Abstract

A new and distinct cultivar of Osteospermum plant named ‘Sunost0802’, characterized by its compact and mounded plant habit; freely branching growth habit; freely flowering habit; large daisy-type inflorescences with red-colored ray florets; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘Sunost0802’.

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 ‘Sunost0802’.

The new Osteospermum 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 cultivars with compact and uniformly mounded plant habit, freely flowering habit and attractive inflorescence coloration.

The new Osteospermum originated from a cross-pollination by the Inventor in May, 2006 of Osteospermum ecklonis ‘Sheila’, disclosed in U.S. Plant Pat. No. 18,066, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code No. 03.70.003, not patented, as the male, or pollen, parent. The new Osteospermum 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 May, 2006.

Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled greenhouse environment in Odense, Denmark since November, 2007, has shown that the unique features of this new Osteospermum 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. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Sunost0802’. These characteristics in combination distinguish ‘Sunost0802’ as a new and distinct cultivar of Osteospermum:

• • 1. Compact and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Large daisy-type inflorescences with red-colored ray florets.
  • 5. Good garden performance.

Plants of the new Osteospermum differ from plants of the female parent, ‘Sheila’, in the following characteristics:

• • 1. Plants of the new Osteospermum are more freely branching than plants of ‘Sheila’.
  • 2. Plants of the new Osteospermum have larger leaves than plants of ‘Sheila’.

Plants of the new Osteospermum differ from plants of the male parent selection primarily in ray floret color as plants of the male parent selection have paler red-colored ray florets. In addition, plants of the new Osteospermum are more upright than plants of the male parent selection.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Sunny Fiona’, disclosed in U.S. Plant patent application Ser. No. 11/821,112. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of ‘Sunny Fiona’ in the following characteristics:

• • 1. Plants of the new Osteospermum were more freely branching than plants of ‘Sunny Fiona’.
  • 2. Plants of the new Osteospermum and ‘Sunny Fiona’ differed in ray floret color as plants of ‘Sunny Fiona’ have pink-colored ray florets.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Sunost0802’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in Odense, Denmark during the spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 14° C. to 20° C., night temperatures averaged 14° C. and light levels ranged from 200 to 800 watts per square meter. Plants were pinched one time. Plants had been growing for 15 weeks when the photographs and description were taken.
