Abstract

A new and distinct cultivar of Osteospermum plant named ‘Sunost1403’, characterized by its compact, upright, outwardly spreading and mounding plant habit; freely branching growth habit; freely flowering habit; large daisy-type inflorescences with purple violet and violet blue-colored ray florets; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.
Cultivar denomination: ‘SUNOST1403’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and hereinafter referred to by the name ‘Sunost1403’.
The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the program is to create and develop new Osteospermum plants with compact and uniformly mounded plant habit, freely flowering habit and attractive ray and disc floret coloration.
The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2011 of a proprietary selection of Osteospermum ecklonis identified as code number 09.20.003, not patented, as the female, or seed, parent with Osteospermum ecklonis ‘Sunost1101’, disclosed in U.S. Plant Pat. No. 24,162, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Odense, Denmark in June, 2012.
Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in Odense, Denmark since September, 2012 has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Osteospermum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunost1403’. These characteristics in combination distinguish ‘Sunost1403’ as a new and distinct Osteospermum plant:
    • 1. Compact, upright, outwardly spreading and mounding plant habit.
    • 2. Freely branching growth habit.
    • 3. Freely flowering habit.
    • 4. Large daisy-type inflorescences with purple violet and violet blue-colored ray florets.
    • 5. Good garden performance.
Plants of the new Osteospermum differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Osteospermum are more compact than plants of the female parent selection.
    • 2. Plants of the new Osteospermum and the female parent selection differ in ray floret color as plants of the female parent selection have pale purple-colored ray florets.
Plants of the new Osteospermum differ primarily from plants of the male parent, ‘Sunost1101’, in the following characteristics:
    • 1. Leaves of plants of the new Osteospermum are more undulate than leaves of plants of ‘Sunost1101’.
    • 2. Plants of the new Osteospermum and ‘Sunost1101’ differ in ray floret color as plants of ‘Sunost1101’ have purple-colored ray florets.
Plants of the new Osteospermum can be compared to plants of the Osteospermum ecklonis ‘Sunny Evita’, disclosed in U.S. Plant Pat. No. 16,667. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of ‘Sunny Evita’ in the following characteristics:
    • 1. Plants of the new Osteospermum had smaller and glossier leaves than plants of ‘Sunny Evita’.
    • 2. Plants of the new Osteospermum and ‘Sunny Evita’ differed in ray floret color as plants of ‘Sunny Evita’ had light purple-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Osteospermum plant 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 accurately describe the colors of the new Osteospermum plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Sunost1403’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Sunost1403’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown during the winter in 11-cm containers in a glass-covered greenhouse in Odense, Denmark and under cultural practices typical of commercial Osteospermum production. During the production of the plants, day temperatures ranged from 14° C. to 20° C. and night temperatures averaged 14° C. Plants were pinched one time and were 14 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
