Abstract
A new and distinct cultivar of Viola plant named ‘Halo Sky Blue’, characterized by its white and violet-blue colored flowers having a central yellow splotch, medium green-colored foliage, and moderate to vigorous, mounded-spreading growth habit, is disclosed.
Description
Latin name of genus and species of plant claimed: Viola cornuta.
Variety denomination: ‘Halo Sky Blue’.
The present invention relates to a new and distinct cultivar of Viola plant botanically known as Viola cornuta and hereinafter referred to by the cultivar name ‘Halo Sky Blue’.
The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during April 2007. The objective of the breeding program was the development of Viola cultivars having large flowers with distinctive flower coloration and a mounded-spreading growth habit.
The new Viola cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Viola cornuta breeding selection coded 20214-2, not patented, characterized by its violet-blue colored flowers having a central yellow splotch, medium green-colored foliage, and moderately vigorous, mounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Viola cornuta breeding selection coded 20634-4, not patented, characterized by dark purple-colored flowers having a central yellow splotch, medium green-colored foliage, and moderately vigorous, spreading growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during September 2007 in a controlled environment in Guadalupe, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since September 2007 in Guadalupe, Calif. and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Halo Sky Blue’ as a new and distinct cultivar of Viola plant:
-
- 1. White and violet-blue colored flowers having a central yellow splotch;
- 2. Medium green-colored foliage; and
- 3. Moderate to vigorous, mounded-spreading growth habit.
Plants of the new cultivar differ from plants of the female parent primarily in having a more spreading growth habit and in being more floriferous. Plants of the new cultivar differ from plants of the male parent primarily in having a different flower color and a more mounded growth habit.
Of the many commercially available Viola cultivars, the most similar in comparison to the new cultivar is ‘Etain’, not patented. However, in comparison, plants of the new cultivar differ from plants of ‘Etain’ in at least the following characteristics:
-
- 1. Plants of the new cultivar have a flower color different from plants of ‘Etain’; and
- 2. Plants of the new cultivar have a more spreading habit than plants of ‘Etain’.
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 describes the colors of ‘Halo Sky Blue’. The plants were grown in 1-gallon pots for 8 months a greenhouse in Elburn, Ill. Plants were given one pinch at transplant.
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, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2012 under natural light conditions in West Chicago, Ill. The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in Elburn, Ill. in 1-gallon pots for 8 months utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 45° F. to 65° F. (7.2° C. to 18.3° C.) during the day and approximately 35° F. to 45° F. (1.7° C. to 7.2° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
