Abstract: A new and distinct cultivar of Scaevola plant named `Wesscaetob`, characterized by its compact and mounded plant habit; freely branching habit; freely flowering habit; and violet blue-colored flowers.
Claim: It is claimed:

1. A new and distinct Scaevola plant named `Wesscaetob` as illustrated and described.
Description: Botanical designation: Scaevolaaemula.

Cultivar denomination: `Wesscaetob`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scaevola, botanically known as Scaevola aemula, and hereinafter referred to by the name `Wesscaetob`.

The new Scaevola is a product of a planned breeding program conducted by the Inventor in Sudlohn, Germany The objective of the breeding program is to create new compact and freely-flowering Scaevola cultivars.

The new Scaevola originated from a cross-pollination made by the Inventor in Sudlohn, Germany in 2003 of the Scaevola aemula cultivar Brilliant, disclosed in U.S. Plant Pat. No. 12,099, as the female, or seed, parent with a proprietaryselection of Scaevola aemula identified as code number 03P61, not patented, as the male, or pollen, parent. The cultivar Wesscaetob was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in acontrolled environment in Sudlohn, Germany in 2004.

Asexual reproduction of the new Scaevola by terminal cuttings in a controlled environment in Sudlohn, Germany since 2004, has shown that the unique features of this new Scaevola are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Wesscaetob has 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, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Wesscaetob`. These characteristics in combination distinguish `Wesscaetob` as a new and distinct cultivar of Scaevola: 1. Compact andmounded plant habit. 2. Freely branching habit. 3. Freely flowering habit. 4. Violet blue-colored flowers.

Plants of the new Scaevola can be compared to plants of the female parent, the cultivar Brilliant. Plants of the new Scaevola differ from plants of the cultivar Brilliant in the following characteristics: 1. Plants of the new Scaevola are morecompact than plants of the cultivar Brilliant. 2. Plants of the new Scaevola have smaller leaves than plants of the cultivar Brilliant. 3. Plants of the new Scaevola have smaller flowers than plants of the cultivar Brilliant.

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 have finer branchesthan plants of the male parent selection. 2. Plants of the new Scaevola have longer leaves than plants of the male parent selection. 3. Plants of the new Scaevola have larger flowers than plants of the male parent selection.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula cultivar Fancy, disclosed in U.S. Plant Pat. No. 9,867. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Scaevola differed from plants ofthe cultivar Fancy in the following characteristics: 1. Plants of the new Scaevola were more compact and mounding than plants of the cultivar Fancy. 2. Plants of the new Scaevola had smaller leaves than plants of the cultivar Fancy. 3. Plants of thenew Scaevola had smaller flowers than plants of the cultivar Fancy. 4. Flowers of plants of the new Scaevola and the cultivar Fancy differed in flower color as flowers of plants of the cultivar Fancy had a white-colored band at the base of the petals.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Scaevola, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Scaevola. The photograph comprises a side perspective view of a typical flowering plant of `Wesscaetob` grown in a container.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Sudlohn, Germany in containers in a glass-covered greenhouse during the summer under conditions which closely approximate commercial production. Duringthe production of the plants, day temperatures ranged from about 20.degree. C. to 25.degree. C., night temperatures ranged from about 16.degree.C. to 18.degree.C. and light levels ranged from about 3,000 lux to about 50,000 lux. Plants were aboutfour months 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.
