plant named ‘Indiglo Girl’

Abstract

The new and distinct cultivar of perennial Salvia plant named ‘Indiglo Girl’ characterized by its large strong violet-colored flowers densely arranged in dense verticils, with upright habit and stiff, upright; heavily-branched stems and strong vigorous growth rate and large deep-green foliage. Salvia ‘Indiglo Girl’ is especially useful for landscaping and containerized ornamentals by itself or in combination with other plants.

Description

Botanical denomination: Salvia nemorosa (Linnaeus).

Cultivar designation: ‘Indiglo Girl’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of ornamental sage plant hereinafter referred to by the cultivar name Salvia ‘Indiglo Girl’ or as the new plant. The new plant was the result of a controlled pollination between the proprietary unreleased hybrid known only by the breeder code number Salvia 12-31-02 (not patented) (a seedling of ‘Pink Dawn’ U.S. Plant Pat. No. 26,343) as the female patent and ‘Violet Riot’ U.S. Plant Pat. No. 26,273 as the male parent at a wholesale perennial nursery in Zeeland, Mich., USA. The seeds were harvested in the fall of 2013 and the single specific seedling that developed into the new Salvia was assigned the breeder code 13-10-22 through the evaluation process. The new plant was first selected for further evaluation in the summer of 2014 and selected for final evaluation in the summer of 2016. The first asexual propagation was performed in the summer of 2014 by basal cuttings at the same nursery in Zeeland, Mich. ‘Indiglo Girl’ has proven that it is stable and reliably produces true to type plants in successive generations of asexual propagation.

No plants of Salvia ‘Indiglo Girl’ have been sold or disclosed in this country, or anywhere in the world, by this or any name, more than one year prior to the filing of this application, with the exception of that which was sold or disclosed either directly or indirectly from the inventor and within one year from the filing of this application.

SUMMARY OF THE INVENTION

Plants of Salvia ‘Indiglo Girl’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, nutrition and light intensity without, however, any variance in genotype.

Salvia ‘Indiglo Girl’ can be most closely compared to ‘Blue Marvel’ U.S. Plant Pat. No. 27,018 and ‘Midnight Model’ U.S. Plant Pat. No. 29,498. ‘Blue Marvel’ is smaller in habit, the foliage is larger and the flower color is slightly different colored. ‘Midnight Model’ has darker colored flowers and is slightly taller in habit. The female parent, Salvia 12-31-02, has larger pink flowers and the habit is more spreading and less upright. The male parent has smaller, more violet flowers and more branching with smaller foliage. The new plant can also be compared to ‘Haeumanarc’ U.S. Plant Pat. No. 13,322 which is much shorter in habit with smaller and has a lighter bluish flower color. Compared with Salvia ‘Bumbleblue’ U.S. Plant patent application Ser. No. 15/731,914, the new plant is much larger in habit with larger leaves and flowers.

The following characteristics in combination distinguish Saliva ‘Indiglo Girl’ as a new and distinct cultivar:

• • 1. Large, strong violet-colored flowers densely arranged in tight verticils;
  • 2. Upright habit with stiff, upright, heavily-branched stems;
  • 3. Strong, vigorous and winter-hardy;
  • 4. Large, rugose, deep-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia ‘Indiglo Girl’. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color. The plant used in the photographs was a one-year old plant grown in an open, full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed. No stem pinching or plant growth regulators have been used.

FIG. 2 shows a close-up of the flower scape with the buds and strong violet petal color.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references except where common dictionary terms are used are based on the 2015 edition of The Royal Horticultural Society Colour Chart. Salvia ‘Indiglo Girl’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and plant maturity levels, but without any change in the genotype. The following observations and size descriptions are based on two-year old plants growing in a greenhouse with minimal shading in addition to two-year-old plants grown in a full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. Plants were given supplemental water and fertilizer but no plant growth regulators were used.
