plant named ‘Fidostnanowhi’

Abstract

A new and distinct cultivar of Osteospermum plant named ‘Fidostnanowhi’, characterized by its compact and mounding plant habit; freely branching growth habit; early and freely flowering habit; daisy-type inflorescences with white-colored ray florets; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘FIDOSTNANOWHI’.

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 ‘Fidostnanowhi’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the program is to create and develop new compact Osteospermum plants that are freely branching, early and freely flowering and have attractive inflorescence coloration.

The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2006 of a proprietary selection of Osteospermum ecklonis identified as code number O 45706, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number O 67237, not patented, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands in October, 2006.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since Nov. 1, 2006, has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Osteospermum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Fidostnanowhi’. These characteristics in combination distinguish ‘Fidostnanowhi’ as a new and distinct Osteospermum plant:

• • 1. Compact and mounding plant habit.
  • 2. Freely branching growth habit.
  • 3. Early and freely flowering habit.
  • 4. Daisy-type inflorescences with white-colored ray florets.
  • 5. Good garden performance.

Plants of the new Osteospermum differ from plants of the female parent selection primarily in leaf orientation as plants of the new Osteospermum flower have flat leaves whereas plants of the female parent selection have curly leaves.

Plants of the new Osteospermum differ from plants of the male parent selection primarily in branch diameter as plants of the new Osteospermum have thicker lateral branches than plants of the male parent selection.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Fidostwhi’, disclosed in U.S. Plant Pat. No. 20,548. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Osteospermum differed primarily from plants of ‘Fidostwhi’ in the following characteristics:

• • 1. Plants of the new Osteospermum were more compact than plants of ‘Fidostwhi’.
  • 2. Plants of the new Osteospermum flowered earlier than plants of ‘Fidostwhi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Osteospermum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum plant. The photograph comprises a side perspective view of typical flowering plants of ‘Fidostnanowhi’ grown in container trays.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants grown during the spring in container trays, each tray with six 9-cm compartments, in a glass-covered greenhouse in De Lier, The Netherlands and under environmental conditions and cultural practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 17° C. to 35° C. and night temperatures ranged from 15° C. to 25° C. Plants were eleven weeks old when the photograph and description were taken.
