Abstract

A new and distinct cultivar of Arctotis plant named ‘Bonarc 1107’, characterized by its compact and semi-upright plant habit; freely branching growth habit; relatively small leaves; freely flowering habit; single-type inflorescences with white-colored ray florets; and good garden performance.

Description

Botanical designation: Arctotis hybrida.

Cultivar denomination: ‘BONARC 1107’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Arctotis plant, botanically known as Arctotis hybrida and hereinafter referred to by the name ‘Bonarc 1107’.

The new Arctotis plant is a product of a planned breeding program conducted by the Inventor in Yellow Rock, New South Wales, Australia. The objective of the breeding program is to create new compact and freely branching Arctotis plants that flower early and have attractive ray floret coloration.

The new Arctotis plant originated from a cross-pollination conducted by the Inventor in June, 2010 in Yellow Rock, New South Wales, Australia of a proprietary selection of Arctotis hybrida identified as code number 09-110, not patented, as the female, or seed, parent with a proprietary selection of Arctotis hybrida identified as code number 09-59, not patented, as the male, or pollen, parent. The new Arctotis 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 Yellow Rock, New South Wales, Australia on Aug. 11, 2011.

Asexual reproduction of the new Arctotis plant by vegetative tip cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since August, 2011 has shown that the unique features of this new Arctotis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Arctotis plant have not been observed under all possible combinations of environmental conditions and cultural practices. 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 ‘Bonarc 1107’. These characteristics in combination distinguish ‘Bonarc 1107’ as a new and distinct Arctotis plant:

• • 1. Compact and semi-upright plant habit.
  • 2. Freely branching growth habit.
  • 3. Relatively small leaves.
  • 4. Freely flowering habit.
  • 5. Single-type inflorescences with white-colored ray florets.
  • 6. Good garden performance.

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

• • 1. Plants of the new Arctotis and the female parent selection differ in ray floret color as plants of the female parent selection have peach-colored ray florets.
  • 2. Plants of the new Arctotis have shorter peduncles than plants of the female parent selection.

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

• • 1. Plants of the new Arctotis have larger inflorescences than plants of the male parent selection.
  • 2. Plants of the new Arctotis and the male parent selection differ in ray floret color as plants of the male parent selection have yellow-colored ray florets.
  • 3. Plants of the new Arctotis have shorter peduncles than plants of the male parent selection.

Plants of the new Arctotis can be compared to plants of Arctotis hybrida ‘Archley’, disclosed in U.S. Plant Pat. No. 14,667. In side-by-side comparisons, plants of the new Arctotis differ primarily from plants of ‘Archley’ in the following characteristics:

• • 1. Plants of the new Arctotis are more compact than and not as upright as plants of ‘Archley’.
  • 2. Plants of the new Arctotis have smaller leaves than plants of ‘Archley’.
  • 3. Plants of the new Arctotis and ‘Archley’ differ in ray floret color as ray florets of ‘Archley’ have yellow orange-colored ray florets.
