Argyranthemum plant named ‘Supa0186’

Abstract

A new and distinct cultivar of Argyranthemum plant named ‘Supa0186’, characterized by its compact, upright and mounded plant habit; freely branching habit, dense and bushy plants; freely flowering habit with numerous inflorescences per plant; anemone-type inflorescence form with light purple-colored ray florets and red purple-tipped disc florets.

Description

Botanical classification/cultivar denomination: Argyranthemum frutescens cultivar Supa0186.

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 ‘Supa0186’.

The new Argyranthemum is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the program is to create and develop new compact Argyranthemum cultivars with numerous inflorescences, interesting inflorescence form and attractive ray floret coloration.

The new Argyranthemum originated from a cross-pollination by the Inventor in July, 1998, of a proprietary selection of Argyranthemum frutescens identified as code number DMsel.24, not patented, as the female, or seed, parent, with a proprietary selection of Argyranthemum frutescens identified as code number PS169, not patented, as the male, or pollen, parent. The new Argyranthemum was discovered and selected by the Inventor as a plant within the progeny of the stated cross-pollination in a controllled environment in Cobbitty, New South Wales, Australia in October, 2000. The selection of the new Argyranthemum was based on its attractive inflorescence form and ray floret coloration.

Asexual reproduction of the new Argyranthemum by terminal cuttings in a controlled environment in Cobbitty, New South Wales, Australia since October, 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 ‘Supa0186’ and distinguish the new Argyranthemum as a new and disctinct cultivar:

• • 1. Compact, upright and mounded plant habit.
  • 2. Freely branching habit, dense and bushy plants.
  • 3. Freely flowering habit with numerous inflorescences per plant.
  • 4. Anemone inflorescence form with light purple-colored ray florets and red purple-tipped disc florets.

Plants of the new Argyranthemum differ from plants of the female parent selection primarily in floret coloration as plants of the female parent selection have pink-colored ray and disc florets. Plants of the new Argyranthemum differ from plants of the male parent selection primarily in inflorescence form as plants of the male parent selection have daisy-type inflorescences. In addition, plants of the new Argyranthemum are not as compact as plants of the male parent selection.

Plants of the new Argyranthemum can be compared to plants of the cultivar Supacrest, disclosed in U.S. Plant patent application Ser. No. 10/862,858. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Argyranthemum differed primarily from plants of the cultivar Supacrest in floret coloration as plants of the cultivar Supacrest had purple-colored ray florets and yellow-colored disc florets. In addition, plants of the new Argyranthemum had smaller inflorescences than plants of the cultivar Supacrest.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Argyranthemum.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Supa0186’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical inflorescences of ‘Supa0186’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and averaged measurements describe plants grown in Encinitas, Calif., in an outdoor nursery under full sunlight during the winter and spring with day temperatures ranging from 15 to 24° C. and night temperatures ranging from 10 to 19° C. Plants were grown in one-gallon containers with one plant per container. Plants were pinched one time about five weeks after planting. Plants had been growing for about 15 weeks when the photographs and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
