Abstract

A new and distinct cultivar of Argyranthemum plant named ‘SUN 440’, characterized by its uniformly mounded plant habit; freely branching habit; freely flowering habit; single-type inflorescences with white-colored ray florets; and good garden performance.

Description

Botanical designation: Argyranthemum frutescens.
Cultivar denomination: ‘SUN 440’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Argyranthemum plant, botanically known as Argyranthemum frutescens and hereinafter referred to by the cultivar name ‘SUN 440’.
The objective of the breeding program is to create new Argyranthemum plants with attractive ray and disc floret colors and good garden performance and pest resistance.
The new Argyranthemum plant originated from a cross-pollination made by the Inventor in August, 2011 in Glandorf, Germany of two unnamed seedling selections of Argyranthemum frutescens, not patented. The new Argyranthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Glandorf, Germany in July, 2012.
Asexual reproduction of the new Argyranthemum plant by vegetative tip cuttings was first conducted in Glandorf, Germany in February, 2013. 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 environmental conditions such as temperature, daylength 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 the new Argyranthemum plant. These characteristics in combination distinguish ‘SUN 440’ as a new and distinct Argyranthemum plant:
    • 1. Uniformly mounded plant habit.
    • 2. Freely branching habit.
    • 3. Freely flowering habit.
    • 4. Single-type inflorescences with white-colored ray florets.
    • 5. Good garden performance.
Plants of the new Argyranthemum differ from plants of the parent selections primarily in uniformity as plants of the new Argyranthemum are more uniformly mounding than plants of the parent selections.
Plants of the new Argyranthemum can be compared to plants of Argyranthemum frutescens ‘SUN 160’, not patented. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Argyranthemum differed primarily from plants of ‘SUN 160’ in ray floret color as plants of ‘SUN 160’ have red-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Argyranthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Argyranthemum plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘SUN 440’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘SUN 440’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the spring and early summer in 9-cm containers in a glass-covered greenhouse in Glandorf, Germany and under cultural practices typical of commercial potted Argyranthemum production. During the production of the plants, day temperatures ranged from 14° C. to 28° C., night temperatures ranged from 10° C. to 18° C. and light levels ranged from 25 klux to 90 klux. Plants were pinched one time five weeks after planting and were 2.5 months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
