Argyranthemum frutescens plant named ‘Argyminpifi’

Abstract

A new and distinct cultivar of Argyranthemum frutescens plant, substantially as herein illustrated and described, characterized particularly as to novelty by its compact rounded plant habit, good field performance, dark green colored leaves, freely flowering with numerous inflorescences per plant, and daisy-type inflorescences with pink double flowered inflorescences, organized in a crumpled way.

Description

Latin name of the genus and species of the plant claimed: Argyranthemum frutescens.

Varietal denomination: ‘Argyminpifi’.

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 ‘Argyminpifi.’

The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, The Netherlands. The objective of the breeding program was to create new, compact Argyranthemums 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 2000 of a proprietary selection of Argyranthemum frutescens identified as code number ‘D0107,’ not patented, as the female, or seed, parent with an unknown selection of Argyranthemum frutescens as the male, or pollen, parent.

The cultivar ‘Argyminpifi’ 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 2001. Asexual reproduction of the new Argyranthemum by terminal cuttings in a controlled environment in Enkhuizen, The Netherlands since August 2001, 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 ‘Argyminpifi’ and distinguish to new Argyranthemum as a new and distinct cultivar:

• • 1. Compact, upright and rounded plant habit
  • 2. Freely branching habit and short internodes; dense and bushy plant habit.
  • 3. Early flowering habit
  • 4. Freely flowering habit with numerous inflorescences per plant.
  • 5. Daisy-type inflorescences with pink ray florets in double inflorescences.

Plants of the new ‘Argyminpifi’ have a more compact habit compared to their maternal parent. In addition, ‘Argyminpifi’ has a frizzled flower shape (petals of inner whorls are crumpled), wherein the maternal parent have petals of inner whorls that are straight. The maternal parent is also more vigorous than ‘Argyminpifi.’

Plants of the new Argyranthemum can be compared to plants of the cultivar ‘Summer Melody,’ ‘Argywhimi’ and ‘Summer Stars Pink.’ In side-by-side comparisons conducted in Enkhuizen, The Netherlands, plants of the new Argyranthemum differed from plants of the comparison varieties in the following characteristics:

DESCRIPTION OF THE DRAWING

The accompanying colored 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 from the 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, The Netherlands. The plant history was taken on 30 week old plants, grown in the open field in Enkhuizen, The Netherlands with day temperatures ranging from 16 to 30 degrees C., and night temperatures ranging from 10 to 16 degrees C.
