Abstract

A new and distinct cultivar of Bidens plant named ‘Dobibitora’, characterized by its compact, semi-upright to trailing and mounding plant habit; moderately vigorous growth habit; freely branching habit; early and freely flowering habit; large inflorescences with bright yellow, yellow orange and orange-colored ray florets and yellow to yellow orange-colored disc florets; and strong and flexible peduncles that hold the inflorescences above and beyond the foliar plane.

Description

Botanical designation: Bidens ferulifolia.
Cultivar denomination: ‘DOBIBITORA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens ferulifolia and hereinafter referred to by the name ‘Dobibitora’.
The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact and early-flowering Bidens plants with numerous large and attractive inflorescences.
The new Bidens plant originated from a cross-pollination made by the Inventor in Rheinberg, Germany in July, 2015 of a proprietary selection of Bidens ferulifolia identified as code number BB14-001214-002, not patented, as the female, or seed, parent with a proprietary selection of Bidens ferulifolia identified as code number BB14-001114-003, not patented, as the male, or pollen, parent. The new Bidens 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 Rheinberg, Germany in May, 2017.
Asexual reproduction of the new Bidens plant by vegetative terminal cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2017 has shown that the unique features of this new Bidens plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Bidens 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 ‘Dobibitora’. These characteristics in combination distinguish ‘Dobibitora’ as a new and distinct Bidens plant:
    • 1. Compact, semi-upright to trailing and mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Early and freely flowering habit.
    • 5. Large inflorescences with bright yellow, yellow orange and orange-colored ray florets and yellow to yellow orange-colored disc florets.
    • 6. Strong and flexible peduncles that hold the inflorescences above and beyond the foliar plane.
Plants of the new Bidens differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Bidens are more compact than plants of the female parent selection.
    • 2. Plants of the new Bidens have larger inflorescences than plants of the female parent selection.
Plants of the new Bidens differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Bidens are more compact than plants of the male parent selection.
    • 2. Plants of the new Bidens have broader leaves than plants of the male parent selection.
    • 3. Plants of the new Bidens flower earlier than plants of the male parent selection.
Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘Florbikano’, disclosed in U.S. Plant Pat. No. 25,087. In side-by-side comparisons, plants of the new Bidens differ from plants of ‘Florbikano’ in the following characteristics:
    • 1. Plants of the new Bidens are more compact than and not as vigorous as plants of ‘Florbikano’.
    • 2. Plants of the new Bidens have broader leaves than plants of ‘Florbikano’.
    • 3. Plants of the new Bidens flower earlier than plants of ‘Florbikano’.
    • 4. Plants of the new Bidens are more freely flowering than plants of ‘Florbikano’.
    • 5. Plants of the new Bidens and ‘Florbikano’ differ in ray and disc floret color as plants of ‘Florbikano’ have yellow orange and dark orange bi-colored ray florets and bright yellow-colored disc florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of the new Bidens 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 Bidens plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Dobibitora’ grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and measurements describe plants grown in 22-cm containers during the spring and early summer in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Bidens production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were 13 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
