Abstract

A distinct cultivar of Osteospermum plant named ‘Vanilla Cream’, characterized by its compact, mounding and outwardly spreading growth habit; dark green leaves; freely branching habit; ivory-colored ray florets; numerous inflorescences per lateral stem; long flowering period; and relative tolerance to high temperatures.

Description

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osterspermum ecklonis, and referred to by the cultivar name Vanilla Cream.
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 inflorescences and tolerance to high temperatures.
The new cultivar originated from a cross made by the Inventor of a proprietary selection of Osteospermum ecklonis identified as code number ivory 41 as the female, or seed, parent and a proprietary selection of Osteospermum ecklonis identified as code number ivory 96, 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 1994.
Plants of the new cultivar are different from plants of the female parent, the selection ivory 41 in plant habit and inflorescence size. Plants of the new Osteospermum are less trailing and have more rounded ray florets than plants of the male parent, the selection ivory 96.
Asexual propagation of the new cultivar by terminal cuttings at Emerald, Victoria, Australia, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.
SUMMERY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Vanilla Cream’. These characteristics in combination distinguish ‘Vanilla Cream’ as a new and distinct cultivar:
1. Compact, mounding and outwardly spreading growth habit.
2. Dark green leaves.
3. Freely branching habit.
4. Ivory-colored ray florets.
5. Numerous inflorescences per lateral stem.
6. Long flowering period.
7. Relatively tolerant to high temperatures.
The new cultivar can be compared to the Osteospermum cultivar Cream Symphony, not patented. However in side-by-side comparisons conducted in Emerald, Victoria, Australia, plants of the new cultivar are more outwardly spreading, are larger and stronger, have ray florets with yellow-striped lower surfaces and have more florets per inflorescence than plants of the cultivar Cream Symphony.
The cultivar Vanilla Cream 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. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Osteospermum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Vanilla Cream’.
The photograph at the bottom of the sheet is a close-up view of an inflorescence bud, lower surface of typical ray florets, typical inflorescence and upper and lower surfaces of typical leaves of ‘Vanilla Cream’. The age and the environmental conditions of the plant depicted in the photograph are the same as those described in the Detailed Botanical Description.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe 20-cm containers with three 10 week old plants of the new cultivar grown in Bonsall, Calif., under outdoor, full-sun conditions with dry temperatures ranging from 21 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.
