Latin name of genus and species of plant claimed: Salvia greggii.
Variety denomination: ‘Balmirvio’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Salvia plant botanically known as Salvia greggii and hereinafter referred to by the cultivar name ‘Balmirvio’.
The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during July 2013. The objective of the breeding program was the development of Salvia cultivars having large flowers and an upright-mounded growth habits.
The new Salvia cultivar was the result of a self-pollination of the proprietary Salvia greggii breeding selection coded 13-2639-2, not patented, characterized by its medium purple-colored flowers, medium green-colored foliage, and moderately vigorous, upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated self-pollination during July 2014 in a controlled environment in Guadalupe, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since July 2014 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.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balmirvio’ as a new and distinct cultivar of Salvia plant:
- 1. Deep purple-colored flowers;
- 2. Medium green-colored foliage; and
- 3. Moderately vigorous, upright-mounded growth habit.
Plants of the new cultivar differ from plants of the parent primarily in having a flower color of a different shade of purple and in having more branches per plant.
Of the many commercially available Salvia cultivars, the most similar in comparison to the new cultivar is HEATWAVE Sparkle Sage ‘EGGBEN004’, U.S. Plant Pat. No. 24,154. However, in comparison, plants of the new cultivar differ from plants of ‘EGGBEN004’ in at least the following characteristics:
- 1. Plants of the new cultivar are shorter than plants of ‘EGGBEN004’;
- 2. Plants of the new cultivar have darker purple-colored flowers than plants of ‘EGGBEN004’; and
- 3. Plants of the new cultivar have larger-sized flowers, as measured by corolla width, than plants of ‘EGGBEN004’.
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 color values citcd in the detailed description, which accurately describes the colors of ‘Balmirvio’. The plants were approximately eight-months old and grown in one-gallon containers in a greenhouse in Elburn, Ill. Plants were given one pinch prior to transplant, one pinch two weeks after transplant, and a final pinch four weeks after transplant.

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, 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, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2016 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 utilizing a soilless growth medium in one-gallon containers for approximately seven months in Elburn, Ill. Plants were transplanted in late fall from rooted cuttings and were given one pinch prior to transplant, one pinch two weeks after transplant, and a final pinch four weeks after transplant. Greenhouse temperatures were maintained during the winter months 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. For the final 12 weeks, greenhouse temperatures were maintained at approximately 65° F. to 70° F. (18.3° C. to 21.1° C.) during the day and approximately 55° F. to 60° F. (12.8° C. to 15.6° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
