| Abstract: |
A new and distinct cultivar of Argyranthemum frustescens plant named `Argymidowi` characterized by its very compact plant habit, nice bright white double flower heads and floriferous character through Summer. |
| Claim: |
What is claimed is:
1. A new and distinct variety of Argyranthemum frutescens plant, named `Argymidowi,` substantially as herein illustrated and described. |
| Description: |
Latin name of the genus and species of the plant claimed: Argyranthemum frutescens.
Varietal denomination: `Argymidowi`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as Argyranthemum frutescens and hereinafter referred to by the cultivar name `Argymidowi.`
The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, The Netherlands. The new cultivar `Argymidowi` is compact with early freely flowering habit, which can be grown without growth regulators.
The new Argyranthemum originated from an open-pollination conducted in Enkhuizen, The Netherlands in 2001 of a proprietary selection of Argyranthemum frutescens identified as code number `D0039-1,` not patented, as the female, or seed, parentwith an unknown selection of Argyranthemum frutescens as the male, or pollen, parent.
The cultivar `Argymidowi` was discovered and selected as a single plant within the progeny of the stated open pollination in a controlled environment in Enkhuizen, the Netherlands in August 2002. Asexual reproduction of the new Argyranthemum byterminal cuttings in a controlled environment in Enkhuizen, The Netherlands since August 2002, has shown that the unique features of this new Argyranthemum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Argyranthemum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of `Argymidowi` and distinguish to new Argyranthemum as a new and distinct cultivar: 1. Compact plant habit. 2. Freely branching habitand short internodes; dense and bushy plant habit. 3. Early flowering habit. 4. Freely flowering habit with numerous inflorescences per plant. 5. Double flower heads. 6. Short peduncle length.

DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly fromthe color values cited in the detailed botanical description which accurately describe the colors of the new Argyranthemum.
DESCRIPTION OF THE NEW CULTIVAR
The aforementioned photographs, following detailed observations and averaged measurements describe plants of this new Marguerite Daisy plant. The data were collected from plants from asexual reproductions carried out in Enkhuizen, TheNetherlands. The plant history was taken on 28 weeks old plants, grown in the open field in Enkhuizen, The Netherlands with day temperatures ranging from 16 to 35 degrees C., and night temperatures ranging from 10 to 20 degrees C.
