Abstract

The new and distinct cultivar of perennial Salvia plant named ‘Midnight Model’ characterized by its very large, striking, strong violet flowers with dark green calyxes densely arranged in verticils, compact rounded habit with stiff, upright, branched stems, large, rugose, dark-green foliage, strong vigorous growth rate, and winter-hardy.

Description

Botanical denomination: Salvia pratensis (Linnaeus).

Cultivar designation: ‘Midnight Model’.

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 ‘Midnight Model’ or as the new plant. The new plant was from open pollinated seed collected by the inventor in the summer of 2013 at a wholesale perennial nursery in Zeeland, Mich., USA. The female (seed) parent ‘Pink Dawn’ U.S. Plant Pat. No. 26,343 and male (pollen) parent is unknown. Salvia ‘Midnight Model’ was placed in comparison trials at a the same nursery in Zeeland, Mich. in the summer of 2014 and assigned the breeder code 13-10-2 during the initial trials in 2014 and final trials in the summer of 2015 when it was approved for introduction. The plant was initially asexually propagated by basal vegetative shoot cuttings taken in 2014. The resulting plants of Salvia ‘Midnight Model’ asexually propagated at the same wholesale perennial nursery in Zeeland, Mich. have been found to be true to type and stable in successive generations.

No plants of Veronica ‘Midnight Model’ have been sold in this country, or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which was disclosed or sold within one year of the filing of this application and was either derived directly or indirectly from the inventor.

SUMMARY OF THE INVENTION

Plants of Salvia ‘Midnight Model’ 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, etc. without, however, any variance in genotype.

The nearest comparison cultivars are Salvia ‘Twilight Serenade’ (not patented) and Salvia ‘Indigo’ (not patented). Salvia ‘Midnight Model’ is more compact and shorter in habit, with larger flowers of more strong violet than that of the purple flowers of ‘Indigo’. Compared with ‘Twilight Serenade’, the new plant is slightly taller and the flowers of ‘Twilight Serenade’ are slightly more purplish.

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

• • 1. Very large, striking, strong violet colored flowers dark green calyxes densely arranged in verticils from late spring into early summer;
  • 2. Full mounded habit with many stiff, upright, branched flowering stems;
  • 3. Strong, vigorous and winter-hardy growth;
  • 4. Large, rugose, dark-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia ‘Midnight Model’. 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 two-year-old plant grown in a partially shaded greenhouse at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed. No plant growth regulators have been used.

FIG. 1 shows the plant habit in full flower in a full-sun garden.

FIG. 2 shows a close-up of the flower scape with the buds, calyxes and vivid violet-blue 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 ‘Midnight Model’ 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 partially shaded greenhouse and also in a full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich.
