plant named ‘J0208-1’

Abstract

A new Argyranthemum plant named ‘J0208-1’ particularly distinguished by its vigorous round plant habit with dark green foliage, and its early, rich and long flowering with white flowers with a dark red center.

Description

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

Varietal denomination: ‘J0208-1’.

BACKGROUND OF THE NEW PLANT

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 ‘J0208-1.’ The new cultivar is a product of a planned breeding program conducted in Enkhuizen, Netherlands.

The new Argyranthemum originated from an open pollination conducted in a controlled environment in Enkhuizen, Netherlands in 2004 of a proprietary selection of Argyranthemum frutescens identified as code number ‘B0050-1,’ not patented, as the female, or seed, parent with pollen of unknown Argyranthemum fruiescens plants as the male, or pollen, parent.

The cultivar ‘J0208-1’ was discovered and selected as a single plant within the progeny of the stated open pollination in Enkhuizen, Netherlands, in August 2005. The new Argyranthemum has been repeatedly asexually reproduced in Enkhuizen, Netherlands since August 2005. The distinctive characteristics 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 ‘J0208-1’ and distinguish to new Argyranthemum as a new and distinct cultivar:

• • 1. Round plant habit.
  • 2. Early flowering habit.
  • 3. Freely flowering habit with numerous inflorescences per plant.
  • 4. Dark green foliage.
  • 5. Strong vigor.
  • 6. White flowers with a dark red centre.

Plants of the new Argyranthemum differ from plants of the female parent in the following characteristics:

‘J0208-1’ has flowers with a dark red center while the female parent has flowers with a greenish-yellowish center.

‘J0208-1’ has a round plant habit while the female parent has a more upright plant type.

‘J0208-1’ has rather long peduncles while the female parent has very short peduncles.

Differences between plants of the new Argyranthemum and plants of the male parent are unknown, as the male parent is unknown.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photograph illustrates 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, Netherlands. The plant history was taken on plants of 15 weeks old, grown in the open field in Enkhuizen, Netherlands, with day temperatures ranging from 16 to 35° C., and night temperatures ranging from 10 to 20° C.

Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society, 2001 Edition, except where general terms of ordinary dictionary significance are used.
