Abstract

A new and distinct cultivar of Brachyscome plant named ‘Bonbra7115’, characterized by its compact and upright plant habit; freely branching growth habit, bushy growth form; numerous inflorescences positioned above the foliar plane; bright yellow-colored ray florets; and good postproduction longevity and garden performance.

Description

Botanical designation: Brachyscome×hybrida.

Cultivar denomination: ‘BONBRA7115’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Brachyscome plant, botanically known as Brachyscome×hybrida and hereinafter referred to by the name ‘Bonbra7115’.

The new Brachyscome plant is a product of a controlled breeding program conducted by the Inventor in Yellow Rock, New South Wales, Australia. The objective of the breeding program is to create new mounding Brachyscome plants with unique and attractive ray floret color.

The new Brachyscome plant originated from a cross-pollination in August, 2004 in Yellow Rock, New South Wales, Australia, of a proprietary selection of Brachyscome×hybrida identified as code number 00-127.1, not patented, as the female, or seed, parent with a proprietary selection of Brachyscome×hybrida identified as code number 00-147.6, not patented, as the male, or pollen, parent. The new Brachyscome 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 environment in Yellow Rock, New South Wales, Australia in April, 2005.

Asexual reproduction of the new Brachyscome plant by vegetative cuttings in a controlled environment in Yellow Rock, New South Wales, Australia since May, 2005, has shown that the unique features of this new Brachyscome plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Brachyscome have not been observed under all possible environmental conditions. 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 ‘Bonbra7115’. These characteristics in combination distinguish ‘Bonbra7115’ as a new and distinct Brachyscome plant:

• • 1. Compact and upright plant habit.
  • 2. Freely branching growth habit, bushy growth form.
  • 3. Numerous inflorescences positioned above the foliar plane.
  • 4. Bright yellow-colored ray florets.
  • 5. Good postproduction longevity and garden performance.

Plants of the new Brachyscome differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Brachyscome have smaller inflorescences than plants of the female parent selection.
  • 2. Plants of the new Brachyscome and the female parent selection differ in ray floret color as plants of the female parent selection have pink-colored ray florets.

Plants of the new Brachyscome differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Brachyscome are more compact and bushier than plants of the male parent selection.
  • 2. Plants of the new Brachyscome have smaller leaves than plants of the male parent selection.

Plants of the new Brachyscome can also be compared to plants of the Brachyscome angustifolia ‘Billabong Mauve Delight’, disclosed in U.S. Plant Pat. No. 10,889. In side-by-side comparisons conducted in Yellow Rock, New South Wales, Australia, plants of the new Brachyscome differed primarily from plants of ‘Billabong Mauve Delight’ in the following characteristics:

• • 1. Plants of the new Brachyscome were narrower than plants of ‘Billabong Mauve Delight’.
  • 2. Plants of the new Brachyscome had slightly smaller inflorescences than plants of ‘Billabong Mauve Delight’.
  • 3. Plants of the new Brachyscome had more ray florets per inflorescence than plants of ‘Billabong Mauve Delight’.
  • 4. Plants of the new Brachyscome and ‘Billabong Mauve Delight’ differed in ray floret color as plants of ‘Billabong Mauve Delight’ had light purple-colored ray florets.
