| Abstract: |
A new and distinct cultivar of Osteospermum plant named `Sunny Serena`, characterized by its compact, upright and mounded plant habit; dense and bushy growth habit; freely flowering habit; and pale yellow-colored ray florets and gray-colored disc florets. |
| Claim: |
It is claimed:
1. A new and distinct cultivar of Osteospermum plant named `Sunny Serena`, as illustrated and described. |
| Description: |
Botanicalclassification/cultivar designation: Osteospermum ecklonis cultivar Sunny Serena.
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 Serena`.
The new Osteospermum 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 longevityand attractive flower coloration.
The new Osteospermum originated from a cross-pollination made by the Inventor in May, 1998 of the Osteospermum ecklonis cultivar Sunny Alex, not patented, as the female, or seed, parent with the Osteospermum ecklonis cultivar Sunny Martha,disclosed in U.S. Plant Pat. No. 10,978, as the male, or pollen, parent.
The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the resulting progeny from the cross-pollination in a controlled environment in Odense, Denmark in June, 2000.
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 totype in successive generations.
SUMMARY OF THE INVENTION
The cultivar Sunny Serena 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 ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sunny Serena`. These characteristics in combination distinguish `Sunny Serena` as a new and distinct Osteospermum: 1. Compact, uprightand mounded plant habit. 2. Dense and bushy growth habit. 3. Freely flowering habit. 4. Pale yellow-colored ray florets and gray-colored disc florets.
Plants of the new Osteospermum are most similar to plants of the parents, the cultivars Sunny Alex and Sunny Martha. Plants of the new Osteospermum differ primarily from plants of the cultivars Sunny Alex and Sunny Martha, in ray floretcoloration as ray florets of plants of the cultivars Sunny Alex and Sunny Martha are yellow and purple in color, respectively.
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 thecolor 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 Serena` grown in a container.
The photograph on the second sheet is a top perspective view of a typical flowering plant of `Sunny Serena` grown in a container.
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 in11-cm containers. During the first five weeks of production of the plants, day and night temperature were about 20.degree. C., then temperatures were reduced to 14.degree. C. Color references are made to The Royal Horticultural Society Colour Chart,4.sup.th Edition, except where general terms of ordinary dictionary significance are used.
