Abstract

A new Argyranthemum plant particularly distinguished by its compact, rounded, growth habit, excellent branching, very early flowering, good heat tolerance, and large white flowers is disclosed.

Description

Genus and species: Argyranthemum frutescens.
Variety denomination: ‘Arg Whit’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of Argyranthemum, botanically known as Argyranthemum frutescens, and hereinafter referred to by the cultivar name ‘Arg Whit’. The new cultivar originated from a hybridization made in 2002 in Andijk, The Netherlands. The female parent is Argyranthemum ‘ARO-2-6-1’ an unpatented white Argyranthemum proprietary line, and the male parent is Argyranthemum ‘ARO-2-15-1’ an unpatented white Argyranthemum proprietary line.
The new cultivar was created in 2002 in Andijk, The Netherlands and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif., and Andijk, The Netherlands over a two-year period. The plant has also been trialed at Gilroy, Calif., Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Andijk, The Netherlands.
    • 1. A compact and rounded growth habit;
    • 2. Excellent branching;
    • 3. Very early flowering;
    • 4. Good heat tolerance; and
    • 5. Large, white flowers.
DESCRIPTION OF PHOTOGRAPH
This new Argyranthemum plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a 4½-month-old plant grown in an eight-inch pot in a poly-covered greenhouse with natural light in a late winter/spring trial setting.
The accompanying photograph shows blooms, buds, mature foliage, and plant habit; the inset shows mature inflorescences.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Arg Whit’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on eight-month-old plants grown in one-gallon pots in a poly-covered greenhouse. Color readings were taken in the greenhouse in the spring/summer season under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition). Texture description details were observed under a dissecting microscope.
