USPP20332P2 - Osteospermum plant named ‘Vient Flamingo’ - Google Patents

Abstract

A new and distinct cultivar of Osteospermum plant named ‘Vient Flamingo’, characterized by its compact, semi-upright, outwardly spreading and mounded plant habit; freely branching growth habit; freely flowering habit; large daisy-type inflorescences with yellow-colored ray florets with red purple-colored venation; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘Vient Flamingo’.

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 ‘Vient Flamingo’.

The new Osteospermum is a naturally-occurring whole plant mutation of the Osteospermum ecklonis ‘Seikilrem’, disclosed in U.S. Plant Pat. No. 13,407. The new Osteospermum was discovered and selected by the Inventors as a single flowering plant within a population of plants of ‘Seikilrem’ in a controlled greenhouse environment in Isegaki, Gunma, Japan in May, 2005.

Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled environment in Isegaki, Gunma, Japan since January, 2007, has shown that the unique features of this new Osteospermum 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. 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 the new Osteospermum. These characteristics in combination distinguish ‘Vient Flamingo’ as a new and distinct cultivar of Osteospermum:

• • 1. Compact, semi-upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Large daisy-type inflorescences with yellow-colored ray florets with red purple-colored venation.
  • 5. Good garden performance.

Plants of the new Osteospermum differ from plants of the parent, ‘Seikilrem’, in the following characteristics:

• • 1. Plants of the new Osteospermum have entire leaf margins whereas plants of ‘Seikilrem’ have serrated leaf margins.
  • 2. Inflorescences of plants of the new Osteospermum and ‘Seikilrem’ differ in ray floret color as plants of ‘Seikilrem’ have bright yellow-colored ray florets.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Seipepan’, disclosed in U.S. Plant Pat. No. 16,213. In side-by-side comparisons conducted in Isegaki, Gunma, Japan, plants of the new Osteospermum differed from plants of ‘Seipepan’ in the following characteristics:

• • 1. Plants of the new Osteospermum are not as upright as plants of ‘Seipepan’.
  • 2. Plants of the new Osteospermum had smaller leaves than plants of ‘Seipepan’.
  • 3. Plants of the new Osteospermum had entire leaf margins whereas plants of ‘Seipepan’ had serrated leaf margins.
  • 4. Plants of the new Osteospermum had shorter, but broader ray florets than plants of ‘Seipepan’.
  • 5. Ray florets of plants of the new Osteospermum and ‘Seipepan’ differed in ray floret color as plants of ‘Seipepan’ had light orange-colored ray florets.

These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Vient Flamingo’ grown in a container.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Vient Flamingo’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in 15-cm containers in Toyota-city, Aichi, Japan during the late winter/early spring in a greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were three months old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 10° C. to 30° C., night temperatures ranged from 8° C. to 10° C. and light levels averaged 50,000 lux.
