Angelonia plant named ‘Balangsparpi’

Abstract

A new and distinct cultivar of Angelonia plant named ‘Balangsparpi’, characterized by its dark purple-colored flowers, dark green-colored foliage, and moderately vigorous, prostrate-spreading growth habit, is disclosed.

Description

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

Variety denomination: ‘Balangsparpi’.

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 ‘Balangsparpi’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during June 2017. The objective of the breeding program was the development of Angelonia cultivars having continuous flowering and a prostrate-spreading growth habit.

The new Angelonia cultivar is the result of self-pollination of the proprietary Angelonia angustifolia breeding selection coded ANG-07167-01, not patented, characterized by its medium purple-colored flowers, medium green-colored foliage, and moderately vigorous, semi-upright growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated self-pollination during May 2018 in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since May 2018 in Arroyo Grande, 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 ‘Balangsparpi’ as a new and distinct cultivar of Angelonia plant:

• • 1. Dark purple-colored flowers;
  • 2. Dark green-colored foliage; and
  • 3. Moderately vigorous, prostrate-spreading growth habit.

Plants of the new cultivar differ from plants of the parent primarily in having a more prostrate-spreading growth habit, darker purple-colored flowers and darker green-colored foliage.

Of the many commercially available Angelonia cultivars, the most similar in comparison to the new cultivar is ANGELMIST Spreading Bluebird ‘Balangspird’, U.S. Plant Pat. No. 29,260. However, in comparison, plants of the new cultivar differ from plants of ‘Balangspird’ in at least the following characteristics:

• • 1. Plants of the new cultivar have more inflorescences per plant than plants of ‘Balangspird’; and
  • 2. Plants of the new cultivar have a dark purple petal color unlike the medium violet and white bicolored flowers of plants of ‘Balangspird’.

In addition, the new cultivar can be compared to ANGELMIST Spreading Dark Purple ‘Balangsparkl’, U.S. Plant Pat. No. 25,558. However, in comparison, plants of the new cultivar differ from plants of ‘Balangsparkl’ in at least the following characteristics:

• • 1. Plants of the new cultivar have a less violet-colored shade of flowers than plants of ‘Balangsparkl’; and
  • 2. Plants of the new cultivar have larger-sized corollas than plants of ‘Balangsparkl’.

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 ‘Balangsparpi’. The approximately 4-month-old plants were grown in 6-inch pots approximately 13 weeks in a greenhouse in West Chicago, Ill. Plants were given one pinch three weeks prior to transplant.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balangsparpi’.

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, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in February 2021 under natural light conditions in Naperville, Ill.

The following descriptions and measurements describe approximately 4-month-old 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 6-inch pots for approximately 13 weeks utilizing a soilless growth medium. Plants were given one pinch three weeks prior to transplant. Greenhouse temperatures were maintained at approximately 70° F. to 75° F. (21° C. to 24° C.) during the day and approximately 68° F. to 74° F. (20° C. to 23° C.) during the night. Supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
