USPP19856P2 - Argyranthemum frutescens plant named ‘Argylem’ - Google Patents

Abstract

A new and distinct cultivar of Argyranthemum frustescens plant named ‘Argylem’ characterized by its compact and dense plant habit with short internodes and dark green foliage, and its early, rich and long flowering with lemon semi double anemone-like flowers.

Description

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

Varietal denomination: ‘Argylem’.

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 ‘Argylem.’

The new cultivar is a product of a planned breeding program conducted in Enkhuizen, Netherlands. The new cultivar ‘Argylem’ is characterized by its special flower shape, very floriferous habit and very compact plant habit with good branching.

The new Argyranthemum originates from an open pollination conducted in Enkhuizen, Netherlands in 2003 of the Argyranthemum frutescens variety ‘Argypri’ (U.S. Ser. No. 12/011,531) as the female, or seed, parent with pollen of unknown Argyranthemum frutescens plants as the male, or pollen, parent.

The cultivar ‘Argylem’ was discovered and selected as a single plant within the progeny of the stated open pollination in a controlled environment in Enkhuizen, Netherlands in August 2004. Asexual reproduction of the new Argyranthemum by terminal cuttings in a controlled environment in Enkhuizen, Netherlands since August 2004, 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 ‘Argylem’ and distinguish to new Argyranthemum as a new and distinct cultivar:

• • 1. Compact 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. Dark green foliage
  • 6. Semi double anemone-like flowers

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

• • 1. Plants of the new Argyranthemum have a height of 20 cm, whereas plants of the female parent have a height of 40 cm.
  • 2. Plants of the new Argyranthemum have a width of 34 cm, whereas plants of the female parent have a width of 65 cm.
  • 3. Plants of the new Argyranthemum have a flower diameter of 3.5-4 cm, whereas plants of the female parent have a flower diameter of 5-6 cm.

The difference of plants of the new Argyranthemum from plants of the male parent is unknown, as the male parent is unknown.

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

BOTANICAL DESCRIPTION OF THE PLANT

The aforementioned photographs, the 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 20 week old plants, 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 R.H.S. Colour Chart of The Royal Horticultural Society, 1995 Edition, except where general terms of ordinary dictionary significance are used.
