Abstract
A new and distinct cultivar of Scaevola plant named ‘Wesscaesun’, characterized by its trailing plant habit; freely branching habit; small to medium-sized leaves; freely flowering habit; and bright and light yellow-colored flowers.
Description
Botanical designation: Scaevola aemula.
Cultivar denomination: ‘WESSCAESUN’.
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 ‘Wesscaesun’.
The new Scaevola plant is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program is to create new compact and freely-branching Scaevola cultivars with attractive and unique flower coloration.
The new Scaevola plant originated from a cross-pollination made by the Inventor in Südlohn, Germany in 2007 of a proprietary selection of Scaevola aemula identified as code number 07P010, not patented, as the female, or seed, parent with a proprietary selection of Scaevola aemula identified as code number 03PSC00, not patented, as the male, or pollen, parent. The new Scaevola plant was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Südlohn, Germany in 2009.
Asexual reproduction of the new Scaevola plant by vegetative cuttings in a controlled environment in Südlohn, Germany since 2009, has shown that the unique features of this new Scaevola plant are stable and reproduced true to type in successive generations.
Plants of the new Scaevola have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Wesscaesun’. These characteristics in combination distinguish ‘Wesscaesun’ as a new and distinct cultivar of Scaevola:
-
- 1. Trailing plant habit.
- 2. Freely branching habit.
- 3. Small to medium-sized leaves.
- 4. Freely flowering habit.
- 5. Bright and light yellow-colored flowers.
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 in the following characteristics:
-
- 1. Plants of the new Scaevola have smaller and more serrated leaves than plants of the female parent selection.
- 2. Plants of the new Scaevola have smaller flowers 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 female parent selection have white-colored flowers.
Plants of the new Scaevola can be compared to plants of the male parent selection. Plants of the new Scaevola differ from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Scaevola are more freely branching than plants of the male parent selection.
- 2. Plants of the new Scaevola have finer lateral branches than plants of the male parent selection.
- 3. Plants of the new Scaevola and the male parent selection differ in flower color as plants of the male parent selection have white-colored flowers.
Plants of the new Scaevola can be compared to plants of Scaevola aemula ‘Wesscaetowhi’, disclosed in U.S. Plant Pat. No. 19,728. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Scaevola differed from plants of ‘Wesscaetowhi’ in the following characteristics:
-
- 1. Plants of the new Scaevola were larger and more trailing than plants of ‘Wesscaetowhi’.
- 2. Leaf margins of plants of the new Scaevola were more serrated than leaf margins of plants of ‘Wesscaetowhi’.
- 3. Plants of the new Scaevola had smaller flowers than plants of ‘Wesscaetowhi’.
- 4. Flowers of plants of the new Scaevola had slightly narrower petals than flowers of plants of ‘Wesscaetowhi’.
- 5. Plants of the new Scaevola and ‘Wesscaetowhi’ differed in flower color as plants of ‘Wesscaetowhi’ had white-colored flowers.
Plants of the new Scaevola can also be compared to plants of Scaevola aemula ‘Wesscaecryimp’, disclosed in U.S. Plant Pat. No. 19,703. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Scaevola differed from plants of ‘Wesscaecryimp’ in the following characteristics:
-
- 1. Plants of the new Scaevola were not as freely branching as plants of ‘Wesscaecryimp’.
- 2. Leaf margins of plants of the new Scaevola were more serrated than leaf margins of plants of ‘Wesscaecryimp’.
- 3. Plants of the new Scaevola had smaller flowers than plants of ‘Wesscaecryimp’.
- 4. Flowers of plants of the new Scaevola had smaller sepals than flowers of plants of ‘Wesscaecryimp’.
- 5. Plants of the new Scaevola and ‘Wesscaecryimp’ differed in flower color as plants of ‘Wesscaecryimp’ had white-colored flowers.
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 top perspective view of a typical flowering plant of ‘Wesscaesun’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Wesscaesun’.
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in Südlohn, Germany in 12-cm containers in a glass-covered greenhouse under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from about 16° C. to 18° C. and light levels ranging from 3,000 lux to 50,000 lux. Plants were 25 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
