Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘LILAC FOX’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida, typically grown as a cut flower and hereinafter referred to by the name ‘Lilac Fox’.

The new Dahlia plant is a naturally-occurring branch mutation of Dahlia hybrida ‘Zundert Mystery Fox’, not patented. The new Dahlia plant was discovered and selected by the Inventor on a single flowering plant within a population of plants of ‘Zundert Mystery Fox’ in a controlled outdoor nursery environment in Lisse, The Netherlands in 2007.

Asexual reproduction of the new Dahlia plant by cuttings since the spring of 2008 in a controlled greenhouse environment in Lisse, The Netherlands, has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘Lilac Fox’. These characteristics in combination distinguish ‘Lilac Fox’ as a new and distinct Dahlia plant:

    • 1. Upright plant habit.
    • 2. Vigorous growth habit.
    • 3. High cut flower production.
    • 4. Freely flowering habit.
    • 5. Spherical decorative-type inflorescence form with red purple-colored ray florets held on strong and straight flower stems.
    • 6. Good keeping quality.

Plants of the new Dahlia differ primarily from plants of the parent, ‘Zundert Mystery Fox’ primarily in ray floret color as plants of ‘Zundert Mystery Fox’ has salmon orange-colored ray florets.

Plants of the new Dahlia can be compared to plants of the Dahlia hybrida ‘Karma Lagoon’, disclosed in U.S. Plant Pat. No. 11,346. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of ‘Karma Lagoon’ in the following characteristics:

    • 1. Plants of the new Dahlia produced more flowering stems than plants of ‘Karma Lagoon’.
    • 2. Plants of the new Dahlia had green-colored leaves whereas plants of ‘Karma Lagoon’ had leaves that tended to bronze.
    • 3. Inflorescences of plants of the new Dahlia were more spherical than inflorescences of plants of ‘Karma Lagoon’.
    • 4. Plants of the new Dahlia and ‘Karma Lagoon’ differed in ray floret color as plants of ‘Karma Lagoon’ had purple violet-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Dahlia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia plant.

The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Lilac Fox’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Lilac Fox’.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations and measurements describe plants grown during the summer and autumn in ground beds in an outdoor nursery in Lisse, The Netherlands and under cultural practices typical of commercial Dahlia production. During the production of the plants, day temperatures ranged from 10° C. to 25° C. and night temperatures ranged from 8° C. to 20° C. Plants were pinched one time about three weeks after planting. Plants were 14 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
