Latin name of genus and species of plant claimed: Salvia officinalis.
Variety denomination: ‘Balsalslent’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Salvia plant botanically known as Salvia officinalis and hereinafter referred to by the cultivar name ‘Balsalslent’.
The new cultivar originated in a controlled breeding program in Cochranville, Pennsylvania. The objective of the breeding program was the development of Salvia cultivars having numerous inflorescences while maintaining culinary appeal.
The new Salvia officinalis cultivar is a chemical-induced sport of Salvia officinalis, common sage, not patented, characterized by its medium violet-blue colored flowers, light grey-green colored foliage, and moderately vigorous, semi-upright growth habit. The chemical mutation treatment occurred during November 2016. The new cultivar was discovered as a side shoot and selected during May 2019 in a controlled environment in Cochranville, Pennsylvania.
Asexual reproduction of the new cultivar by terminal stem cuttings since May 2019 in Cochranville, Pennsylvania and Elburn, Illinois 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 ‘Balsalslent’ as a new and distinct cultivar of Salvia plant:
- 1. Medium violet-blue colored flowers;
- 2. Medium grey-green foliage; and
- 3. Moderately vigorous, compact-mounded growth habit.
Plants of the new cultivar differ from plants of the parent primarily in having more inflorescences per plant, and darker green colored calyx, a more compact-mounded growth habit, and more branches per plant.
Of the many commercially available Salvia cultivars, the most similar in comparison to the new cultivar is ‘Berggarten’, not patented. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Berggarten’ in at least the following characteristics:
- 1. Plants of the new cultivar have more inflorescences per plant than plants of ‘Berggarten’; and
- 2. Plants of the new cultivar have narrower leaves than plants of ‘Berggarten’.
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 cited in the detailed description, which accurately describes the colors of ‘Balsalslent’. The plants were approximately 14-months old. The plants were given one pinch one week before transplant into five-gallon containers. Plants were grown in an outdoor nursery in West Chicago, Illinois for approximately four months and then overwintered in a polycarbonate greenhouse in Elburn, Illinois.

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 May 2023 under natural light conditions in Naperville, Illinois.
The following descriptions and measurements describe approximately 14-month-old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in five-gallon containers in an outdoor nursery in West Chicago, Illinois for approximately four months and then overwintered in a polycarbonate greenhouse in Elburn, Illinois. Overwintering greenhouse temperatures were maintained at approximately 60° F. to 65° F. (15.5° C. to 18.3° C.) during the day and approximately 55° F. to 60° F. (12.7° C. to 15.5° C.) during the night. No supplemental lighting was provided during overwintering. Measurements and numerical values represent averages of typical plants.
