Abstract

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

Description

Botanical classification/cultivar designation: Osteospermum ecklonis cultivar Sevamil.
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 ‘Sevamil’.
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 June, 2000, as a single flowering plant within a population of plants of the parent cultivar in a controlled environment in Sondersoe, Denmark.
Asexual reproduction of the new Osteospermum by terminal vegetative cuttings was first conducted in Sondersoe, Denmark in August, 2000. 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 Sevamil 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 ‘Sevamil’. These characteristics in combination distinguish ‘Sevamil’ as a new and distinct Osteospermum:
1. Compact, mounded and outwardly spreading plant habit.
2. Freely branching growth habit.
3. Freely flowering habit.
4. Pale yellow-colored ray florets and dark purple-tipped disc florets.
Plants of the new Osteospermum are most similar to plants of the parent, the cultivar Seikilrem. Plants of the new Osteospermum differ primarily from plants of the cultivar Seikilrem in ray floret coloration as plants of the cultivar Seikilrem have bright yellow-colored ray florets.
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 a typical flowering plant of ‘Sevamil’ grown in a 15-cm container.
The photograph at the bottom of the sheet is a close-up view of typical inflorescences, inflorescence buds and leaves of ‘Sevamil’.
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 7 to 18° C. After planting rooted cuttings, plants were grown for about six weeks in 15-cm containers. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
