Abstract: A new and distinct cultivar of Angelonia plant named `Balangplum` characterized by its medium violet-colored flowers, good basal branching and moderately vigorous, upright growth habit.
Claim: What is claimed is:

1. A new and distinct cultivar of Angelonia plant named `Balangplum`, substantially as herein shown and described.
Description: Latin name of genus and species of plant claimed: Angelonia angustifolia.

Variety denomination: `Balangplum`.

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 `Balangplum`.

The new cultivar was developed by the inventor in a controlled breeding program during October 2001 at Elburn, Ill. The objective of the breeding program was the development of Angelonia cultivars with unique flower colors, good basal branchingand moderately vigorous growth habit.

The new cultivar was the result of a self-pollination of the proprietary Angelonia angustifolia breeding selection designated 175-1, not patented, characterized by its deep purple-colored flowers, medium to light green-colored foliage, tallheight, and upright growth habit. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated self-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 retainedthrough 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 `Balangplum` as a new and distinct cultivar of Angelonia plant: 1. Medium violet-colored flowers; 2. Good basal branching; and 3. Moderately vigorous, upright growth habit.

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

Of the Angelonia cultivars known to the inventor, the most similar to `Balangplum` is the Angelonia cultivar Balangdepi, U.S. Plant Pat. No. 14,656. However, in side-by-side comparisons, plants of the new cultivar differ from plants of`Balangdepi` in the following characteristics: 1. Plants of the new cultivar have a shorter growth habit compared to `Balangdepi`; 2. Plants of the new cultivar have a narrower plant diameter compared to `Balangdepi`; and 3. Plants of the new cultivarhave smaller flowers, as measured by flower length and width, compared to `Balangdepi`.

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 fromthe color values cited in the detailed description, which accurately describe the colors of `Balangplum`. The plants were grown in 10 cm pots for 11 weeks in a greenhouse at West Chicago, Ill.

FIG. 1 illustrates a side view of the overall growth and flowering habit of `Balangplum`.

FIG. 2 illustrates a close-up view of the inflorescence of `Balangplum`.

FIG. 3 illustrates a close-up view of an individual flower of `Balangplum`.

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 lengthwithout, 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 weredetermined on Apr. 13, 2005. The readings were taken between 1:00 p.m. 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 weregrown in 10 cm pots for 11 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 75.degree. F. to 85.degree. F. (25.degree. C. to 29.degree. C.) during the day and approximately 62.degree. F. to70.degree. F. (17.degree. C. to 21.degree. C.) during the night. Greenhouse light levels were maintained at approximately 6,000 to 10,000 footcandles during the day. Botanical classification: Angelonia angustifolia, cultivar Balangplum.
