Abstract

A new and distinct cultivar of Dahlia plant named ‘Ferangel’, characterized by its compact, upright and mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; and double type inflorescences with white-colored ray florets.

Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘FERANGEL’.

BACKGROUND OF THE INVENTION

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

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 strong Dahlia plants with numerous double inflorescences.

The new Dahlia plant originated from a cross-pollination in Hillegom, The Netherlands in June, 2012 of a proprietary selection of Dahlia hybrida identified as code name DEC, not patented, as the female, or seed, parent with Dahlia hybrida ‘Madahlia’, not patented, as the male, or pollen, parent. The new Dahlia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hillegom, The Netherlands in September, 2013.

Asexual reproduction of the new Dahlia plant by vegetative terminal cuttings in a controlled greenhouse environment in Hillegom, The Netherlands since October, 2013 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 combinations of 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 ‘Ferangel’. These characteristics in combination distinguish ‘Ferangel’ as a new and distinct Dahlia plant:

- 1. Compact, upright and mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark green-colored leaves.
- 5. Freely flowering habit.
- 6. Double type inflorescences with white-colored ray florets.

Compared to plants of the female parent selection, plants of the new Dahlia differ primarily in the following characteristics:

- 1. Plants of the new Dahlia are more compact than plants of the female parent selection.
- 2. Plants of the new Dahlia have smaller inflorescences than plants of the female parent selection.

Compared to plants of the male parent, ‘Madahlia’, plants of the new Dahlia differ primarily in the following characteristics:

- 1. Plants of the new Dahlia are larger than plants of the ‘Madahlia’.
- 2. Plants of the new Dahlia are more freely branching than plants of ‘Madahlia’.
- 3. Inflorescences of plants of the new Dahlia are more fully double than inflorescences of plants of ‘Madahlia’.

Plants of the new Dahlia can be compared to plants of Dahlia hybrida ‘BKDAWHT’, disclosed in U.S. Plant Pat. No. 24,919. In side-by-side comparisons, plants of the new Dahlia differ primarily from plants of ‘BKDAWHT’ in the following characteristics:

- 1. Plants of the new Dahlia are larger than plants of ‘BKDAWHT’.
- 2. Leaves of plants of the new Dahlia have more pointed apices than leaves of plants of ‘BKDAWHT’.
- 3. Inflorescences of plants of the new Dahlia are more fully double than inflorescences of plants of ‘BKDAWT’.
- 4. Stock plants of the new Dahlia produce more vegetative terminal cuttings than Stock plants of ‘BKDAWHT’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates 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 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 is a side perspective view of a typical flowering plant of ‘Ferangel’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 1.5-liter containers in a glass-covered greenhouse in DeKwakel, The Netherlands and under cultural practices typical of commercial potted Dahlia production. During the production of the plants, day temperatures ranged from 16° C. to 23° C. and night temperatures ranged from 13° C. to 18° C. Plants were 16 and 20 weeks old when the description and photograph, respectively, were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
