Description

Botanical denomination: Salvia pratensis hybrid.

Cultivar designation: ‘Snow Kiss’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosure, in the form of a catalog with a photograph and brief description was on Aug. 20, 2019 maintained by Gootjes-Allplant BV in The Netherlands. Gootjes-Allplant BV obtained their plants and all information about the new plant indirectly from the inventor. No plants of Salvia ‘Snow Kiss’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

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 ‘Snow Kiss’ or as the new plant. The new plant was selected from a cross under the direction of the inventor in the late spring of 2014 between ‘Pretty in Pink’ U.S. Plant Pat. No. 29,550 as the female or seed parent and the male or pollen parent is unnamed sibling of ‘Pretty in Pink’ (not patented). The cross was performed within the breeding area of a wholesale perennial nursery in Zeeland, Mich., USA. Seed was collected on Jun. 11, 2014 and sown at the same nursery. The new plant was initially evaluated in the summer of 2016 and assigned the breeder code 14-2-2 through the trial process prior to assigning the cultivar name.

The new Salvia was further evaluated and asexually propagated initially by division, by basal cuttings taken at the same nursery in Zeeland, Mich., USA in 2017 and later from shoot tip tissue culture. Evaluation of these and further cutting grown plants shows that Salvia ‘Snow Kiss’ continues to be stable and produce true to type plants in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of Salvia ‘Snow Kiss’ 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 ‘Snow Kiss’ can be closely compared to Salvia ‘White Profusion’

U.S. Plant patent application Ser. No. 16/602,703, ‘Florsalwhite’ U.S. Plant Pat. No. 21,243, ‘Bumblesnow’ U.S. Plant Pat. No. 31,399, and ‘Snow Hill’ (not patented). ‘White Profusion’, ‘Bumblesnow’, ‘Florsalwhite’ and ‘Snow Hill’ all are Salvia nemorosa types with much smaller flowers. ‘Snow Kiss’ is slightly taller in flower habit than ‘Snow Hill’, ‘White Profusion and ‘Florsalwhite’ and significantly taller than ‘Bumblesnow’. ‘Snow Hill’ is much narrower in habit, and all the other comparison cultivars are more broad mounded than the new plant. All of the above comparison cultivars have pure white flowers without the pale purple blush. The female parent has similar-sized flowers, but of lavender pink flowers, and darker pink calyxes, deep purplish-red flower buds and grey-purple tinting of the peduncle.

The following characteristics in combination distinguish Saliva ‘Snow Kiss’ as a new and distinct cultivar from all other cultivars known to the inventor:

    • 1. Large white flowers with a pale purple blush densely arranged in verticils;
    • 2. Stiff, upright, chartreuse, heavily-branched stems;
    • 3. White flower buds with a blush of pale purple;
    • 4. Dense, rounded, strong, vigorous and winter-hardy habit;
    • 5. Rugose, dark olive-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia ‘Snow Kiss’. 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 three-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. Plant growth regulators have been used in greenhouse grown trials only.

FIG. 1 shows the plant habit in full flower in a landscape.

FIG. 2 shows a close-up of the flower scape with the buds, flowers, stems and calyxes.

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 ‘Snow Kiss’ 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 three-year old plants growing in an outdoor full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. and greenhouse forced two-year old plants. Plants were given supplemental water and fertilizer and plant growth regulators were used for the greenhouse trials only.
