Abstract

A new and distinct cultivar of Scaevola plant named ‘DSCAWINDST’, characterized by its outwardly spreading and mounded plant habit; freely branching habit; relatively broad leaves; early and freely flowering habit; white and purplish blue bi-colored flowers; and good container and garden performance.

Description

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘DSCAWINDST’.

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 ‘DSCAWINDST’.

The new Scaevola plant a product of a planned breeding program conducted by the Inventor in Mishmar Hashiva, Israel. The objective of the breeding program is to create new compact, spreading and early-flowering Scaevola plants with numerous attractive bi-colored flowers.

The new Scaevola plant originated from an open-pollination in Mishmar Hashiva, Israel in March, 2015 of a proprietary selection of Scaevola aemula identified by the code number 14-1050, 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 Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Mishmar Hashiva, Israel on Mar. 15, 2016.

Asexual reproduction of the new Scaevola plant by vegetative tip cuttings in a controlled greenhouse environment in Mishmar Hashiva, Israel since Mar. 15, 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 ‘DSCAWINDST’. These characteristics in combination distinguish ‘DSCAWINDST’ as a new and distinct Scaevola plant:

• • 1. Outwardly spreading and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Relatively broad leaves.
  • 4. Early and freely flowering habit.
  • 5. White and purplish blue bi-colored flowers.
  • 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 the following characteristics:

• • 1. Plants of the new Scaevola are more vigorous than and not as compact as plants of the female parent selection.
  • 2. Plants of the new Scaevola have darker leaves than plants of the female parent selection.
  • 3. Plants of the new Scaevola and the female parent selection differ in flower color as plants of the new Scaevola have white and purplish blue bi-colored flowers whereas plants of the female parent selection have lavender-colored flowers.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula ‘Wesscaedia’, disclosed in U.S. Plant Pat. No. 15,431. In side-by-side comparisons, plants of the new Scaevola differ from plants of the ‘Wesscaedia’ in the following characteristics:

• • 1. Plants of the new Scaevola are more mounding than and not as trailing as plants of ‘Wesscaedia’.
  • 2. Plants of the new Scaevola have shorter internodes than plants of ‘Wesscaedia’.
  • 3. Plants of the new Scaevola flower earlier than plants of ‘Wesscaedia’.

Plants of the new Scaevola can also be compared to plants of the Scaevola aemula ‘Brillant’, disclosed in U.S. Plant Pat. No. 12,099. In side-by-side comparisons, plants of the new Scaevola differ from plants of the ‘Brillant’ in the following characteristics:

• • 1. Plants of the new Scaevola are more mounding than and not as trailing as plants of ‘Brillant’.
  • 2. Plants of the new Scaevola are not as vigorous as plants of ‘Brillant’.
  • 3. Plants of the new Scaevola have smaller flowers than plants of ‘Brillant’.
  • 4. Plants of the new Scaevola and ‘Brillant’ differ in flower color as plants of the new Scaevola have white and purplish blue bi-colored flowers whereas plants of ‘Brillant’ have blue purple-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 13-cm containers in a greenhouse and finished in an outdoor nursery in Mishmar Hashiva, Israel and under cultural practices typical of commercial Scaevola production. During the production of the plants, day temperatures ranged from 15° C. to 28° C. and night temperatures ranged from 10° C. to 15° C. Plants were eight weeks old when the photographs and the detailed description were taken.
