Abstract

A new and distinct cultivar of Nemesia plant named ‘Balarlilabi’, characterized by its white and lavender bicolored flowers, medium green-colored foliage, and vigorous and upright growth habit.

Description

Latin name of genus and species of plant claimed: Nemesia×hybrida.

Variety denomination. ‘Balarlilabi’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant botanically known as Nemesia×hybrida and hereinafter referred to by the cultivar name ‘Balarlilabi’.

The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during September 2003. The objective of the breeding program was the development of Nemesia cultivars that are freely flowering with unique flower coloration and a well-branched, compact-upright growth habit.

The new Nemesia cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Nemesia×hybrida breeding selection designated KJGVCCE-N, not patented, characterized by its white and lavender-bicolored flowers, medium green-colored foliage, and moderately vigorous and upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Nemesia×hybrida breeding selection designated HHSDPOA-N, not patented, characterized by its white and lavender bicolored flowers, medium green-colored foliage, and moderately vigorous and upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during March 2004 in a controlled environment at Guadalupe, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since March 2004 in a greenhouse at Guadalupe, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balarlilabi’ as a new and distinct cultivar of Nemesia plant:

- 1. White and lavender bicolored flowers;
- 2. Medium green-colored foliage; and
- 3. Vigorous and upright growth habit.

Plants of the new cultivar differ from plants of the female and male parents primarily in growth vigor. As a result, plants of the new cultivar are taller and wider than plants of the female and male parents.

Of the many commercially available Nemesia cultivars, the most similar in comparison to the new cultivar is Compact Pink Innocence ‘Fleuripi’, U.S. Plant Pat. No. 16,851. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Fleuripi’ in the following characteristics:

- 1. Plants of the new cultivar have a flower color different from plants of ‘Fleuripi’; and
- 2. Plants of the new cultivar are taller than plants of ‘Fleuripi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balarlilabi’. Measurements and numerical values represent averages of typical plants. The plants were grown in 4.5 inch pots for 12 weeks in a greenhouse at West Chicago, Ill. Plants were pinched four weeks after transplant.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balarlilabi’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Oct. 24, 2007 between 1:00 p.m. and 3:00 p.m. under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. 4.5 inch pots for 12 weeks utilizing a soilless growth medium. Plants were pinched four weeks after transplant. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day.
