Abstract

A new and distinct cultivar of Osteospermum plant named ‘Sekiin47’, characterized by its compact, mounded and outwardly spreading plant habit; freely branching habit; freely flowering habit; and intense yellow-colored ray florets with dark violet blue towards the base and dark purple-tipped disc florets.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related application entitled Osteospermum Plant Named ‘Seipepan’; Jorn Hansson, applicant.

Botanical classification/cultivar designation: Osteospermum ecklonis cultivar Sekiin47.

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 ‘Sekiin47’.

The new Osteospermum was discovered as a naturally-occurring whole plant mutation of the Osteospermum ecklonis cultivar Seikilrem, disclosed in U.S. Plant Pat. No. 13,407.

The new Osteospermum was discovered and selected by the Inventor in May, 2001, as a single flowering plant within a population of plants of the parent cultivar in a controlled environment in Germany.

Asexual reproduction of the new Osteospermum by terminal vegetative cuttings was first conducted in Sondersoe, Denmark in August, 2001. 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 Sekiin47 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 ‘Sekiin47’. These characteristics in combination distinguish ‘Sekiin47’ as a new and distinct Osteospermum:

- 1. Compact, mounded and outwardly spreading plant habit.
- 2. Freely branching habit.
- 3. Freely flowering habit.
- 4. Intense yellow-colored ray florets with dark violet blue towards the base and dark purple-tipped disc florets.

Plants of the new Osteospermum differ primarily from plants of the parent, the cultivar Seikilrem, in ray floret coloration.

Plants of the new Osteospermum differ primarily from plants of the cultivar Seipepan, disclosed in a U.S. Plant patent application Ser. No. 10/949,950 filed concurrently, in ray floret coloration.

Plants of the new Osteospermum are similar in ray floret coloration to plants of the cultivar Cape Daisy Zulu, disclosed in U.S. Plant Pat. No. 10,389. However, plants of the new Osteospermum are more outwardly spreading and more freely flowering than plants of the cultivar Cape Daisy Zulu.

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 at the top of the sheet is a close-up view of a typical inflorescence of ‘Sekiin47’.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Sekiin47’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in a polyethylene-covered greenhouse during the winter and under conditions typical of commercial Osteospermum production. During the production of the plants day temperatures ranged from 13 to 32° C. and night temperatures ranged from 10 to 16° C. Plants had been growing for about ten weeks in 15.25-cm containers when the photographs and the description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used.
