Abstract

A new and distinct cultivar of Bidens plant named ‘Sunbidevb 7’, characterized by its compact, upright to outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; year-round flowering habit; relatively large inflorescences with reddish orange and bright yellow bi-colored ray florets; and good garden performance.

Description

Botanical designation: Bidens ferulifolia.

Cultivar denomination: ‘SUNBIDEVB 7’.

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 ‘Sunbidevb 7’.

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 attractive inflorescences.

The new Bidens plant originated from a cross-pollination made by the Inventor in Fukaya, Saitama, Japan during the winter of 2015 of a proprietary selection of Bidens ferulifolia identified as code number 1513-2, not patented, as the female, or seed parent with a proprietary selection of Bidens ferulifolia identified as code number 2015-Y, 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 October, 2016.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Fukaya, Saitama, Japan since 2018 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 ‘Sunbidevb 7’. These characteristics in combination distinguish ‘Sunbidevb 7’ as a new and distinct Bidens plant:

• • 1. Compact, upright to outwardly spreading and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Year-round flowering habit.
  • 6. Relatively large inflorescences with reddish orange and bright yellow bi-colored ray florets.
  • 7. Good garden performance.

Plants of the new Bidens differ primarily from plants of the female parent selection in ray floret color. Plants of the new Bidens have reddish orange and bright yellow bi-colored ray florets whereas plants of the female parent selection have yellow-colored ray florets with a red-colored horizontal stripe.

Plants of the new Bidens differ primarily from plants of the male parent selection in ray floret color. Plants of the new Bidens have reddish orange and bright yellow bi-colored ray florets whereas plants of the male parent selection have yellow-colored ray florets.

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 more compact than plants of ‘Sunbidevb 2’.
  • 2. Plants of the new Bidens have smaller leaves than plants of ‘Sunbidevb 2’.
  • 3. Plants of the new Bidens have larger inflorescences than plants of ‘Sunbidevb 2’.
  • 4. Ray florets of plants of the new Bidens are reddish orange and bright yellow bi-colored whereas ray florets of plants of ‘Sunbidevb 2’ are yellow orange and bright orange red in color.
