Description

Botanical classification/cultivar designation: Osteospermum ecklonis cultivar Sunny Flora.

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 ‘Sunny Flora’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the breeding program is to create new compact Osteospermums with continuous flowering, good postproduction longevity and attractive flower coloration.

The new Osteospermum originated from a self-pollination made by the Inventor in 2001 of the Osteospermum ecklonis cultivar Sunny Alex, not patented.

The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the resulting progeny from the self-pollination in a controlled environment in Odense, Denmark.

Asexual reproduction of the new Osteospermum by terminal vegetative cuttings was first conducted in Odense, Denmark. Asexual reproduction by cuttings 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 Sunny Flora 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 ‘Sunny Flora’. These characteristics in combination distinguish ‘Sunny Flora’ as a new and distinct Osteospermum:

1. Compact, upright and mounded plant habit.

2. Dense and bushy growth habit.

3. Freely flowering habit.

4. Large inflorescences.

5. Red purple-colored ray florets and dark purple-tipped disc florets.

Compared to plants of the parent, the cultivar Sunny Alex, plants of the new Osteospermum are more compact, have lighter green-colored leaves, and have shorter and stronger peduncles.

Plants of the new Osteospermum can be compared to plants of the cultivar Sunny Lady, disclosed in U.S. Plant Pat. No. 10,353. In side-by-side comparisons conducted in Fyn, Denmark, plants of the new Osteospermum differed from plants of the cultivar Sunny Lady in the following characteristics:

1. Plants of the new Osteospermum were more compact and denser than plants of the cultivar Sunny Lady.

2. Plants of the new Osteospermum were more upright and not as outwardly spreading as plants of the cultivar Sunny Lady.

3. Plants of the new Osteospermum had lighter green-colored foliage than plants of the cultivar Sunny Lady.

4. Plants of the new Osteospermum and the cultivar Sunny Lady differed in ray floret coloration as plants of the cultivar Sunny Lady had lighter-colored ray florets.

5. Plants of the new Osteospermum had longer and sturdier peduncles than plants of the cultivar Sunny Lady.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Osteospermum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Sunny Flora’ grown in a 11-cm container.

The photograph on the second sheet is a top perspective view of a typical flowering plant of ‘Sunny Flora’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Fyn, Denmark, in a glass-covered greenhouse during the winter and spring. After planting rooted cuttings, plants were grown for about 20 weeks in 11-cm containers. During the first five weeks of production of the plants, day and night temperatures were about 20° C., then temperatures were reduced to 14° C. Color references were made to The Royal Horticultural Society Colour Chart, 4th Edition, except where general terms of ordinary dictionary significance are used.
