Description

Genus: DAHLIA.

Species: variabilis.

Denomination: ‘MYSTIC WONDER’.

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(e) of U.S. Provisional Application No. 61/465,517 filed on Mar. 21, 2011 entitled DAHLIA plant named ‘MYSTIC WONDER’.

The present invention relates to a new and distinct cultivar of dahlia grown for use in mixed combinations, beds and the landscape. The new invention is known botanically as Dahlia variabilis and will be referred to hereinafter by the cultivar name ‘MYSTIC WONDER’. The specific epithet variabilis represents a hybrid seedling line that came from crossing various original wild species in the early 1800's, and refers to the species' wide range of inflorescence color and shapes. Dahlia is in the family Compositae. The inflorescence of ‘MYSTIC WONDER’ is a “single” form blossom and exhibits a single row of ray florets surrounding a central cluster of disk florets.

‘MYSTIC WONDER’ was selected as a seedling that resulted from the controlled cross-pollination carried out by the inventor in a cultivated area of Auckland, New Zealand. The breeding began in 1995 by crossing an individual plant Dahlia variabilis Selection ‘71509/01’ (unpatented) as the female parent and an individual of Dahlia variabilis ‘ZONE TEN’ (U.S. Plant Pat. No. 19,885) as the male parent. Seed was collected from the female parent and coded as 71762/01, then sown with the intention of making a selection from the seedlings that resulted.

‘MYSTIC WONDER’ was selected in 2008 based on the criteria of leaf color, leaf shape, plant height, self supporting plants, single type of inflorescence and inflorescence color. Selection was conducted by the inventor, in Auckland, New Zealand. The unique traits that distinguish ‘MYSTIC WONDER’ from other varieties of Dahlia known to the inventor are glossy mahogany-black divided leaves and profusions of rich velvety textured rich red inflorescences with dark central discs. ‘MYSTIC WONDER’ is distinguishable from the parents predominantly by inflorescence and foliage color. The inflorescences of Selection ‘71509/01’ are striped and mauve in color. The inflorescences of ‘ZONE TEN’ (U.S. Plant Pat. No. 19,885) are striped and mauve in color, the plant is shorter in height and the foliage is less divided.

‘MYSTIC WONDER’ exhibits a compact rounded habit, velvety textured rich red inflorescences with dark central discs, glossy mahogany-black foliage and dark purple-brown stems. The large single type inflorescences bloom in summer and fall. Cultural conditions include full sun, regular water and rich well-draining potting soil. ‘MYSTIC WONDER’ is hardy to USDA Zone 9 and grows to 79 cm in height and 61 cm in width at maturity.

The variety of Dahlia which is considered by the inventor to most closely resemble ‘MYSTIC WONDER’ is Dahlia ‘MYSTIC ENCHANTMENT’ (U.S. Plant Pat. No. 23,332). The inflorescence of ‘MYSTIC ENCHANTMENT’ is scarlet while the inflorescence of ‘MYSTIC WONDER’ is a rich velvety textured red. The inflorescences of ‘MYSTIC ENCHANTMENT’ are larger in size than ‘MYSTIC WONDER’. ‘MYSTIC ENCHANTMENT’ has a taller and more compact habit than ‘MYSTIC WONDER’.

The first asexual reproduction of ‘MYSTIC WONDER’ was conducted in 2008 in Auckland, New Zealand. The method of asexual propagation utilized was softwood cuttings from the tuber in year two and tissue culture thereafter. Since that time under careful observation, the distinguishing characteristics have been determined stable, uniform, and to be reproduced true to type in subsequent generations of asexual propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Dahlia cultivar named ‘MYSTIC WONDER’. These traits in combination distinguish ‘MYSTIC WONDER’ from all other existing varieties of Dahlia known to the inventor. ‘MYSTIC WONDER’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

    • 1. ‘MYSTIC WONDER’ exhibits compact rounded habit.
    • 2. ‘MYSTIC WONDER’ exhibits glossy mahogany-black divided leaves and dark purple-brown stems.
    • 3. ‘MYSTIC WONDER’ is grown for use in mixed combinations, beds and the landscape.
    • 4. ‘MYSTIC WONDER’ exhibits large velvety textured rich red single type inflorescences with dark central discs.
    • 5. ‘MYSTIC WONDER’ blooms summer and fall.
    • 6. ‘MYSTIC WONDER’ grows to 79 cm in height and 61 cm in width at maturity
    • 7. ‘MYSTIC WONDER’ is hardy to USDA Zone 9.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings labeled FIG. 1 and FIG. 2 illustrate the overall appearance of ‘MYSTIC WONDER’ showing the colors as true as is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describes the actual colors of ‘MYSTIC WONDER’.

The drawing labeled FIG. 1 depicts the entire plant in bloom.

The drawing labeled FIG. 2 depicts a close-up view of an inflorescence.

The drawings were made using conventional techniques and although inflorescence and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.

 BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Dahlia cultivar named ‘MYSTIC WONDER’. Observations, measurements, values and comparisons were collected in Santa Barbara, Calif. from a 9 month old plant grown in the landscape. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. Growing requirements are similar to the species.
