Description

Botanical classification/cultivar designation: Chrysanthemum leucanthemum cultivar Angel.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Leucanthemum plant, botanically known as Chrysanthemum leucanthemum and hereinafter referred to by the name ‘Angel’.
The new Leucanthemum is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create compact Leucanthemum cultivars with anemone-type inflorescences.
The new Leucanthemum originated from a cross-pollination made by the Inventor in 1997, in Cobbitty, New South Wales, Australia, of a proprietary selection of Chrysanthemum leucanthemum identified as code number Dx97.12.4, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum leucanthemum identified as code number Dx97.12.8, not patented, as the male, or pollen, parent. The new Leucanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Cobbitty, New South Wales, Australia. The selection of this plant was based on its compact plant habit and anemone inflorescence form.
Asexual reproduction of the new Leucanthemum by vegetative tip cuttings was first conducted in Cobbitty, New South Wales, Australia in 1997. Asexual reproduction by cuttings has shown that the unique features of this new Leucanthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Angel has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Angel’. These characteristics in combination distinguish ‘Angel’ as a new and distinct Leucanthemum:
1. Upright, compact and uniform plant habit.
2. Early flowering habit.
3. Anemone-type inflorescences.
4. White-colored ray florets and greenish yellow to white-colored disc florets.
5. Good garden performance.
Compared to plants of the female parent selection, plants of the new Leucanthemum are more compact and flower earlier. In addition, plants of the female parent selection have single-type inflorescences. Compared to plants of the male parent selection, plants of the new Leucanthemum are more compact. In addition, plants of the male parent selection have single-type inflorescences.
Plants of the new Leucanthemum can be compared to plants of the Leucanthemum cultivar Darling Daisy, not patented. In side-by-side comparisons conducted by the Inventor in Cobbitty, New South Wales, Australia, plants of the new Leucanthemum differed from plants of the cultivar Darling Daisy in the following characteristics:
1. Plants of the new Leucanthemum had longer leaves than plants of the cultivar Darling Daisy.
2. Plants of the new Leucanthemum had larger inflorescences than plants of the cultivar Darling Daisy.
3. Plants of the new Leucanthemum had anemone-type inflorescences whereas plants of the cultivar Darling Daisy had single-type inflorescences.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Leucanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Leucanthemum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Angel’ grown in a container.
The photograph at the bottom of the sheet comprises a close-up view of a typical inflorescence bud, a typical opened inflorescence and the upper and lower surfaces of typical leaves of ‘Angel’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice during the winter and spring in a polycarbonate-covered greenhouse with day temperatures ranging from 18 to 24° C., night temperatures ranging from 16 to 18° C. and light levels ranging from 4,000 to 8,000 foot-candles. Unrooted cuttings were directly planted in 15- cm containers and grown for about 13 weeks.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
