Abstract

A distinct cultivar of Marguerite daisy plant named `Sugar Baby`, characterized by its compact plant habit; dense, bushy and freely branching plant form; freely and early flowering; and pure white ray and bright yellow disc florets.

Description

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 `Sugar Baby`.
The new cultivar is a product of a planned breeding program conducted by the inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program was to develop compact and freely-flowering Marguerite daisies that flower early.
The new cultivar originated from a cross made by the inventor in 1991 of a seedling selection of Argyranthemum frutescens identified as number 90003, as the male or pollen parent, with the Argyranthemum frutescens cultivar `Frosty` (not patented), as the female or seed parent. The cultivar `Sugar Baby` was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Cobbitty, New South Wales, Australia. Plants of the new Marguerite daisy are more compact than either of its parents.
Asexual reproduction of the new cultivar by terminal cuttings taken in Cobbitty, New South Wales, Australia, and Encinitas, Calif., has shown that the unique features of this new Marguerite daisy are stable and are reproduced true to type in successive propagations.
The new cultivar 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 `Sugar Baby` which distinguish `Sugar Baby` as a new and distinct cultivar:
1. Compact plant habit.
2. Dense, bushy and freely branching plant form.
3. Numerous inflorescences per plant.
4. Early flowering.
5. Pure white ray and bright yellow disc florets.
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 first photograph comprises a side perspective view of a typical container plant of `Sugar Baby`.
The second photograph comprises a close-up view of inflorescences of plants of `Sugar Baby`. Floret and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
The following observations, measurements, values, and comparisons describe plants grown in Encinitas, Calif., under outdoor conditions. Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
