plant named ‘Sweet Petite’

Abstract

The new and distinct cultivar of perennial Salvia plant named ‘Sweet Petite’ characterized by its very large lavender-pink flowers from dark rosy-red buds, densely arranged in verticils. The new plant has a short, compact habit with stiff, upright, heavily-branched stems and a strong vigorous growth rate and gray-green foliage. ‘Sweet Petite’ is useful for landscaping as a specimen plant or en masse.

Description

Botanical denomination: Salvia pratensis.

Cultivar designation: ‘Sweet Petite’.

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

The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2018. The claimed plant was first sold on Jul. 9, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Salvia ‘Sweet Petite’ 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 ‘Sweet Petite’ or as the new plant. The new plant was selected from a block of seedlings resulting from an open pollination in late spring of 2013 with the unreleased, proprietary hybrid known as 12-23-09 as the female or seed parent and the male parent is unknown but may have been any sage from a large number of other hybrids and selected cultivars within the breeding area of a wholesale perennial nursery in Zeeland, Mich., USA. Seed was collected in the summer of 2013 and sown at the same nursery. The new plant was initially evaluated in the summer of 2015 and assigned the breeder code 13-40-1 through the trial process.

The new Salvia was further evaluated and asexually propagated initially by division and later by basal cuttings taken at the same nursery in Zeeland, Mich., USA in 2015. Evaluation of these and further cutting grown plants shows that Salvia ‘Sweet Petite’ continues to be stable and produce true to type plants in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of Salvia ‘Sweet Petite’ 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 ‘Sweet Petite’ can be closely compared to Salvia ‘Sweet 16’ U.S. Plant Pat. No. 24,311, ‘Ballerina Pink’ U.S. Plant Pat. No. 29,957, ‘Pretty in Pink’ U.S. Plant Pat. No. 29,550 and Salvia ‘Pink Dawn’ U.S. Plant Pat. No. 26,343. ‘Sweet 16’ flowers for a shorter season on taller and broader plants. ‘Ballerina Pink’ has softer, lighter pink flowers on slightly taller plants. ‘Pretty in Pink’ has more vibrant lavender-pink flowers on slightly larger plants. The stems and calyxes of ‘Pink Dawn’ are much darker pigmented with greyed-purple than the new plant, the flowers are darker, deep, purplish pink and the habit is taller than the new plant. The female parent, 12-23-09 is taller in habit and has flowers of a different hue. Further comparison with the female parent is not possible as it was not maintained.

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

1. Very large lavender pink flowers densely arranged in verticils;

2. Stiff, upright, heavily-branched stems;

3. Dark rosy-red flower buds;

4. Short, compact, rounded, strong, vigorous and winter-hardy habit;

5. Rugose gray-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia ‘Sweet Petite’. 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 an open, full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed.

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 ‘Sweet Petite’ 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 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.
