Scaevola plant named ‘Wesscaecryimp’

Abstract

A new and distinct cultivar of Scaevola plant named ‘Wesscaecryimp’, characterized by its compact and mounded plant habit; freely branching habit with relatively short internodes; freely flowering habit; and white-colored flowers.

Description

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘WESSCAECRYIMP’

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 ‘Wesscaecryimp’.

The new Scaevola 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 flower coloration.

The new Scaevola originated from a cross-pollination made by the Inventor in Südlohn, Germany in 2003 of a proprietary selection of Scaevola aemula identified as code number 03P00, not patented, as the female, or seed, parent with a proprietary selection of Scaevola aemula identified as code number 03P10, not patented, as the male, or pollen, parent. The cultivar Wesscaecryimp was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Südlohn, Germany in 2004.

Asexual reproduction of the new Scaevola by vegetative cuttings in a controlled environment in Südlohn, 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 Wesscaecryimp 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 ‘Wesscaecryimp’. These characteristics in combination distinguish ‘Wesscaecryimp’ as a new and distinct cultivar of Scaevola:

• • 1. Compact and mounded plant habit.
  • 2. Freely branching habit with relatively short internodes.
  • 3. Freely flowering habit.
  • 4. White-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 more compact flower clusters with smaller flowers than plants of the female parent selection.

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 lateral branches than plants of the male parent selection.
  • 2. Plants of the new Scaevola have smaller 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 Top Pot White, not patented. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Scaevola differed from plants of the cultivar Top Pot White in the following characteristics:

• • 1. Plants of the new Scaevola were larger and more trailing than plants of the cultivar Top Pot White.
  • 2. Plants of the new Scaevola had longer and finer lateral branches than plants of the cultivar Top Pot White.
  • 3. Plants of the new Scaevola had larger leaves than plants of the cultivar Top Pot White.
  • 4. Plants of the new Scaevola had larger inflorescences than plants of the cultivar Top Pot White.
  • 5. Plants of the new Scaevola had larger sepals than plants of the cultivar Top Pot White.

Plants of the new Scaevola can also 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 Südlohn, Germany, plants of the new Scaevola differed from plants of the 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 the new Scaevola had more compact flower clusters with smaller flowers than plants of the cultivar Fancy.
  • 4. Plants of the new Scaevola and the cultivar Fancy differed in flower color as plants of the cultivar Fancy had violet blue-colored flowers.

During the production of the plants, day temperatures ranged from about 20° C. to 25° C. night temperatures ranged from about 16° C. to 18° C. and light levels ranged from about 3,000 lux to about 50,000 lux. Plants were about 33 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.
