USPP21447P2 - Brachycome plant named ‘MM001’ - Google Patents

Abstract

A new and distinct cultivar of Brachycome plant named ‘MM001’, characterized by its compact and mounding plant habit; freely branching growth habit; freely flowering habit; large inflorescences positioned just above the foliage; violet-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Brachycome angustifolia.

Cultivar denomination: ‘MM001’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Brachycome plant, botanically known as Brachycome angustifolia and hereinafter referred to by the name ‘MM001’.

The new Brachycome plant is a product of a controlled breeding program conducted by the Inventor in Cranbourne, Victoria, Australia.

The objective of the breeding program is to create new compact Brachycome plants with large inflorescences and peduncles.

The new Brachycome plant originated from a cross-pollination in Cranbourne, Victoria, Australia, of an unnamed proprietary selection of Brachycome angustifolia, not patented, as the female, or seed, parent with Brachycome angustifolia ‘Billabong Mauve Delight’, disclosed in U.S. Plant Pat. No. 10,889, as the male, or pollen, parent. The new Brachycome 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 Cranbourne, Victoria, Australia.

Asexual reproduction of the new Brachycome plant by vegetative cuttings in a controlled environment in Cranbourne, Victoria, Australia has shown that the unique features of this new Brachycome plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Brachycome 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 ‘MM001’. These characteristics in combination distinguish ‘MM001’ as a new and distinct cultivar of Brachycome:

• • 1. Compact and mounding plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Large inflorescences positioned just above the foliage.
  • 5. Violet-colored ray florets.
  • 6. Good postproduction longevity.

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

• • 1. Plants of the new Brachycome have smaller leaves than of the female parent selection.
  • 2. Plants of the new Brachycome have smaller inflorescences than plants of the female parent selection.

Plants of the new Brachycome differ from plants of the male parent, ‘Billabong Mauve Delight’, in the following characteristics:

• • 1. Plants of the new Brachycome are taller and more mounding than plants of ‘Billabong Mauve Delight’.
  • 2. Plants of the new Brachycome are more densely foliated and have larger leaves than plants of ‘Billabong Mauve Delight’.
  • 3. Plants of the new Brachycome flower earlier than plants of ‘Billabong Mauve Delight’.
  • 4. Plants of the new Brachycome have larger inflorescences than plants of ‘Billabong Mauve Delight’.

Plants of the new Brachycome can also be compared to plants of the Brachycome multifida ‘Metallic Blue’, disclosed in U.S. Plant Pat. No. 13,692. In side-by-side comparisons conducted in Cranbourne, Victoria, Australia, plants of the new Brachycome differed from plants of ‘Metallic Blue’ in the following characteristics:

• • 1. Plants of the new Brachycome were more compact and more mounding than plants of ‘Metallic Blue’.
  • 2. Plants of the new Brachycome had broader leaves than plants of ‘Metallic Blue’.
  • 3. Plants of the new Brachycome were more freely flowering than plants of ‘Metallic Blue’.
  • 4. Plants of the new Brachycome had shorter peduncles than plants of ‘Metallic Blue’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Brachycome plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Brachycome.

The photograph on the first sheet comprises a top perspective view of a typical flowering plant of ‘MM001’ grown in a container.

The photograph on the second sheet is a close-up view of typical inflorescences and leaves of ‘MM001’.

DETAILED BOTANICAL DESCRIPTION
