A new and distinct cultivar of Osteospermum plant named ‘Sunost1302’, characterized by its compact, upright, outwardly spreading and mounding plant habit; freely branching growth habit; freely flowering habit; large daisy-type inflorescences with purple and red purple-colored ray florets; and good garden performance.

Description

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘SUNOST1302’.

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 ‘Sunost1302’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the program is to create and develop new Osteospermum plants with compact and uniformly mounded plant habit, freely flowering habit and attractive ray and disc floret coloration.

The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2009 of a proprietary selection of Osteospermum ecklonis identified as code number 07.50.014, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number 08.22.004, 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 Odense, Denmark in May, 2010.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in Odense, Denmark since November, 2010 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 ‘Sunost1302’. These characteristics in combination distinguish ‘Sunost1302’ as a new and distinct Osteospermum plant:

• • 1. Compact, upright, outwardly spreading and mounding plant habit.
  • 2. Freely branching growth habit.
  • 3. Freely flowering habit.
  • 4. Large daisy-type inflorescences with purple and red purple-colored ray florets.
  • 5. Good 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 are not as upright as plants of the female parent selection.
  • 3. Plants of the new Osteospermum and the female parent selection differ in ray floret color as plants of the female parent selection have purple-colored ray florets.

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 more compact than plants of the male parent selection.
  • 2. Plants of the new Osteospermum are not as upright as plants of the male parent selection.
  • 3. Plants of the new Osteospermum and the male parent selection differ in ray floret color as plants of the male parent selection have red-colored ray florets.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ecklonis ‘Sunost1202’, not patented. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of ‘Sunost1202’ in the following characteristics:

• • 1. Plants of the new Osteospermum were more compact than plants of ‘Sunost1202’.
  • 2. Plants of the new Osteospermum were not as upright as plants of ‘Sunost1202’.
  • 3. Plants of the new Osteospermum and ‘Sunost1202’ differed in ray floret color as plants of ‘Sunost1202’ had red-colored ray florets.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during early summer in 11-cm containers in a glass-covered greenhouse in Odense, Denmark and under cultural practices typical of commercial Osteospermum production.
