Abstract

A distinct cultivar of Osteospermum plant named ‘Aknam’, characterized by its uniformly mounded, outwardly spreading and compact plant habit; very freely branching growth habit; full and dense plants; freely flowering with numerous inflorescences per plant; spoon-shaped ray florets; and white-colored ray and disc florets.

Description

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 cultivar name Aknam.
The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Aabyhoj, Denmark. The objective of the breeding program is to create new Osteospermum cultivars with interesting ray floret colors and spoon-shaped ray florets.
The new Osteospermum originated from a cross made by the Inventor of an unidentified proprietary Osteospermum ecklonis seedling selection as the male, or pollen, parent with the proprietary Osteospermum ecklonis selection identified as code number 97008 as the female, or seed, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Aabyhoj, Denmark, in 1998.
Asexual reproduction of the new Osteospermum by vegetative tip cuttings was first conducted in Aabyhoj, Denmark in 1998. 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 Aknam has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, water status, and fertility levels without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Aknam’. These characteristics in combination distinguish ‘Aknam’ as a new and distinct Osteospermum:
1. Uniformly mounded, outwardly spreading and compact plant habit.
2. Very freely branching growth habit; full and dense plants.
3. Freely flowering with numerous inflorescences per plant.
4. Spoon-shaped ray florets.
5. White-colored ray and disc florets.
Compared to plants of the parent selections, plants of the new Osteospermum are more compact and differ in ray floret coloration.
The new Osteospermum can be compared to the Osteospermum ecklonis culltivar Aksillo, disclosed in U.S. Plant Pat. application Ser. No. 09/422,169. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Osteospermum differ from plants of the cultivar Aksillo in the following characteristics:
1. Plants of the new Osteospermum have slightly larger inflorescences, more ray florets, larger discs and more disc florets than plants of the culitvar Aksillo.
2. The upper surface of the ray florets of plants of the new Osteospermum is not as pure white in color as the upper surface of ray florets of plants of the cultivar Aksillo.
3. The lower surface of the ray florets of plants of the new Osteospermum is white and pale yellow in color whereas the lower surface of ray florets of plants of the cultivar Aksillo is blue purple.
4. Disc florets of plants of the new Osteospermum are white in color whereas disc florets of plants of the cultivar Aksillo are blue purple.
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. Colores 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 ‘Aknam’.
The photograph at the bottom of the sheet is a close-up view of typical leaves, inflorescences and flower buds of ‘Aknam’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown and flowered during the spring in Encinitas, Calif., under outdoor conditions which approximate those generally used in commercial production. One rooted cutting was planted in a 20-cm container and pinched once. Measurements and numerical values represent averages of typical flowering plants about 22 weeks after planting.
