Brachycome plant named `City Lights`

Abstract

A new and distinct cultivar of Brachycome plant named `City Lights`, characterized by its compact and outwardly spreading growth habit; very freely branching plant habit, plants do not require pinching; numerous and showy inflorescences with lavender ray florets that are about 2.5 cm in diameter; and long peduncles that hold inflorescences above or beyond the foliage.

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 City Lights.

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, and have large inflorescences with attractive ray floret color.

The new Brachycome originated from a cross by the Inventor in 1995 of the Brachycome multifida cultivar Billabong Bright Eyes (disclosed in U.S. Plant Pat. No. 10,192), as the female, or seed, parent with an unidentified selection of Brachycome segmentosa as the male, or pollen, parent. The cultivar City Lights 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, saylength and light intensity, without, however, any variance in genotype.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of `City Lights` and distinguish `City Lights` 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. Numerous and showy inflorescences with lavender ray florets that are about 2.5 cm in diameter.

4. Long peduncles that hold inflorescences above or beyond the foliage.

Compared to plants of the female parent, the cultivar Billabong Bright Eyes, plants of the new Brachycome are larger, more vigorous and have larger inflorescences.

Compared to plants of the male parent, an unidentified selection of Brachycome segmentosa, plants of the new Brachycome are denser, more spreading and have finer foliage. In addition, ray floret color of plants of the male parent is white.

Plants of the new Brachycome can be compared to nonpatented species Brachycome multifida, common name Hawkesbury River Daisy. However, in side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Brachycome differ from plants of Hawkesbury River Daisy in the following characteristics:

1. Plants of the new Brachycome have lighter and brighter green foliage color than plants of Hawkesbury River Daisy.

2. Plants of the new Brachycome have larger inflorescences than plants of Hawkesbury River Daisy.

3. Ray floret color of plants of the new Brachycome is paler than ray floret color of plants of Hawkesbury River Daisy.

4. Plants of the new Brachycome have longer peduncles than plants of Hawkesbury River Daisy.
