plant named ‘Fidahcali’

Abstract

A new and distinct cultivar of Dahlia plant named ‘Fidahcali’, characterized by its compact, upright, somewhat outwardly spreading and mounded plant habit; freely branching growth habit; freely flowering habit; large decorative inflorescences with red and yellow bi-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘Fidahcali’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida, and hereinafter referred to by the name ‘Fidahcali’.

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program is to create new pot-type Dahlia cultivars that have a freely branching and flowering habit, attractive ray floret coloration and good postproduction longevity.

The new Dahlia plant originated from an open-pollination in Hillegom, The Netherlands of an unnamed selection of Dahlia hybrida, not patented, as the female, or seed, parent with an unknown selection of Dahlia hybrida as the male, or pollen, parent. The new Dahlia was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Hillegom, The Netherlands.

Asexual reproduction of the new Dahlia plant by cuttings in a controlled environment in Hillegom, The Netherlands since 2006, 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. The phenotype may vary somewhat with variations in environment 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 ‘Fidahcali’. These characteristics in combination distinguish ‘Fidahcali’ as a new and distinct cultivar of Dahlia:

• • 1. Compact, upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Decorative inflorescences with red and yellow bi-colored ray florets.
  • 5. Good postproduction longevity.

Compared to plants of the female parent selection, plants of the new Dahlia differ primarily in ray floret coloration and plant shape.

Plants of the new Dahlia can be compared to plants of Dahlia hybrida ‘Lisa Dark Pink’, disclosed in U.S. Plant Pat. No. 11,780. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Dahlia differed from plants of ‘Lisa Dark Pink’ primarily in ray floret color as plants of ‘Lisa Dark Pink’ had dark pink-colored colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Dahlia plant.

The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph 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 comprises a side perspective view of a typical flowering plant of ‘Fidahcali’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and the following observations and measurements describe plants grown in a glass-covered greenhouse in De Lier, The Netherlands during the late summer and autumn and under conditions and practices which approximate those generally used in commercial Dahlia production. During the production of the plants, day and night temperatures averaged 18° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about 10 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
