| Abstract: |

| Claim: |
It is claimed:
1. A new and distinct Argyranthemum plant named `Ohmadporm` as illustrated and described. |
| Description: |
Botanical designation:Argyranthemum.times.hybrida.
Cultivar denomination: `OHMADPORM`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Argyranthemum plant, botanically known as Argyranthemum.times.hybrida and hereinafter referred to by the name `Ohmadporm`.
The objective of the breeding program is to create new Argyranthemum cultivars with numerous inflorescences, attractive floret colors, and good garden performance.
The new Argyranthemum originated from a cross-pollination made by the Inventor in 2001 in Winmalee, New South Wales, Australia of a proprietary selection of Argyranthemum.times.hybrida identified as code number 01-233, not patented, as thefemale, or seed, parent with a proprietary selection of Argyranthemum.times.hybrida identified as code number 01-235, as the male, or pollen, parent. The new Argyranthemum was discovered and selected by the Inventor as a single flowering plant withinthe progeny of the stated open-pollination in a controlled environment in Winmalee, New South Wales, Australia.
Asexual reproduction of the new Argyranthemum by vegetative tip cuttings was first conducted in Winmalee, New South Wales, Australia in September, 2003. Asexual reproduction by cuttings has shown that the unique features of this newArgyranthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Ohmadporm have 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, anyvariance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Ohmadporm`. These characteristics in combination distinguish `Ohmadporm` as a new and distinct potted Argyranthemum cultivar. 1. Compact, uniform and mounded plant habit. 2. Freely branching and vigorous growth habit. 3. Freely flowering habit. 4. Semi-double type inflorescences with red purple-colored ray florets. 5. Good garden performance.
Plants of the new Argyranthemum differ from plants of the female parent selection in the following characteristics: 1. Plants of the new Argyranthemum have smaller leaves than plants of the female parent selection. 2. Plants of the newArgyranthemum have semi-double type inflorescences whereas plants of the female parent selection have single inflorescences. 3. Plants of the new Argyranthemum and the female parent selection differ in ray floret color as plants of the female parentselection have yellow-colored ray florets.
Plants of the new Argyranthemum differ from plants of the male parent selection in the following characteristics: 1. Plants of the new Argyranthemum have semi-double type inflorescences whereas plants of the male parent selection have singleinflorescences. 2. Plants of the new Argyranthemum and the male parent selection differ in ray floret color as plants of the male parent selection have yellow-colored ray florets.
Plants of the new Argyranthemum can be compared to plants of the Argyranthemum cultivar Ohmadsavi, disclosed in U.S. Plant Pat. No. 16,648. In side-by-side comparisons conducted in Winmalee, New South Wales, Australia, plants of the newArgyranthemum differed from plants of the cultivar Ohmadsavi in the following characteristics: 1. Plants of the new Argyranthemum were more compact than plants of the cultivar Ohmadsavi. 2. Plants of the new Argyranthemum were more freely branchingthan plants of the cultivar Ohmadsavi. 3. Plants of the new Argyranthemum had smaller leaves than plants of the cultivar Ohmadsavi. 4. Inflorescences of plants of the new Argyranthemum had more ray florets, but fewer disc florets than inflorescencesof plants of the cultivar Ohmadsavi. 5. Plants of the new Argyranthemum and the cultivar Ohmadsavi differed in ray floret coloration.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Argyranthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs maydiffer slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Argyranthemum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Ohmadporm` grown in a container.
The photograph at the bottom of the sheet is a close-up view of the typical inflorescences of `Ohmadorm`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in Higashiomi, Shiga, Japan in a greenhouse and under conditions and practices which approximate those generally used incommercial potted Argyranthemum production.
