Brachycome plant named `Happy Face Pink`

Abstract

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Brachycome plant, botanically known as Brachycome formosa.times.Brachycome segmentosa Hybrid and referred to by the cultivar name `Happy Face Pink`. The new Brachycome is marketed under the trade name Jumbo Mauve.

The new Brachycome is a product of a planned breeding program conducted by the Inventor in Park Orchards, Victoria, Australia. The objective of the program is to create new compact Brachycome cultivars with large inflorescences that are suitable for a range of climatic conditions.

The new Brachycome originated from a cross by the Inventor of the nonpatented Brachycome formosa cultivar `Pilliga Posy`, as the female, or seed, parent with an unidentified selection of Brachycome segmentosa Hybrid as the male, or pollen, parent. The cultivar `Happy Face Pink` was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Park Orchards, Victoria, Australia.

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

SUMMARY OF THE INVENTION

The new Brachycome has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of `Happy Face Pink` and distinguish `Happy Face Pink` as a new and distinct cultivar:

1. Compact and spreading growth habit.

2. Freely branching plant habit.

3. Numerous large inflorescencs with dark pink ray florets.

4. Erect peduncles that hold inflorescences above the foliage.

Compared to plants of the female parent, the cultivar `Pilliga Posy`, plants of the new Brachycome have darker green leaves with more deeply lobed margins and longer stems. Additionally plants of the cultivars `Pilliga Posy` and `Happy Face Pink` differ in ray floret color.

Compared to plants of the male parent, the unidentified selection of Brachycome segmentosa Hybrid, plants of the new Brachycome are more compact and have broader leaf lobes. Additionally plants of the unidentified selection of Brachycome segmentosa Hybrid and `Happy Face Pink` differ in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Brachycome, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a top perspective view of a typical potted plant of `Happy Face Pink`.

The photograph on the second sheet comprises a close-up view of typical inflorescences of `Happy Face Pink`. Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
