Abstract

A new cultivar of Dahlia named ‘ZONE TEN’ that is distinguishable by upright habit, mahogany-black divided leaves, and striped star-shaped blossoms with a red halo around the disk florets. In combination these traits set ‘ZONE TEN’ apart from all other existing varieties of Dahlia known to the inventor.

Description

Genus: DAHLIA.
Species variabilis.
Denomination: ‘ZONE TEN’.
BACKGROUND OF THE INVENTION
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 and will be referred to hereinafter by the cultivar name ‘ZONE TEN’. 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 ‘ZONE TEN’ is a “single” form blossom and exhibits a single row of ray florets surrounding a central cluster of disk florets.
‘ZONE TEN’ was selected as an individual seedling that resulted from deliberate cross-pollination carried out by the inventor in a cultivated area of Auckland, New Zealand. The breeding began in 2001 by crossing an individual Dahlia variabilis ‘Scarlet Fern’ (unpatented) as the female parent and an individual Dahlia variabilis from experimental F1 Lines as the male parent. The female parent was planted in association with Dahlia plants that exhibited similar characteristics. Seed was collected from the female parent and coded as 71333/01, then sown with the intention of making a selection from the seedlings that resulted.
‘ZONE TEN’ was selected in 2002 based on the criteria of inflorescence color and flower markings. Selection was conducted by the inventor, in Auckland, New Zealand. The unique traits that distinguish the new Dahlia variety named ‘ZONE TEN’ from other varieties of the same genus, are mahogany-black divided leaves and profusions of striped star-shaped blossoms. The new Dahlia named ‘ZONE TEN’ is distinguishable from the parents by striped blossoms with a red halo around the disk florets.
‘ZONE TEN’ exhibits upright habit, large mahogany-black buds, dark purple stems, and mahogany-black divided leaves. The inflorescences of ‘ZONE TEN’ are fragrant, showy, and striped with a red halo around the disk florets bloom in summer and fall. Cultural conditions include full sun, regular water and rich well-draining potting soil. ‘ZONE TEN’ is hardy to USDA Zone 8 and grows to 0.9 m. in height and 0.9 m. in width at maturity.
The first asexual reproduction of ‘ZONE TEN’ was conducted in 2004 in Auckland, New Zealand. The method of asexual propagation utilized was tissue culture. 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 ‘ZONE TEN’. These traits in combination distinguish ‘ZONE TEN’ from all other existing varieties of Dahlia known to the inventor. ‘ZONE TEN’ 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. ‘ZONE TEN’ exhibits upright habit.
    • 2. ‘ZONE TEN’ exhibits mahogany-black divided leaves.
    • 3. ‘ZONE TEN’ is grown for use in mixed combinations, beds and the landscape.
    • 4. ‘ZONE TEN’ exhibits large mahogany-black buds and dark purple stems.
    • 5. ‘ZONE TEN’ exhibits fragrant striped star-shaped blossoms with a red halo around the disk florets.
    • 6. ‘ZONE TEN’ blooms summer and fall.
    • 7. ‘ZONE TEN’ grows to 0.9 m in height and 0.9 m in width at maturity.
    • 8. ‘ZONE TEN’ is hardy to USDA Zone 8.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings labeled FIG. 1 and FIG. 2 illustrate the overall appearance of the new Dahlia cultivar named ‘ZONE TEN’ 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 the new Dahlia variety named ‘ZONE TEN’.
The drawing labeled FIG. 1 depicts the entire plant in bloom from a side perspective.
