Abstract

A new and distinct cultivar of Brachycome plant named `Lemon Twist`, characterized by its compact and spreading growth habit; very freely branching plant habit, plants do not require pinching; numerous inflorescences with yellow ray florets; and erect peduncles that hold inflorescences above the foliage.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Brachycome plant, botanically known as Brachycome multifida var. dilatata×Brachycome curvicarpa and referred to by the cutlivar name `Lemon Twist`. The new Brachycome is marketed under the trade name Mini Yellow.
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 an unidentified selection of Brachycome multifida var. dilatata, as the female, or seed, parent with an unidentified selection of Brachycome curvicarpa as the male, or pollen, parent. The cultivar `Lemon Twist` 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 `Lemon Twist` and distinguish `Lemon Twist` as a new and distinct cultivar:
1. Compact and spreading growth habit.
2. Very freely branching plant habit, plants do not require pinching.
3. Numerous inflorescences with yellow ray florets.
4. Erect peduncles that hold inflorescences above the foliage.
Compared to plants of the female parent, an unidentified selection of Brachycome multifida var. dilatata, plants of the new Brachycome are more compact and differ in ray floret color.
Compared to plants of the male parent, an unidentified selection of Brachycome curvicarpa, plants of the new Brachycome are more compact, more spreading, and have shorter peduncles.
Plants of the new Brachycome can be compared to the Brachycome hybrid cultivar `Sunburst`, disclosed in U.S. Plant Pat. No. 10,203. However, in side-by-side comparisions conducted in Victoria, Australia, plants of the new Brachycome differ from plants of the cultivar `Sunburst` in the following characteristics:
1. Plants of the new Brachycome are more compact than plants of the cultivar `Sunburst`.
2. Plants of the new Brachycome have smaller leaves that are not as deeply lobed than plants of the cultivar `Sunburst`.
3. Plants of the new Brachycome have smaller inflorescences than plants of the cultivar `Sunburst`.
4. Ray floret color of plants of the new Brachycome is darker yellow than ray floret color of plants of the cultivar `Sunburst`.
5. Plants of the new Brachycome have shorter peduncles than plants of the cultivar `Sunburst`.
Plants of the new Brachycome can also be compared to the nonpatented Brachycome hybrid cultivar `Lemon Drops`. However, in-side-by-side comparisions conducted in Victoria, Australia, plants of the new Brachycome differ from plants of the cultivar `Lemon Drops` in the following characteristics:
1. Plants of the new Brachycome are more compact than plants of the cultivar `Lemon Drops`.
2. Plants of the new Brachycome have larger inflorescences than plants of the cultivar `Lemon Drops`.
3. Ray floret color of plants of the new Brachycome is brighter yellow than ray floret color of plants of the cultivar `Lemon Drops`.
4. Ray floret color of plants of the new Brachycome does not fade as readily as ray floret color of plants of the cultivar `Lemon Drops`.
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 side perspective view of a typical potted plant of `Lemon Twist`.
The photograph on the second sheet comprises a close-up view of typical inflorescences of `Lemon Twist`. Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
