Angelonia plant named ‘Balangbawi’

Abstract

A new and distinct cultivar of Angelonia plant named ‘Balangbawi’ characterized by its white-colored flowers, dark green-colored foliage, and trailing, well-branched growth habit.

Description

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

Variety denomination: ‘Balangbawi’.

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 ‘Balangbawi’.

The new cultivar was developed by the inventor in a controlled breeding program during June 2001 at Elburn, Ill. The objective of the breeding program was the development of Angelonia cultivars with freely branching, trailing, and vigorous growth habits, unique flower colors, and continuous flowering.

The female (seed) parent of the new cultivar was the proprietary Angelonia angustifolia breeding selection designated 107-19, not patented, characterized by its white-colored flowers and mounded growth habit. The male (pollen) parent of the new cultivar was the proprietary Angelonia angustifolia breeding selection designated 107-20, not patented, characterized by its violet-colored flowers and semi-spreading growth habit. 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 April 2002 in a controlled environment at Elburn, Ill.

Asexual reproduction of the new cultivar by terminal stem cuttings since April 2002 at 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 ‘Balangbawi’ as a new and distinct cultivar of Angelonia plant.

• • 1. White-colored flowers.
  • 2. Dark green-colored foliage.
  • 3. Trailing, well-branched growth habit.

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

Of the Angelonia cultivars known to the inventor, the most similar to ‘Balangbawi’ is the Angelonia cultivar Balangloud (U.S. Plant Pat. No. 15,306). However, in side-by-side comparisons, carried out at West Chicago, Ill., plants of the new cultivar differ from plants of ‘Balangloud’ primarily in growth habit.

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 describe the colors of ‘Balangbawi’. The plants were grown in 25 cm pots for 16 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balangbawi’ with three plants per pot.

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

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 color terms of ordinary significance are used. The color values were determined on Sep. 21, 2004. The readings were taken 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 14 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 75°-85° F. (24°-29° C.) during the day and approximately 62°-70° F. (17°-21° C.) during the night. Greenhouse light levels were maintained at approximately 6,000 to 10,000 footcandles during the day.
