Abstract

A new and distinct Diascia plant named ‘Balwhiswhit’ characterized by its white-colored flowers, medium green-colored foliage and a spreading and trailing growth habit.

Description

Latin name of genus and species of plant claimed: Diascia hybrid.
Variety denomination: ‘Balwhiswhit’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Interspecific Diascia plant hereinafter referred to by the cultivar name ‘Balwhiswhit’.
The new cultivar was developed by the inventor in a controlled breeding program during the summer of 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 ‘Balwhiswhit’ was the proprietary Interspecific Diascia selection designated ‘377-3’ (not patented) characterized by its apricot-colored flowers, medium green-colored foliage and prostrate habit. The male (pollen) parent of ‘Balwhiswhit’ was the proprietary Interspecific Diascia selection designated ‘399-1’ (not patented) characterized by its light lavender-colored flowers, light green-colored foliage, and spreading, mounded habit. Both parental cultivars have the following species in their background, Diascia barbarae, Diascia integerimma, and Diascia mollis. ‘Balwhiswhit’ was discovered and selected in the winter of 2000 as a single flowering plant from within the progeny of the above stated cross-pollination and was initially designated ‘601-1m-2-2’.
Asexual reproduction of the new cultivar by terminal stem cuttings taken since the winter of 2000 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
It has been repeatedly found that the cultivar of the present invention:
1. Exhibits white-colored flowers,
2. Forms medium green-colored foliage, and
3. Exhibits a spreading and trailing 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 flower color and foliage color.
Of the many Diascia cultivars know to the inventor, the most similar to ‘Balwhiswhit’ is the cultivar ‘Iceburg’ (not patented). However, in side-by-side comparisons, plants of ‘Balwhiswhit’ have larger flowers than plants of the cultivar ‘Iceburg’.
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 ‘Balwhiswhit’. The plants were grown for 10 weeks in a greenhouse at West Chicago, Ill.
FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balwhiswhit’.
FIG. 2 illustrates a close-up view of an individual flower of ‘Balwhiswhit’.
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. 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 general color terms of ordinary dictionary significance are used. The color values were determined on Jul. 23, 2003. The readings were taken between 1:00 and 3:00 p.m. under natural light conditions. The plants were produced from terminal stem 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 10 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.
