, concentric rosette morphology.
    • 5. The parent Sedum ‘S06’ exhibits some orange coloring to the leaves, but without the copper-pink tinge that Tacisedum ‘Solar Flare’ displays.

Plants of the new cultivar are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar differ in the following;

    • 1. Tacisedum ‘Solar Flare’ produces pink flowers, whereas Tacitus ‘Ruby 03’ produces crimson flowers.
    • 2. Tacisedum ‘Solar Flare’ produces green leaves with copper-pink margins, particularly in bright light, whereas the green leaves of the Tacitus ‘Ruby 03’ do not exhibit marginal color, even in brighter light.
    • 3. Tacisedum ‘Solar Flare’ grows faster than Tacitus ‘Ruby 03’.
    • 4. The rosette of Tacitus ‘Ruby 03’ is approximately 7-9 cm in diameter; whereas Tacisedum ‘Solar Flare’ can produce rosettes of 12 cm diameter.

COMMERCIAL COMPARISON

Plants of the new cultivar are similar to plants of the commercial variety Tacisedum ‘Spring Glow’, U.S. Plant Pat. No. 29,463, in most horticultural characteristics, however, plants of the new cultivar differ in the following;

    • 1. Tacisedum ‘Spring Glow’ forms mounded clusters to 6″ in height and 8″ or more in diameter, whereas Tacisedum ‘Solar Flare’ displays more geometric, low-growing clusters.
    • 2. Tacisedum ‘Spring Glow’ produces clusters of lime green rosettes, blushed apically red in cooler weather, whereas Tacisedum ‘Solar Flare’ produces very concentric rosettes of olive green leaves with copper-pink margins.
    • 3. Tacisedum ‘Spring Glow’ displays dense sprays of light pink flowers, whereas Tacisedum ‘Solar Flare’ produces sprays of darker pink flowers.
    • 4. Tacisedum ‘Solar Flare’ has a shiny epidermis, whereas the epidermis of Tacisedum ‘Spring Glow’ is matte in appearance.
    • 5. The leaves of Tacisedum ‘Spring Glow’ are very thickened, and have discernable internodal distances, as compared with the more flattened, appressed leaves of Tacisedum ‘Solar Flare’.

The new cultivar ‘Solar Flare’ can be compared to the unpatented Sedum adolphi. Plants of Sedum adolphi are similar to plants of the new cultivar ‘Solar Flare’ in most horticultural characteristics. However, plants of the new cultivar ‘Solar Flare’ differ in the following:

    • 1. Sedum adolphi produces lax, pendant stems, whereas Tacisedum ‘Solar Flare’ forms very concentric, low-growing rosettes.
    • 2. Tacisedum ‘Solar Flare’ produces pink flowers whereas Sedum adolphi produces white flowers.
    • 3. Tacisedum ‘Solar Flare’ produces olive green leaves with copper-pink margins, whereas Sedum adolphi produces yellow or yellow-orange leaves.
    • 4. Tacisedum ‘Solar Flare’ flowers April through June, whereas Sedum adolphi flowers December to February.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate in full color typical of plants of Tacisedum ‘Solar Flare’ grown in a greenhouse in Vista, Calif. Age of the plant photographed is approximately 5 months from a terminal vegetative cutting. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
