Abstract

A new and distinct cultivar of Osteospermum plant named ‘Aknai’, characterized by its uniformly mounded plant habit; freely branching growth habit; full and dense plants; freely flowering habit; dark green-colored foliage; inflorescences with white-colored ray florets; and high temperature tolerance.

Description

Botanical classification/cultivar designation: Osteospermum ecklonis cultivar Aknai.
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 ‘Aknai’.
The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Aabyhøj, Denmark. The objective of the breeding program is to create new Osteospermum cultivars with uniform plant habit, interesting floret colors and high temperature tolerance.
The new Osteospermum originated from a cross-pollination made by the Inventor during the spring of 1999 of the Osteospermum ecklonis cultivar Akkali, not patented, as the female, or seed, parent with the Osteospermum ecklonis cultivar Brightside, disclosed in U.S. Plant Pat. No. 10,596, as the male, or pollen, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Aabyhøj, Denmark during the spring of 2000.
Asexual reproduction of the new Osteospermum by vegetative tip cuttings was first conducted in Aabyhøj, Denmark in February, 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 Aknai has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘Aknai’. These characteristics in combination distinguish ‘Aknai’ as a new and distinct Osteospermum:
    • 1. Uniformly mounded plant habit.
    • 2. Freely branching growth habit; full and dense plants.
    • 3. Freely flowering habit.
    • 4. Dark green-colored foliage.
    • 5. Inflorescences with white-colored ray florets.
    • 6. Tolerant to high temperatures.
In side-by side comparisons conducted in Aabyhøj, Denmark, plants of the new Osteospermum differed from plants of the female parent, the cultivar Akkali, in the following characteristics:
    • 1. Plants of the new Osteospermum were more upright and mounded than plants of the cultivar Akkali.
    • 2. Plants of the new Osteospermum had broader leaves than plants of the cultivar Akkali.
In side-by-side comparisons conducted in Aabyhøj, Denmark, plants of the new Osteospermum differed from plants of the male parent, the cultivar Brightside, in the following characteristics:
    • 1. Plants of the new Osteospermum more were compact than plants of the cultivar Brightside.
    • 2. Plants of the new Osteospermum were more freely flowering than plants of the cultivar Brightside.
    • 3. Plants of the new Osteospermum were stronger and healthier than plants of the Brightside.
Plants of the new Osteospermum can be compared to plants of the cultivar Nairobi, not patented. In side-by-side comparisons conducted in Aabyhøj, Denmark, plants of the new Osteospermum differed from plants of the cultivar Nairobi, in the following characteristics:
    • 1. Plants of the new Osteospermum were more freely branching than plants of the cultivar Nairobi.
    • 2. Plants of the new Osteospermum had shorter peduncles than plants of the cultivar Nairobi.
    • 3. Plants of the new Osteospermum were more high temperature-tolerant than plants of the cultivar Nairobi.
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 ‘Aknai’ grown in container.
The photograph at the bottom of the sheet is a close-up view of typical leaves and inflorescences of ‘Aknai’.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
The aforementioned photographs, following observations and measurements describe plants grown during the late winter and early spring in Encinitas, Calif., in a polyethylene-covered greenhouse and under conditions which approximate those generally used in commercial Osteospermum production. Single plants were grown in one-gallon containers and pinched once. During the production of the plants, day temperatures were about 24° C., night temperatures were about 19° C., and light levels were about 4,000 foot-candles. Measurements and numerical values represent averages of typical flowering plants about 20 weeks after planting.
