Angelonia plant named ‘Balangloud’

Abstract

A new and distinct cultivar of Angelonia plant named ‘Balangloud’, characterized by its white-colored flowers, medium green-colored foliage, and upright and spreading growth habit.

Description

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

Variety denomination: ‘Balangloud’.

BACKGROUND OF THE INVENTION

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

The new cultivar was developed by the inventor in a controlled breeding program during February 2000, at Arroyo Grande, Calif. The objective of the breeding program was the development of Angelonia cultivars with freely branching and vigorous growth habits, unique flower colors and continuous flowering.

The female parent of the new cultivar was the proprietary Angelonia augustifolia selection designated ‘BFP-254’ (not patented) characterized by its pink-colored flowers, medium green-colored foliage, and freely branching and compact growth habit. The male parent of the new cultivar was the proprietary Angelonia augustifolia selection designated ‘BFP-272’ (not patented) characterized by its white-colored flowers, light green-colored foliage and compact, well branched growth habit. The new cultivar was discovered and selected as a single flowering plant among the progeny of the above cross-pollination by the inventor during March 2001, at Arroyo Grande, Calif. and was initially designated ‘407-8’.

Asexual reproduction of the new cultivar by terminal stem cuttings since March 2001 at Arroyo Grande, 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 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 environment, such as temperature, light intensity, and day length without, however, any variance in genotype.

It was repeatedly found that the cultivar of the present invention:

1. Exhibits white-colored flowers,

2. Forms medium green-colored foliage, and

3. Exhibits a semi-upright, well branched 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 foliage color.

Of the many Angelonia cultivars know to the inventor, the most similar to ‘Balangloud’ is ‘Anwhit’ (U.S. Plant Pat. No. 13,179). However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Anwhit’ in the following characteristics:

1. The plants of the new cultivar are shorter than the plants of ‘Anwhit’.

2. The flowers of the new cultivar are smaller than the flowers of ‘Anwhit’.

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

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where color terms of ordinary significance are used. The color values were determined on May 14, 2003. The readings were taken between 1:00 and 3:00 p.m. under natural day light conditions. The plants were produced from cuttings taken from stock plants and were 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 13 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-75° F. (18°-24° C.) during the day and approximately 50°-60° F. (10°-15° C.) during the night. Greenhouse light levels were maintained at approximately 4,000 to 7,000 footcandles during the day.
