Abstract

A new and distinct cultivar of Osteospermum plant named ‘Inostepink’, characterized by its compact and upright plant habit; moderately vigorous to vigorous growth habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; long flowering period; large inflorescences with light purple and red purple-colored ray florets and purple-colored disc florets; and good summer garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘INOSTEPINK’.

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 ‘Inostepink’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the breeding program is to create compact and bushy Osteospermum plants with numerous large attractive flowers and good summer garden performance.

The new Osteospermum plant originated from a cross-pollination made by the Inventor in July, 2014 of a proprietary selection of Osteospermum ecklonis identified as code number O 13 206-2, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number O 12 223-3, not patented, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Heidesheim, Germany in April, 2015.

Asexual reproduction of the Osteospermum plant by vegetative tip cuttings in Heidesheim, Germany since June, 2015 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 combinations of 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 ‘Inostepink’. These characteristics in combination distinguish ‘Inostepink’ as a new and distinct Osteospermum plant:

- 1. Compact and upright plant habit.
- 2. Moderately vigorous to vigorous growth habit.
- 3. Freely branching habit; dense and bushy appearance.
- 4. Early and freely flowering habit.
- 5. Long flowering period.
- 6. Large inflorescences with light purple and red purple- colored ray florets and purple-colored disc florets.
- 7. Good summer garden performance.

Plants of the new Osteospermum differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Osteospermum are more compact than plants of the female parent selection.
- 2. Plants of the new Osteospermum have larger inflorescences than plants of the female parent selection.
- 3. Plants of the new Osteospermum have better summer garden performance than plants of the female parent selection.

Plants of the new Osteospermum differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Osteospermum are not as compact as plants of the male parent selection.
- 2. Ray florets of plants of the new Osteospermum are light purple and red purple in color whereas ray florets of plants of the male selection are cream-colored.
- 3. Plants of the new Osteospermum have better summer garden performance than plants of the male parent selection.

Plants of the new Osteospermum can be compared to plants of Osteospermum ecklonis ‘Osjamlipur’, disclosed in U.S. Plant Pat. No. 17,410. In side-by-side comparisons, plants of the new Osteospermum differ from plants of ‘Osjamlipur’ in the following characteristics:

- 1. Plants of the new Osteospermum are more vigorous than plants of ‘Osjamlipur’.
- 2. Ray florets of plants of the new Osteospermum are light purple and red purple in color whereas ray florets of plants of ‘Osjamlipur’ are light purple in color.
- 3. Plants of the new Osteospermum have better summer garden performance than plants of ‘Osjamlipur’.

Plants of the new Osteospermum can also be compared to plants of Osteospermum ecklonis ‘Oslalipu’, disclosed in U.S. Plant Pat. No. 18,873. In side-by-side comparisons, plants of the new Osteospermum differ from plants of ‘Oslalipu’ in the following characteristics:

- 1. Plants of the new Osteospermum are more vigorous than plants of ‘Oslalipu’.
- 2. Ray florets of plants of the new Osteospermum are light purple and red purple in color whereas ray florets of plants of ‘Oslalipu’ are lighter purple in color.
- 3. Plants of the new Osteospermum have better summer garden performance than plants of ‘Oslalipu’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter and early spring in 11.5-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial Osteospermum production.
