plant named ‘Balarcaspim’

Abstract

A new and distinct cultivar of Angelonia plant named ‘Balarcaspim’, characterized by its dark lavender-rose colored flowers, dark green-colored foliage, and vigorous, upright growth habit growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Angelonia angustifolia.

Variety denomination: ‘Balarcaspim’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Angelonia plant botanically known as Angelonia angustifolia and hereinafter referred to by the cultivar name ‘Balarcaspim’.

The new cultivar originated in a controlled breeding program in Elburn, Ill. during January 2009. The objective of the breeding program was the development of Angelonia cultivars having large flowers, unique flower coloration, continuous flowering, and a vigorous, freely branching, and upright to semi-upright growth habit.

The new Angelonia cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Angelonia angustifolia breeding selection coded 516-3,6-1, not patented, characterized by its dark burgundy-magenta and white bicolored flowers, dark green-colored foliage, and moderately vigorous, semi-upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Angelonia angustifolia breeding selection coded 573-2, not patented, characterized by its dark violet-colored flowers, dark green-colored foliage, and vigorous, 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 November 2009 in a controlled environment in Elburn, Ill.

Asexual reproduction of the new cultivar by terminal stem cuttings since November 2009 in 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 ‘Balarcaspim’ as a new and distinct cultivar of Angelonia plant:

• • 1. Dark lavender-rose colored flowers;
  • 2. Dark green-colored foliage; and
  • 3. Vigorous, upright growth habit.

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

Of the many commercially available Angelonia cultivars, the most similar in comparison to the new cultivar is ARCHANGEL Raspberry ‘Balarcasp’, U.S. Plant patent application Ser. No. 13/134,195, now abandoned. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Balarcasp’ in at least the following characteristics:

• • 1. Plants of the new cultivar are shorter than plants of ‘Balarcasp’;
  • 2. Plants of the new cultivar have a slightly darker flower color than plants of ‘Balarcasp’;
  • 3. Plants of the new cultivar have more flowers per inflorescence than plants of ‘Balarcasp’; and
  • 4. Plants of the new cultivar have a smaller flower, as measured by corolla length and width, than plants of ‘Balarcasp’.

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 ‘Balarcaspim’. The plants were grown in 4-inch pots for 7 weeks in a greenhouse in West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balarcaspim’.

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

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, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in April 2012 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 7 weeks utilizing a soilless growth medium. 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. Measurements and numerical values represent averages of typical plants.
