USPP19117P2 - Scaevola plant named ‘SCAX0226’ - Google Patents

Abstract

A new and distinct cultivar of Scaevola plant named ‘SCAX0226’, characterized by its compact, mounded and outwardly spreading plant habit; freely branching habit; freely flowering habit; and violet-colored flowers.

Description

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘SCAX0226’.

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 ‘SCAX0226’.

The new Scaevola is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new freely-flowering Scaevola cultivars with attractive flower color.

The new Scaevola originated from a cross-pollination made by the Inventor in Cobbitty, New South Wales, Australia in October, 2001, of a proprietary selection of Scaevola aemula identified as code number 01.1.1, not patented, as the female, or seed, parent with a proprietary selection of Scaevola aemula identified as code number 01.1.2, not patented, as the male, or pollen, parent. The cultivar SCAX0226 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Cobbitty, New South Wales, Australia in October, 2002.

Asexual reproduction of the new Scaevola by terminal cuttings in a controlled environment in Cobbitty, New South Wales, Australia since October, 2002, 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 SCAX0226 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, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SCAX0226’. These characteristics in combination distinguish ‘SCAX0226’ as a new and distinct cultivar of Scaevola:

• • 1. Compact, mounded and outwardly spreading plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Violet-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 are more compact than plants of the female parent selection.
  • 2. Plants of the new Scaevola have smaller leaves than plants of the female parent selection.
  • 3. Plants of the new Scaevola have violet-colored flowers whereas plants of the female parent selection have purple-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 compact than and not as trialing as plants of the male parent selection.
  • 2. Plants of the new Scaevola have larger leaves than plants of the male parent selection.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula cultivar Newon, disclosed in U.S. Plant Pat. No. 10,584. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Scaevola differed from plants of the cultivar Newon in the following characteristics:

• • 1. Plants of the new Scaevola were more compact than plants of the cultivar Newon.
  • 2. Plants of the new Scaevola had smaller leaves than plants of the cultivar Newon.
  • 3. Flowers of plants of the new Scaevola and the cultivar Newon differed in flower color as plants of the cultivar Newon had purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘SCAX0226’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical flowers of ‘SCAX0226’.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Bonsall, Calif. in one-gallon containers in an outdoor nursery during the summer under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from about 18° C. to 38° C. and night temperatures ranged from about 16° C. to 24° C. Plants were about seven weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
