Abstract

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

Description

Botanical designation: Bidens ferulifolia.
Cultivar denomination: ‘DUEBIGONZA’.
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 ‘Duebigonza’.
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 mounding Bidens cultivars with numerous large inflorescences.
The new Bidens plant originated from a cross-pollination made by the Inventor in Rheinberg, Germany in July, 2007, of a proprietary selection of Bidens ferulifolia identified as code number F-25-07, not patented, as the female, or seed, parent with a proprietary selection of Bidens ferulifolia identified as code number F-19-19, 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, 2008.
Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Rheinberg, Germany since May, 2008, 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 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 ‘Duebigonza’. These characteristics in combination distinguish ‘Duebigonza’ as a new and distinct cultivar of Bidens:
    • 1. Compact and mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Early and freely flowering habit.
    • 4. Large inflorescences with bright yellow-colored ray florets and darker yellow-colored disc florets.
    • 5. Strong 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 plant habit as plants of the new Bidens are more compact than plants of the female parent selection.
Plants of the new Bidens differ primarily from plants of the male parent selection in inflorescence size as plants of the new Bidens have larger inflorescences than plants of the male parent selection.
Plants of the new Bidens can be compared to plants of Bidens ferulifolia ‘Solaire Horizon’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Bidens differed from plants of ‘Solaire Horizon’ in the following characteristics:
    • 1. Plants of the new Bidens were more compact than plants of ‘Solaire Horizon’.
    • 2. Plants of the new Bidens had shorter intemodes than plants of ‘Solaire Horizon’.
    • 3. Plants of the new Bidens had larger inflorescences than plants of ‘Solaire Horizon’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of the new Bidens 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 Bidens plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duebigonza’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and measurements describe plants grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany under conditions and practices which approximate those generally used in commercial Bidens production. During the production of the plants, day and night temperatures averaged 18° C. and light levels were about 4,500 lux. Plants were pinched one time three weeks after planting. Plants were twelve weeks old when the photograph 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.
