Abstract

A new and distinct cultivar of Brachycome plant named `Compact Amethyst`, characterized by its compact and outwardly spreading growth habit; very freely branching plant habit, plants do not require pinching; large number of inflorescences that are about 1.8 cm in diameter, with dark lavender ray florets; long peduncles that hold inflorescences above or beyond the foliage; and good weather tolerance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Brachycome plant, botanically known as Brachycome hybrid and referred to by the cultivar name `Compact Amethyst`.
The new Brachycome is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the program is to create new compact Brachycome cultivars that flower early, are easy to propagate, have uniform plant habit, are tolerant to temperature extremes, and have inflorescences with attractive ray floret color.
The new Brachycome originated from a cross by the Inventor in 1994 of the Brachycome hybrid cultivar `Billabong Bright Eyes` (disclosed in U.S. Plant Pat. No. 10,192), as the female, or seed, parent with the nonpatented Brachycome hybrid cultivar `Break O Day` as the male, or pollen, parent. The cultivar `Compact Amethyst` was discovered and selected by the Inventor in 1996 as a flowering plant within the progeny of the stated cross in a controlled environment in Cobbitty, New South Wales, Australia.
Asexual reproduction of the new Brachycome by terminal cuttings taken in a controlled environment in Cobbitty, New South Wales, 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 `Compact Amethyst` and distinguish `Compact Amethyst` as a new and distinct cultivar:
1. Compact and outwardly spreading growth habit.
2. Very freely branching plant habit, plants do not require pinching.
3. Very floriferous with numerous inflorescences that are about 1.8 cm in diameter, with dark lavender ray florets.
4. Long peduncles that hold inflorescences above or beyond the foliage.
5. Good weather tolerance.
Compared to plants of the female parent, the cultivar `Billabong Bright Eyes`, plants of the new Brachycome are larger, more vigorous, have larger inflorescences and darker ray floret color.
Compared to plants of the male parent, the cultivar `Break O Day`, plants of the new Brachycome are more spreading, have lighter foliage color and paler ray floret color.
Plants of the new Brachycome can be compared to nonpatented Brachycome hybrid cultivar `Amethyst`. However, in side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Brachycome are more spreading, are more basally and freely branching and are more floriferous than plants of the cultivar `Amethyst`.
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 `Compact Amethyst`.
The top of the photograph on the second sheet comprises a close-up view of typical developing inflorescences of `Compact Amethyst` from bud stage (left) to fully opened inflorescence (right).
The bottom of the photograph on the second sheet comprises a close-up view of typical developing leaves `Compact Amethyst` from bud stage (right) to fully developed leaf (left). Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
