STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT & ASSIGNEE

The Inventor/Applicant and Assignee, Bonza Botanicals Pty. Ltd. of Yellow Rock, New South Wales, Australia, assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Bonsc 16100’.

The new Scaevola plant 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, mounding Scaevola plants with numerous attractive flowers.

The new Scaevola plant originated from an open-pollination in Yellow Rock, New South Wales, Australia in December, 2015 of a proprietary selection of Scaevola aemula identified by the code number 14-174, not patented, as the female, or seed, parent with an unidentified proprietary selection of Scaevola aemula, as the male, or pollen, parent. The new Scaevola plant was discovered and selected by the Inventor 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 in December, 2016.

Asexual reproduction of the new Scaevola plant by vegetative tip cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since December, 2016 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 ‘Bonsc 16100’. These characteristics in combination distinguish ‘Bonsc 16100’ as a new and distinct Scaevola plant:

• • 1. Relatively compact and mounding to outwardly spreading plant habit.
  • 2. Freely branching habit.
  • 3. Early and freely flowering habit.
  • 4. Long flowering period.
  • 5. Flowers that are deep reddish purple in color.
  • 6. 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 primarily from plants of the female parent selection in flower color as plants of the new Scaevola have deep reddish purple-colored flowers whereas plants of the female parent selection have deep blue-colored flowers.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula ‘Bonsca 1430’, disclosed in U.S. Plant Pat. No. 28,820. In side-by-side comparisons, plants of the new Scaevola differ from plants of the ‘Bonsca 1430’ in the following characteristics:

• • 1. Plants of the new Scaevola are more compact than plants of ‘Bonsca 1430’.
  • 2. Plants of the new Scaevola are have thicker lateral branches with shorter internodes than plants of ‘Bonsca 1430’.
  • 3. Plants of the new Scaevola are more freely flowering than plants of ‘Bonsca 1430’.
  • 4. Plants of the new Scaevola and ‘Bonsca 1430’ differ in flower color as flowers of plants of the new Scaevola are deep reddish purple in color whereas flowers of plants of ‘Bonsca 1430’ are deep violet in color.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 24-cm containers 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 three months old when the photographs and the detailed description were taken.
