Abstract

A distinct cultivar of Marguerite Daisy plant named Midas Gold, characterized by its rounded, outwardly spreading and mounding plant habit; freely branching, dense and bushy plants; very narrow, deeply divided, lacy, fern-like leaves; freely flowering with numerous inflorescences per plant held beyond the foliage; large single-type inflorescences; yellow ray florets and distinct brownish red-tipped immature disc florets which give an “bull's eye” appearance to the inflorescence; and high temperature and humidity tolerance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as Argyranthemum frutescens and referred to by the cultivar name Midas Gold.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Emerald, Victoria, Australia.
The new cultivar originated from a cross made by the Inventor in 1994 of an unidentified selection of Argyranthemum frutescens, as the male or pollen parent, with an unidentified selection of Argyranthemum frutescens as the female or seed parent. The cultivar Midas Gold was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Emerald, Victoria, Australia.
Asexual propagation of the new cultivar by terminal cuttings in Emerald, Victoria, Australia, has shown that the unique features of this new Marguerite Daisy are stable and are reproduced true to type in successive propagations.
SUMMARY OF THE INVENTION
The new Marguerite Daisy has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Midas Gold’ which distinguish ‘Midas Gold’ as a new and distinct cultivar:
1. Rounded, outwardly spreading and mounding plant habit; vigorous; freely branching, dense and bushy plants.
2. Very narrow, deeply divided, lacy, fern-like leaves.
3. Freely flowering with numerous inflorescences per plant held beyond the foliage.
4. Large single-type inflorescences.
5. Yellow ray florets and distinct brownish red-tipped immature disc florets which give an “bull's eye” appearance to the inflorescence.
6. High temperature and humidity tolerance.
Plants of the new Marguerite Daisy can be compared to plants of the cultivar Lemon Delight (U.S. Plant patent application Ser. No. 09/263,150). In side-by-side comparisons conducted in Emerald, Victoria, Australia, plants of the new Marguerite Daisy are different from plants of the cultivar Lemon Delight in ray and disc floret color and leaf shape.
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.
The photograph at the top of the sheet comprises a top perspective view of two typical plants of ‘Midas Gold’ in a 25-cm container.
The photograph at the bottom of the sheet comprises close-up views of developing inflorescences (top) and mature and young leaves (bottom). Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe a 25-cm container of two plants of the new Marguerite Daisy grown in Bonsall, Calif., in full sun with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 13 to 18° C.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
