plant named ‘Blue by You’

Abstract

A new and distinct cultivar of Salvia plant named ‘Blue by You’, characterized by its deep violet-blue colored flowers, medium green-colored foliage, and moderately vigorous, upright-mounded growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Salvia hybrid.

Variety denomination: ‘Blue by You’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Salvia plant botanically known as Salvia hybrid and hereinafter referred to by the cultivar name ‘Blue by You’.

The new cultivar originated in a controlled breeding program in Cochranville, Pa. during June 2011. The objective of the breeding program was the development of sterile Salvia cultivars with good repeat blooming, and excellent weather tolerance.

The new Salvia cultivar was the result of cross-pollination. The female (seed) parent of the new cultivar is Salvia nemorosa ‘May Night’, also known as ‘Mainacht’, not patented, characterized by its dark violet-colored flowers, medium green-colored foliage, and moderately vigorous, semi-upright growth habit. The male (pollen) parent of the new cultivar is Salvia pratensis ‘Rose Rhapsody’, not patented, characterized by its medium pink-colored flowers, medium green-colored foliage, and moderately vigorous, semi-upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during July 2012 in a controlled environment in Cochranville, Pa.

Asexual reproduction of the new cultivar by terminal stem cuttings since July 2012 in Cochranville, Pa. 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 ‘Blue by You’ as a new and distinct cultivar of Salvia plant:

• • 1. Deep violet-blue 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 female parent primarily in having larger flowers and larger foliage. Plants of the new cultivar differ from plants of the male parent primarily in having a different flower color and more mounded growth habit.

Of the many commercially available Salvia cultivars, the most similar in comparison to the new cultivar is FASHIONISTA ‘Midnight Model’, U.S. Plant Pat. No. 29,498. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Midnight Model’ in at least the following characteristics:

• • 1. Plants of the new cultivar have smaller corollas than plants of ‘Midnight Model’;
  • 2. Plants of the new cultivar have a darker flower color than plants of ‘Midnight Model’; and
  • 3. Plants of the new cultivar is male-sterile unlike plants of ‘Midnight Model’.

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 ‘Blue by You’. The plants were approximately four months old. The plants were grown in one-gallon containers for approximately 9 weeks in a greenhouse in Elburn, Ill. followed by 1 week in an open-sided polyhouse in West Chicago, Ill. Plants were given two pinches, one at one week before transplant and one two 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 July 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately four-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 one-gallon containers for approximately 9 weeks in a greenhouse in Elburn, Ill. followed by 2 weeks in an open-sided polyhouse in West Chicago, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant. Greenhouse temperatures in Elburn, Ill. 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.
