Abstract

A new and distinct Diascia plant named ‘Balwhisdarco’ characterized by its dark coral-colored flowers, medium green-colored foliage, and vigorous, mounded, and spreading growth habit.

Description

Latin name of genus and species of plant claimed: Diascia barbarae×Diascia integerimma×Diascia mollis.
Variety denomination: ‘Balwhisdarco’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Interspecific Diascia plant hereinafter referred to by the cultivar name ‘Balwhisdarco’.
The new cultivar originated in a controlled breeding program during autumn 2000, at Guadalupe, Calif. The objective of the breeding program was the development of Diascia cultivars with a well-branched, spreading growth habit, continuous flowering, and medium green-colored foliage.
The female (seed) parent of the new cultivar was the proprietary Interspecific Diascia breeding selection designated 1624-1, not patented, characterized by its large pink-colored flowers and bush type habit. The male (pollen) parent of the new cultivar was the proprietary Interspecific Diascia breeding selection designated 1646-1, not patented, characterized by its coral-colored flowers and prostrate habit. The new cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated cross in the spring of 2002.
Asexual reproduction of the new cultivar by terminal stem cuttings since spring 2002 at Guadalupe, 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 the environment, such as temperature, light intensity, and day length without, however, any variance in genotype.
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balwhisdarco’ as a new and distinct cultivar of Diascia plant:
    • 1. Dark coral-colored flowers.
    • 2. Medium green-colored foliage.
    • 3. Vigorous, mounded, and spreading growth habit.
Plants of the new cultivar differ from plants of the female parent primarily in flower color and plant habit, and from plants of the male parent primarily in flower color and plant habit.
Of the many Diascia cultivars know to the inventor, the most similar to the new cultivar is the cultivar Diastina, U.S. Plant Pat. No. 13,932. However, in side-by-side comparisons, plants of the new cultivar differed from plants of ‘Diastina’ in the following characteristics:
    • 1. Plants of the new cultivar have smaller flowers than plants of ‘Diastina’.
    • 2. Plants of the new cultivar have smaller leaves than plants of ‘Diastina’.
    • 3. The flowers of the new cultivar are a different color than those of ‘Diastina’.
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 values cited in the detailed description, which accurately describes the colors of ‘Balwhisdarco’. The plants were grown for 11 weeks in a greenhouse at West Chicago, Ill.
FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balwhisdarco’.
FIG. 2 illustrates a close-up view of an individual flower of ‘Balwhisdarco’.
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, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Oct. 9, 2004 between 10:00 and 11:00 a.m. under natural light conditions.
The following descriptions and measurements describe plants produced from terminal stem cuttings of stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at West Chicago, Ill. in 10 cm pots for 11 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 62°-75° F. (17°-24° C.) during the day and approximately 52°-60° F. (11°-15° C.) during the night. Greenhouse light levels were maintained at 5,000 to 8,000 footcandles during the day.
