Brachycome plant named `Strawberry Mousse`

- Koala Blooms Pty. Ltd.

A new and distinct Brachycome named `Strawberry Mousse`, characterized by its low-growing and spreading plant habit; fast crop time; moderate vigor; freely branching plant habit; relatively large inflorescences with pink ray florets and bright yellow-green disc florets; and long, erect peduncles that hold inflorescences above the foliage.

Description

The present invention relates to a new and distinct cultivar of Brachycome plant, botanically known as a Brachycome hybrid and referred to by the cultivar name `Strawberry Mousse`.

The new cultivar originated from a cross made by the inventor of Brachycome angustifolia, as the male or pollen parent, with Brachycome formosa, as the female or seed parent. The cultivar `Strawberry Mousse` was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Merricks, Victoria, Australia. While the plant of this disclosure has been denominated `Strawberry Mousse` for purposes of international recognition, it is contemplated that this plant will be sold under the trademark "Billabong" as "Billabong" `Strawberry Mousse` in the United States.

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

The new cultivar 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.

Compared to the parent cultivar Brachycome angustifolia, plants of the new Brachycome have larger leaves and larger inflorescences. Compared to the parent cultivar Brachycome formosa, plants of the new Brachycome are faster in growth rate, more vigorous, have longer peduncles, have pink rather than purple ray florets, and the adaxial surface of young leaves is green rather than dark purple. A detailed comparison of the differences between Brachycome formosa and the cultivar `Strawberry Mousse` appears in Chart A at the end of the specification.

The new Brachycome can also be compared to the cultivar Pink Swirl which is thought to have the same parents as the new Brachycome. In side-by-side comparisons conducted in Merricks, Victoria, Australia, under commercial conditions, plants of the new Brachycome are more vigorous, ray floret color is paler pink, and the adaxial surface of the leaves is green rather than purple.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of `Strawberry Mousse` which distinguish `Strawberry Mousse`. as a new and distinct cultivar:

1. Low-growing and spreading plant habit.

2. Fast crop time.

3. Moderate vigor.

4. Freely branching plant habit.

5. Relatively large inflorescences with pink ray florets and bright yellow-green disc florets.

6. Long, erect peduncles that hold inflorescences above the foliage.

BRIEF DESCRIPTION OF THE VIEWS OF THE DRAWING

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

The first photograph, at the top, comprises a top perspective view of a single potted plant of `Strawberry Mousse`.

The second photograph comprises a close-up view of inflorescences of plants of `Strawberry Mousse`. Floret color in the photographs may appear different from the actual floret color due to light reflectance.

The following observations, measurements, values, and comparisons describe plants grown in Merricks, Victoria, Australia, under outdoor conditions with day temperatures ranging from 10 to 30C, night temperatures ranging from 5 to 20C, and light levels ranging from 5,000 to 9,000 footcandles. Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
