Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘Sumost 05’.

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 ‘Sumost 05’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Lüdinghausen, Germany. The objective of the program is to create and develop new compact Osteospermum cultivars with attractive and unique inflorescence coloration.

The new Osteospermum originated from a cross-pollination by the Inventor in February, 2002 of a proprietary selection of Osteospermum ecklonis identified as code number XY4, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number 01-5, 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 environment in Lüdinghausen, Germany in May, 2003.

Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled environment in Lüdinghausen, Germany since June, 2003, 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 cultivar Sumost 05 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.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sumost 05’. These characteristics in combination distinguish ‘Sumost 05’ as a new and distinct cultivar of Osteospermum:

    • 1. Compact, upright and outwardly spreading plant habit.
    • 2. Freely branching growth habit.
    • 3. Freely and continuous flowering habit.
    • 4. Daisy-type inflorescences with orange-colored ray florets with violet-colored bases.

In side-by-side comparisons conducted in Lüdinghausen, Germany, 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 freely flowering than plants of the female parent selection.
    • 2. Plants of the new Osteospermum have smaller inflorescences than plants of the female parent selection.
    • 3. Plants of the new Osteospermum and the female parent selection differ in ray floret coloration as plants of the female parent selection have soft orange-colored ray florets.

In side-by-side comparisons conducted in Lüdinghausen, Germany, plants of the new Osteospermum differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Osteospermum are more compact than plants of the male parent selection.
    • 2. Plants of the new Osteospermum and the male parent selection differ in ray floret coloration as plants of the male parent selection have lighter orange-colored ray florets.

Plants of the new Osteospermum can be compared to plants of the Osteospermum cultivar Sumost 02, disclosed in U.S. Plant Pat. No. 15,975. In side-by-side comparisons conducted in Lüdinghausen, Germany, plants of the new Osteospermum differed from plants of the cultivar Sumost 02 in the following characteristics:

    • 1. Plants of the new Osteospermum were more compact than plants of the cultivar Sumost 02.
    • 2. Plants of the new Osteospermum had shorter internodes than plants of the cultivar Sumost 02.
    • 3. Plants of the new Osteospermum had smaller inflorescences than plants of the cultivar Sumost 02.
    • 4. Plants of the new Osteospermum and the cultivar Sumost 02 differed in ray floret coloration as plants of the cultivar Sumost 02 had soft orange-colored ray florets.
    • 5. Plants of the new Osteospermum did not produce seeds whereas plants of the cultivar Sumost 02 produced seeds.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Osteospermum. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum. The photograph comprises a top perspective view of a typical flowering plant of ‘Sumost 05’.

 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 photograph, following observations and measurements describe plants grown 10.5-cm containers in Lüdinghausen, Germany during the summer and autumn 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 18° C. to 22° C., night averaged 16° C. and light levels ranged from 3,000 to 6,000 kilolux. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were about four months old when the photograph and description were taken.
