Abstract

A new and distinct cultivar of Bidens plant named ‘Koibid1510’, characterized by its compact, upright to outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; and single-type inflorescences with bright yellow and dark greyed orange bi-colored ray florets and yellow green-colored disc florets.

Description

Botanical designation: Bidens ferulifolia.

Cultivar denomination: ‘KOIBID1510’.

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 ‘Koibid1510’.

The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Okayama-ken, Japan. The objective of the breeding program is to create new freely-branching Bidens plants with unique ray floret coloration.

The new Bidens plant originated from a self-pollination made by the Inventor in Okayama-ken, Japan in January, 2011 of Bidens ferulifolia ‘K-1105’, not patented. The new Bidens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Okayama-ken, Japan in May, 2011.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Okayama-ken, Japan since June, 2011 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 ‘Koibid1510’. These characteristics in combination distinguish ‘Koibid1510’ as a new and distinct Bidens plant:

- 1. Compact, upright to outwardly spreading and mounding plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Freely flowering habit.
- 5. Long flowering period.
- 6. Single-type inflorescences with bright yellow and dark greyed orange bi-colored ray florets and yellow green-colored disc florets.

Plants of the new Bidens differ primarily from plants of the parent, ‘K-1105’ in growth habit as plants of the new Bidens are more vigorous and larger than plants of ‘K-1105’. In addition, plants of the new Bidens and ‘K-1105’ differ in ray floret color as plants of ‘K-1105’ have deep red-colored ray florets.

Plants of the new Bidens can be compared to plants of Bidens triplinervia ‘KOIBID1346’, disclosed in U.S. Plant patent application Ser. No. 14/756,434 (abandoned). In side-by-side comparisons, plants of the new Bidens differ primarily from plants of ‘KOIBID1346’ in the following characteristics:

- 1. Plants of the new Bidens are more compact than and not as vigorous as plants of ‘KOIBID1346’.
- 2. Plants of the new Bidens have slightly larger inflorescences than plants of ‘KOIBID1346’.
- 3. Plants of the new Bidens have shorter peduncles than plants of ‘KOIBID1346’.

Plants of the new Bidens can also be compared to plants of Bidens ferulifolia ‘Beedance Painted Red’, not patented. In side-by-side comparisons, plants of the new Bidens differ primarily from plants of ‘Beedance Painted Red’ in the following characteristics:

- 1. Plants of the new Bidens are more vigorous than plants of ‘Beedance Painted Red’.
- 2. Ray florets of plants of the new Bidens are more narrow than ray florets of plants of ‘Beedance Painted Red’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter in 11.5-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Bidens production.
