Abstract

A distinct cultivar of Osteospermum plant named ‘White Moon’, characterized by its upright, mounding and outwardly spreading growth habit; small numerous leaves and large upright inflorescences on long peduncles; vigor; freely branching habit; white-colored ray florets contrasted by dark bluish purple-tipped disc florets and bluish base of ray florets; and numerous inflorescences per plant.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and referred to by the cultivar name ‘White Moon’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Emerald, Victoria, Australia. The objective of the breeding program was to create new compact Osteospermum cultivars with large flowers.
The new cultivar originated from a cross made by the Inventor in 1993 of a proprietary selection of Osteospermum ecklonis identified as 90/75 as the female, or seed, parent and the Osteospermum ecklonis cultivar Sparkler II, not patented, as the male, or pollen, parent. The new Osteospermum was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Emerald, Victoria, Australia in 1993.
Plants of the new cultivar are different from plants of the female parent, the selection 90/75 in leaf shape, peduncle length and inflorescence size. Plants of the new Osteospermum are more compact than plants of the male parent, the cultivar Sparkler II.
Asexual propagation of the new cultivar by terminal cuttings and by tissue culture at Emerald, Victoria, Australia, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘White Moon’. These characteristics in combination distinguish ‘White Moon’ as a new and distinct cultivar:
1. Upright, mounding and outwardly spreading growth habit.
2. Small numerous leaves and large upright inflorescences on long peduncles.
3. Vigorous and freely branching.
4. White-colored ray florets contrasted by dark bluish purple-tipped disc florets and bluish base of ray florets.
5. Numerous inflorescences per plant.
The new cultivar can be compared to the Osteospermum cultivar Sparkler, not patented. However in side-by-side comparisons conducted in Emerald, Victoria, Australia, plants of the new cultivar are more compact and differ in leaf shape, inflorescence size and peduncle length.
The cultivar ‘White Moon’ 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.
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 a typical flowering plant of ‘White Moon’.
The photograph at the bottom of the sheet is a close-up view of lower and upper surfaces of typical inflorescences (top) and upper and lower surfaces of typical leaves (bottom) of ‘White Moon’. Foliage and floret 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 an one-gallon container with three plants of the new cultivar grown in Bonsall, Calif., under outdoor, full-sun conditions 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.
