plant named ‘BONSCA 1151’

Abstract

A new and distinct cultivar of Scaevola plant named ‘BONSCA 1151’, characterized by its mounded and semi-trailing plant habit; vigorous growth habit; freely branching habit; variegated leaves; freely flowering habit; long flowering period; bright purple-colored flowers; and good container and garden performance.

Description

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘BONSCA 1151’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scaevola plant, botanically known as Scaevola aemula and hereinafter referred to by the name ‘BONSCA 1151’.

The new Scaevola plant a product of a planned breeding program conducted by the Inventors in Yellow Rock, New South Wales, Australia. The objective of the breeding program is to create new mounding, semi-trailing and freely-flowering Scaevola plants with variegated leaves and attractive flower color.

The new Scaevola plant originated from an open-pollination in Yellow Rock, New South Wales, Australia in November, 2009 of an unnamed proprietary selection of Scaevola aemula, not patented, as the female, or seed, parent with an unknown proprietary selection of Scaevola aemula, as the male, or pollen, parent. The new Scaevola plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia on Mar. 15, 2011.

Asexual reproduction of the new Scaevola plant by vegetative cuttings in a controlled environment in Yellow Rock, New South Wales, Australia since Mar. 15, 2011 has shown that the unique features of this new Scaevola plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Scaevola 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 ‘BONSCA 1151’. These characteristics in combination distinguish ‘BONSCA 1151’ as a new and distinct Scaevola plant:

• • 1. Mounded and semi-trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Variegated leaves.
  • 5. Freely flowering habit.
  • 6. Long flowering period.
  • 7. Bright purple-colored flowers.
  • 8. Good container and garden performance.

Plants of the new Scaevola can be compared to plants of the female parent selection. Plants of the new Scaevola differ from plants of the female parent selection primarily in leaf and flower color.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula ‘Bonscalib’, disclosed in U.S. Plant Pat. No. 19,516. In side-by-side comparisons, plants of the new Scaevola differed from plants of the ‘Bonscalib’ in the following characteristics:

• • 1. Plants of the new Scaevola were larger than plants of ‘Bonscalib’.
  • 2. Plants of the new Scaevola had variegated leaves whereas plants of ‘Bonscalib’ did not have variegated leaves.
  • 3. Plants of the new Scaevola had smaller flowers than plants of ‘Bonscalib’.
  • 4. Flowers of plants of the new Scaevola and ‘Bonscalib’ differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Scaevola plant showing 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 Scaevola plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘BONSCA 1151’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘BONSCA 1151’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 20-cm containers during the summer in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Scaevola production. During the production of the plants, day temperatures ranged from 15° C. to 30° C. and night temperatures ranged from 13° C. to 25° C. Plants were four months old when the photographs were taken and five months old when the detailed description was taken.
