Bidens plant named ‘Balbidsuki’

Abstract

A new and distinct cultivar of Bidens plant named ‘Balbidsuki’, characterized by its golden yellow-colored flowers, medium green-colored foliage, and minimally vigorous, compact, and mounded growth habit.

Description

Latin name of genus and species of plant claimed: Bidens ferulifolia.

Variety denomination: ‘Balbidsuki’.

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 cultivar name ‘Balbidsuki’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during July 2004. The objective of the breeding program was the development of Bidens cultivars with dark green-colored foliage and a compact to vigorous growth habit.

The new cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is Solaire ‘Bidtis-1’, U.S. Plant Pat. No. 12,280, characterized by its golden yellow-colored flowers, medium green-colored foliage, and compact-upright growth habit. The male (pollen) parent of the new cultivar is unknown. The new Bidens cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during November 2004 in a controlled environment at Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since November 2004 at Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balbidsuki’ as a new and distinct cultivar of Bidens plant:

• • 1. Golden yellow-colored flowers;
  • 2. Medium green-colored foliage; and
  • 3. Minimally vigorous, compact, and mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in growth habit. Plants of the new cultivar were selected as being more compact than the female parent.

While the female parent, Solaire ‘Bidtis-1’, is similar in comparison to the new cultivar, plants were not commercially available for a side by side comparison. Based on information in U.S. Plant Pat. No. 12,280, plants of the new cultivar differ from plants of ‘Bidtis-1’ in the following characteristics:

• • 1. Plants of the new cultivar have a stem color different from plants of ‘Bidtis-1’;
  • 2. Plants of the new cultivar have a disc floret color different from plants of ‘Bidtis-1’; and
  • 3. Plants of the new cultivar have slightly wider leaves than plants of ‘Bidtis-1’.

Of the many commercially available Bidens cultivars known to the inventor, the most similar in comparison to the new cultivar is ‘Golden Star’, U.S. Plant Pat. No. 12,589. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Golden Star’ in the following characteristics:

• • 4. Plants of the new cultivar are narrower than plants of ‘Golden Star’;
  • 5. Plants of the new cultivar have smaller leaves than plants of ‘Golden Star’; and
  • 6. Plants of the new cultivar have smaller flowers than plants of ‘Golden Star’.

In addition, plants of the new cultivar are similar in comparison to ‘California Sun’, not patented. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘California Sun’ in the following characteristics:

• • 1. Plants of the new cultivar are narrower than plants of ‘California Sun’; and
  • 2. Plants of the new cultivar have smaller flowers than plants of ‘California Sun’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balbidsuki’. The plants were grown in 4.5 inch pots for 7 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balbidsuki’.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balbidsuki’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Jun. 20, 2006 between 9:00 a.m. and 11:00 a.m. under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 4.5 inch pots for 7 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day.
