Nemesia plant named ‘Balaroyal’

Abstract

A new and distinct cultivar of Nemesia plant named ‘Balaroyal’ characterized by its deep purple-colored flowers with yellow “eye”, medium green-colored foliage, and upright and spreading growth habit.

Description

Latin name of genus and species of plant claimed: Nemesia foetans.

Variety denomination: ‘Balaroyal’.

BACKGROUND OF THE INVENTION

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

The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during the spring of 2002. The objective of the breeding program was the development of Nemesia cultivars with a well-branched, spreading growth habit, unique flower colors, and continuous flowering.

The female (seed) parent of ‘Balaroyal’ was the proprietary Nemesia foetans selection designated 2113-1-4-3, not patented, characterized by its light pink-colored flowers and well-branched habit. The male (pollen) parent of ‘Balaroyal’ was the proprietary Nemesia foetans selection designated 2068-2-3-1, not patented, characterized by its deep blue-colored flowers, average branching habit, and late blooming time. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross-pollination during the autumn of 2002 at Guadalupe, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since the autumn of 2002 at Guadalupe, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all 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 ‘Balaroyal’ as a new and distinct cultivar of Nemesia plant:

• • 1. Deep purple-colored flowers with yellow “eye”.
  • 2. Medium green-colored foliage.
  • 3. Upright and spreading growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in flower color and from plants of the male parent primarily in flower color.

Of the Nemesia cultivars known to the inventor, the most similar to the new cultivar is ‘Balartublu’, U.S. Plant patent application Ser. No. 10/734,859. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Balartublu’ in the following characteristics:

• • 1. Plants of the new cultivar have larger leaves than plants of ‘Balartublu’.
  • 2. Plants of the new cultivar have lighter, brighter flower color than plants of ‘Balartublu’.

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 more accurately describe the colors of ‘Balaroyal’. The plants were grown in 10 cm pots for 9 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates the overall growth habit of the new cultivar.

FIG. 2 illustrates a close-up view of an individual flower of the new cultivar.

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 Sep. 24, 2004 between 1:00 and 3:00 p.m. under natural light conditions.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 9 weeks while utilizing a soil-less growth medium. Greenhouse temperatures were maintained at approximately 65° to 75° F. (18° to 24° C.) during the day and approximately 50° to 60° F. (10° to 15° C.) during the night. Daytime greenhouse light levels were maintained at approximately 4,000 to 7,000 footcandles.
