Bidens plant named `Innbid`

Abstract

A distinct cultivar of Bidens plant named `Innbid`, characterized by its uniform, compact, and freely branching growth habit; spherical plant shape; moderately vigorous growth rate; numerous inflorescences with bright yellow ray florets; and excellent garden and outdoor performance.

Description

The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens ferulifolia, and hereinafter referred to by the cultivar name `Innbid`. The new cultivar is being marketed under the name `Goldie`.

The new Bidens was discovered by the inventor in a controlled environment in Gensingen, Germany, in June, 1995, as a naturally-occurring mutation of the nonpatented Bidens ferulifolia `Goldmarie`. The new Bidens was observed as a single plant in a large population of plants of the parent cultivar. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Bidens differed from plants of the cultivar `Goldmarie` in the following characteristics:

1. Plants of the new Bidens are more uniform, compact, denser and less vigorous than plants of the cultivar `Goldmarie`.

2. Plants of the new Bidens have shorter internodes than plants of the cultivar `Goldmarie`.

3. Plants of the new Bidens have, darker green, smaller, broader and more overlapping leaflets than plants of the cultivar `Goldmarie`.

4. Inflorescences of plants of the new Bidens are smaller and have more rounded and brighter yellow ray florets than inflorescences of plants of the cultivar `Goldmarie`.

5. Inflorescences of plants of the new Bidens are closer to the foliage than inflorescences of planst of the cultivar `Goldmarie`.

Asexual reproduction of the new cultivar by terminal cuttings taken in Gensingen, Germany, has shown that the unique features of this new Bidens are stable and reproduced true to type in successive propagations.

The cultivar `Innbid` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, and fertility level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Innbid `. These characteristics in combination distinguish `Innbid` as a new distinct cultivar:

1. Uniform and compact growth habit.

2. Initially upright then outwardly spreading plant shape; eventually becoming roughly spherical.

3. Freely branching, bushy, and dense; suitable for hanging basket containers.

4. Moderately vigorous growth rate.

5. Numerous inflorescences with bright yellow ray florets that last for a long period of time.

6. Excellent garden and outdoor performance.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph at the top of the sheet comprises a top perspective view of a typical hanging basket plant of the cultivar `Innbid`.

The photograph at the bottom of the sheet comprises a close-up view of typical leaves and inflorescences of a plant of the cultivar `Innbid`.

Inflorescence and foliage colors in the photographs may appear different than the actual colors due to light reflectance.
