Abstract

A new and distinct cultivar of Osteospermum plant named ‘Sunost1103’, characterized by its compact, outwardly spreading and mounding plant habit; freely branching growth habit; freely flowering habit; large daisy-type inflorescences with purple-colored ray florets; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘SUNOST1103’.

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 ‘Sunost1103’.

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 inflorescence coloration.

The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2008 of a proprietary selection of Osteospermum ecklonis identified as code number 05.50.018, not patented, as the female, or seed, parent with Osteospermum ecklonis ‘Sunpix0804’, not patented, 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, 2009.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in Odense, Denmark since November, 2009, 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 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 ‘Sunost1103’. These characteristics in combination distinguish ‘Sunost1103’ as a new and distinct Osteospermum plant:

- 1. Compact, outwardly spreading and mounding plant habit.
- 2. Freely branching growth habit.
- 3. Freely flowering habit.
- 4. Large daisy-type inflorescences with purple-colored ray florets.
- 5. Good garden performance.

Plants of the new Osteospermum differ 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 are more freely branching than plants of the female parent selection.
- 3. Plants of the new Osteospermum have smaller leaves than plants of the female parent selection.
- 4. Plants of the new Osteospermum have lighter-colored ray florets than plants of ‘Sheila’.

Plants of the new Osteospermum differ from plants of the male parent, ‘Sunpix0804’, primarily in ray floret color as plants of ‘Sunpix0804’ have darker-colored ray florets. In addition, plants of the new Osteospermum are not as compact as plants of ‘Sunpix0804’.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Sunny Mary’, disclosed in U.S. Plant Pat. No. 16,389. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of ‘Sunny Mary’ in the following characteristics:

- 1. Plants of the new Osteospermum were more freely branching than plants of ‘Sunny Mary’.
- 2. Plants of the new Osteospermum had smaller leaves than plants of ‘Sunny Mary’.
- 3. Plants of the new Osteospermum and ‘Sunny Mary’ differed in ray floret color as plants of ‘Sunny Mary’ have darker-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 at the bottom of the sheet comprises a side perspective view of three typical flowering plants of ‘Sunost1103’ grown in a 21.5-cm container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Sunost1103’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown in Bonsall, Calif. during the summer in a polyethylene-covered greenhouse and under environmental conditions and cultural practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 18° C. to 32° C., night temperatures ranged from 7° C. to 18° C. and light levels ranged from 7,000 to 8,000 foot candles. Plants were pinched twice and were six 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.
