Abstract

A distinct cultivar of Osteospermum plant named ‘Seikilrem’, characterized by its uniformly mounded and outwardly spreading plant habit; freely branching growth habit; freely flowering habit; and bright yellow-colored ray florets and dark purple-tipped disc florets.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Osteospermum ecklonis cultivar Seikilrem.
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 ‘Seikilrem’.
The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Gunma-den, Japan. The objective of the breeding program is to create new Osteospermum cultivars with interesting floret colors.
The new Osteospermum was discovered as a naturally-occurring whole plant mutation of the Osteospermum ecklonis cultivar Seidacre, U.S. Plant patent application filed concurrently, Ser. No. 09/996,362.
The new Osteospermum was discovered and selected by the Inventor in April, 1993, as a single flowering plant within a population of plants of the parent cultivar in a controlled environment in Gunma-den, Japan.
Asexual reproduction of the new Osteospermum by terminal vegetative cuttings was first conducted in Gunma-den, Japan on Jun. 1, 1993. 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 Seikilrem 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 ‘Seikilrem’. These characteristics in combination distinguish ‘Seikilrem’ as a new and distinct Osteospermum:
1. Compact, mounded and outwardly spreading plant habit.
2. Freely branching growth habit.
3. Freely flowering habit.
4. Bright yellow-colored ray florets and dark purple-tipped disc florets.
Plants of the new Osteospermum differ primarily from plants of the parent, the cultivar Seidacre, 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 comprises a side perspective view of three typical flowering plants of ‘Seikilrem’ grown in a 22-cm container.
The photograph at the bottom of the sheet is a close-up view of typical developing inflorescence buds, upper and lower surfaces of typical fully opened inflorescences, and upper surfaces of typical leaves of ‘Seikilrem’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the late spring and early summer under full sun conditions with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 4 to 18° C. After planting rooted cuttings, plants were grown for about eight weeks in 22-cm containers with three plants per container and were pinched one time. Color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used.
