Botanical designation: Brachyscome multifida.
Cultivar denomination: ‘BONBRABU’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Brachyscome plant, botanically known as Brachyscome multifida and hereinafter referred to by the name ‘Bonbrabu’.
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 Yellow Rock, New South Wales, Australia, of a proprietary selection of Brachyscome multifida identified as code number 00-90, not patented, as the female, or seed, parent with a proprietary selection of Brachyscome multifida identified as code number 00-138.3, not patented, as the male, or pollen, parent in June, 2004. 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 December, 2004.
Asexual reproduction of the new Brachyscome plant by vegetative cuttings in a controlled environment in Yellow Rock, New South Wales, Australia since January, 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 environment and cultural practices 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 ‘Bonbrabu’. These characteristics in combination distinguish ‘Bonbrabu’ as a new and distinct cultivar of Brachyscome:
- 1. Compact, upright, outwardly spreading and mounding plant habit.
- 2. Freely branching growth habit.
- 3. Uniform and early flowering habit.
- 4. Numerous large inflorescences positioned above the foliage.
- 5. Violet-colored ray florets.
- 6. Good postproduction longevity and garden performance.
Plants of the new Brachyscome differ from plants of the female parent selection in the following characteristics:
- 1. Plants of the new Brachyscome are not as compact as plants of the female parent selection.
- 2. Plants of the new Brachyscome flower earlier than plants of the female parent selection.
Plants of the new Brachyscome differ from plants of the male parent selection primarily in plant habit as plants of the male parent selection are more open than and not as mounding as 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 from plants of ‘Billabong Mauve Delight’ in the following characteristics:
- 1. Plants of the new Brachyscome were more compact than plants of ‘Billabong Mauve Delight’.
- 2. Plants of the new Brachyscome had larger leaves than plants of ‘Billabong Mauve Delight’.
- 3. Leaves of plants of the new Brachyscome were deeply pinnatifid whereas leaves of plants of ‘Billabong Mauve Delight’ were lobed.
- 4. Plants of the new Brachyscome had larger inflorescences than plants of ‘Billabong Mauve Delight’.
- 5. Plants of the new Brachyscome and ‘Billabong Mauve Delight’ differed slightly in ray floret color.
