Abstract

A new and distinct cultivar of Bidens plant named ‘SUNBIDEV 10’, characterized by its compact, upright to somewhat outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; year-round flowering habit; large inflorescences with red and orange bi-colored ray florets; and tolerance to rain and low and high temperatures.

Description

Botanical designation: Bidens ferulifolia.

Cultivar denomination: ‘SUNBIDEV 10’.

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 ‘SUNBIDEV 10’.

The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Fukaya, Saitama, Japan. The objective of the breeding program is to create new compact and mounding Bidens plants with year-round flowering habit and numerous inflorescences with red and orange-colored ray florets.

The new Bidens plant originated from a cross-pollination made by the Inventor in Fukaya, Saitama, Japan in April, 2019 of a proprietary selection of Bidens ferulifolia identified as code number 14-9-3, not patented, as the female, or seed parent with a proprietary selection of Bidens ferulifolia identified as code number 17-9-1, 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 Fukaya, Saitama, Japan in March, 2020.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Fukaya, Saitama, Japan since December, 2020 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 ‘SUNBIDEV 10’. These characteristics in combination distinguish ‘SUNBIDEV 10’ as a new and distinct Bidens plant:

• • 1. Compact, upright to somewhat outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Year-round flowering habit.
  • 6. Large inflorescences with red and orange bi-colored ray florets.
  • 7. Tolerance to rain and low and high temperatures.

Plants of the new Bidens differ primarily from plants of the female parent selection in growth 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 the following characteristics:

• • 1. Plants of the new Bidens are more compact than plants of the male parent selection.
  • 2. Inflorescences of plants of the new Bidens have more ray florets than inflorescences of plants of the male parent selection.

Plants of the new Bidens can be compared to plants of Bidens ferulifolia ‘Sunbidevb 2’, disclosed in U.S. Plant Pat. No. 27,703. In side-by-side comparisons, plants of the new Bidens differ primarily from plants of ‘Sunbidevb 2’ in the following characteristics:

• • 1. Plants of the new Bidens are shorter and not as broad as plants of ‘Sunbidevb 2’.
  • 2. Plants of the new Bidens have shorter, broader and darker green-colored leaves than plants of ‘Sunbidevb 2’.
  • 3. Plants of the new Bidens have larger inflorescences than plants of ‘Sunbidevb 2’.
  • 4. Plants of the new Bidens have red and orange bi-colored ray florets whereas plants of ‘Sunbidevb 2’ have yellow orange and bright orange red-colored ray florets.
  • 5. Plants of the new Bidens have shorter peduncles than plants of ‘Sunbidevb 2’.
