Bidens plant named ‘BID 719’

Abstract

A new and distinct cultivar of Bidens plant named ‘BID 719’, characterized by its semi-upright, outwardly spreading to somewhat trailing plant habit; vigorous growth habit; freely flowering habit; large inflorescences with bright yellow-colored ray florets; and strong peduncles that hold the inflorescences above and beyond the foliar plane.

Description

Botanical designation: Bidens triplinervia×Bidens ferulifolia.

Cultivar denomination: ‘BID 719’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens triplinervia×Bidens ferulifolia, and hereinafter referred to by the name ‘BID 719’.

The new Bidens is a product of a planned breeding program conducted by the Inventor in Bolzano, Italy. The objective of the breeding program was to develop new Bidens plants with attractive inflorescences with numerous ray florets.

The new Bidens plant originated from a cross-pollination made by the Inventor in Bolzano, Italy in 2007 of an unnamed selection of Bidens triplinervia, not patented, as the female, or seed, parent with Bidens ferulifolia ‘Peters Goldteppich’, disclosed in U.S. Plant Pat. No. 12,880, 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 grown in a controlled environment in Bolzano, Italy in August, 2007.

Asexual reproduction of the new Bidens by vegetative cuttings in a controlled environment in Bolzano, Italy since November, 2007, 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 environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘BID 719’. These characteristics in combination distinguish ‘BID 719’ as a new and distinct cultivar of Bidens plant:

• • 1. Semi-upright, outwardly spreading to somewhat trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely flowering habit.
  • 4. Large inflorescences with bright yellow-colored ray florets.
  • 5. Strong peduncles that hold the inflorescences above and beyond the foliar plane.

Plants of the new Bidens differ from plants of the female parent, the unnamed selection of Bidens triplinervia, in the following characteristics:

• • 1. Plants of the new Bidens have larger and darker green-colored leaves than plants of the female parent selection.
  • 2. Plants of the new Bidens have larger inflorescences than plants of the female parent selection.
  • 3. Inflorescences of plants of the new Bidens have more ray florets than inflorescences of plants of the female parent selection.

Plants of the new Bidens differ from plants of the male parent, ‘Peters Goldteppich’, in the following characteristics:

• • 1. Young plants of the new Bidens are more upright than young plants of ‘Peters Goldteppich’.
  • 2. Inflorescences of plants of the new Bidens have more ray florets than inflorescences of plants of ‘Peters Goldteppich’.

Plants of the new Bidens can be compared to plants of ‘Bidcomtis’, disclosed in U.S. Plant Pat. No. 17,326. In side-by-side comparisons conducted in Bolzano, Italy, plants of the new Bidens differed from plants of ‘Bidcomtis’ in the following characteristics:

• • 1. Young plants of the new Bidens were more upright than young plants of ‘Bidcomtis’.
  • 2. Inflorescences of plants of the new Bidens had more ray florets than inflorescences of plants of ‘Bidcomtis’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in a polyethylene-covered greenhouse in Bonsall, Calif. and under conditions and practices which approximate those generally used in commercial Bidens production. During the production of the plants, day temperatures ranged from about 26° C. to 29° C., night temperatures ranged from 18° C. to 21° C. and light levels ranged from 8,000 to 10,000 foot-candles. Plants were pinched one time and were about 25 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
