Abstract

A distinct cultivar of Scaevola plant named Balscavbon, characterized by its upright and outwardly spreading plant habit; freely branching growth habit; medium green-colored leaves; and numerous violet-colored flowers.

Description

Botanical classification/cultivar designation: Scaevola humilas cultivar Balscavbon.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Scaevola plant, botanically known as Scaevola humilas and hereinafter referred to by the cultivar name ‘Balscavbon’.
The new Scaevola is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program was to develop new Scaevola cultivars with freely branching growth habit and attractive flower and foliage coloration.
The new Scaevola originated from an open-pollination made by the Inventor in November, 2000, of unnamed proprietary Scaevola humilas selections, not patented. The cultivar Balscavbon was discovered and selected by the Inventor as a flowering plant within the progeny of the stated open-pollination in a controlled environment in Arroyo Grande, Calif. in 2000.
Asexual reproduction of the new cultivar by terminal cuttings taken at Arroyo Grande, Calif. since 2000, has shown that the unique features of this new Scaevola are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balscavbon’. These characteristics in combination distinguish ‘Balscavbon’ as a new and distinct cultivar:
1. Upright and outwardly spreading plant habit.
2. Freely branching growth habit.
3. Medium green-colored leaves.
4. Numerous violet-colored flowers.
Plants of the new Scaevola differ from plants of the parent selections primarily in flower color and plant habit.
Plants of the new Scaevola can also be compared to plants of the cultivar Blue Wonder, disclosed in U.S. Plant Pat. No. 7,929. In side-by-side comparisons conducted by the Inventor in Arroyo Grande, Calif., plants of the new Scaevola and the cultivar Blue Wonder differed in the following characteristics:
1. Plants of the new Scaevola were more compact than plants of the cultivar Blue Wonder.
2. Plants of the new Scaevola were more freely branching than plants of the cultivar Blue Wonder.
3. Plants of the new Scaevola had smaller leaves with shorter petioles than plants of the cultivar Blue Wonder.
4. Plants of the new Scaevola had smaller flowers than plants of the cultivar Blue Wonder.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 more accurately describe the actual colors of the new Scaevola.
The photograph at the top of the sheet comprises a side perspective view of typical plants of ‘Balscavbon’.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Balscavbon’.
DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and for the following description were grown under conditions which closely approximate commercial production conditions in a polycarbonate-covered greenhouse in West Chicago, Ill. Plants were about 9 weeks from planting rooted cuttings in 10-cm containers. During the production of the plants, the day temperatures ranged from 24 to 26° C., night temperatures ranged from 15 to 18° C., and light levels ranged from 5,000 to 9,000 footcandles.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
