Description

Botanical designation: Argyranthemum x hybrida.

Cultivar denomination: ‘BONMAD 1498’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Argyranthemum plant, botanically known as Argyranthemum x hybrida and hereinafter referred to by the name ‘Bonmad 1498’.

The objective of the breeding program is to create new compact and freely flowering Argyranthemum plants with attractive floret colors and good garden performance.

The new Argyranthemum plant originated from a cross-pollination made by the Inventor in 2012 in Yellow Rock, New South Wales, Australia of a proprietary selection of Argyranthemum x hybrida identified as code number 11-316, not patented, as the female, or seed, parent with a mixture of pollen from 13 unidentified proprietary selections of Argyranthemum x hybrida, as the male, or pollen, parent. The new Argyranthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Yellow Rock, New South Wales, Australia in June, 2014.

Asexual reproduction of the new Argyranthemum plant by vegetative tip cuttings was first conducted in Yellow Rock, New South Wales, Australia in June, 2014. Asexual reproduction by cuttings has shown that the unique features of this new Argyranthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Argyranthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bonmad 1498’. These characteristics in combination distinguish ‘Bonmad 1498’ as a new and distinct Argyranthemum cultivar:

    • 1. Compact, upright, uniform and mounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Early and freely flowering habit.
    • 4. Semi-double-type inflorescences with ray florets that are initially light yellow in color with development becoming deep pink to moderately purplish pink and pale yellow in color and yellow orange-colored disc florets.
    • 5. Good garden performance.

Plants of the new Argyranthemum differ from plants of the female parent selection in ray floret color. Ray florets of plants of the new Argyranthemum are initially light yellow in color with development becoming deep pink to moderately purplish pink and pale yellow in color whereas ray florets of plants of the female parent selection are red in color.

Plants of the new Argyranthemum differ from plants of the male parent selections in ray floret color. Ray florets of plants of the new Argyranthemum are initially light yellow in color with development becoming deep pink to moderately purplish pink and pale yellow in color whereas ray florets of plants of the 13 male parent selections are either yellow, pink or red in color.

Plants of the new Argyranthemum can be compared to plants of the Argyranthemum x hybrida ‘Bonmadhopi’, not patented. In side-by-side comparisons, plants of the new Argyranthemum differ from plants of ‘Bonmadhopi’ in the following characteristics:

    • 1. Plants of the new Argyranthemum are taller and broader than plants of ‘Bonmadhopi’.
    • 2. Plants of the new Argyranthemum have smaller leaves than plants of ‘Bonmadhopi’.
    • 3. Inflorescences of plants of the new Argyranthemum are semi-double types whereas inflorescences of plants of ‘Bonmadhopi’ are single-types.
    • 4. Ray florets of plants of the new Argyranthemum are initially light yellow in color with development becoming deep pink to moderately purplish pink and pale yellow in color whereas ray florets of plants of ‘Bonmadhopi’ are red purple and white in color.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in Higashiomi, Shiga, Japan in an outdoor nursery and under conditions and practices which approximate those generally used in commercial potted Argyranthemum production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants used in the photographs were four months old and plants used for the detailed description were five months old.
