plant named ‘Pinky Promise’
A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named ‘Pinky Promise’ with numerous, single, lightly-sweet fragrant flowers producing a full rounded face. Each flower has five overlapping petals that are fuchsia-pink colored with small darker red bar in the center. Petals have moderate dentate apices. Flowering season is strong for four weeks beginning in late spring nearly completely covering the dome of the plant. The habit is compact, heavily branched, moderately spreading, and dense, with lightly glaucous blue-green foliage.

Botanical denomination: Dianthus hybrid.
Cultivar designation: ‘Pinky Promise’.STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)
The first enabling disclosure as a sale of the new plant was on Oct. 22, 2021, by Green Leaf Plants® (a division of Aris Horticulture, Inc.) which obtained the new plant from Walters Gardens, Inc. Walters Gardens, Inc. also introduced the new plant on Feb. 1, 2022, in the form of photographs and a brief description on a website operated by Walters Gardens, Inc. followed on Jun. 8, 2022, as a photograph and brief description in the “Walters Gardens 2022-2023 Catalog.” Walters Gardens, Inc. obtained the plant and all information relating thereto, from the inventor. No plants of Dianthus ‘Pinky Promise’ 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 and would therefore be a 35 U.S.C. § 102b exception.BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct cultivar of carnation or pinks from the genus Dianthus and was given the cultivar name ‘Pinky Promise’. The new plant was the result of an intentional cross on Oct. 21, 2014, under the direction of the inventor between the proprietary, unreleased, unnamed hybrid known only by the breeder code 11-265-1 (not patented) as the female or seed parent and the male or pollen parent is the proprietary, unreleased, unnamed hybrid known only by the breeder code 12-60-1 (not patented). The cross was harvested and sown in the early spring of 2015. The new hybrid was first selected from trials at a wholesale perennial nursery in Zeeland, Mich. during the summer of 2017 as a single seedling clone and given the breeder code number 14-44-1 later in the evaluation processes. Dianthus ‘Pinky Promise’ has been asexually propagated at the same nursery in Zeeland, Mich. since 2017 using traditional shoot tip cutting procedures and later sterile shoot-tip tissue culture and found to reproduce plants that are identical and exhibit all the characteristics of the original plant in successive generations.SUMMARY OF THE INVENTION
Dianthus ‘Pinky Promise’ has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in the environment including: growing temperature, available sunlight, nutrition, water, etc. without a change in the genotype of the plant.
The closest comparison plants to the new plant known to the inventor include: ‘Paint the Town Magenta’ U.S. Plant Pat. No. 29,222, ‘Paint the Town Fuchsia’ U.S. Plant Pat. No. 28,636, KAHORI® ‘Pink’ (not patented), ‘Zing Rose’ (not patented).
‘Paint the Town Magenta’ has a similar habit and size, but the foliage is more glaucous, and the flowers are vibrant magenta-pink without the lighter center eye. ‘Paint the Town Fuchsia’ has a similar habit and size, but the foliage is more glaucous and the flowers are more fuchsia-colored. KAHORI® ‘Pink’ has smaller size and less dense habit, the flowers are more pinkish near white styles, and the individual petals are narrower with less overlapping. ‘Zing Rose’ is less compact, has smaller flowers, the flowers are more magenta, the petals have less overlapping, and there is a thin darker red eye.
The female parent, 11-265-1, has a more open habit, smaller flowers and wider leaves that were more green. The male parent, 12-60-1, had larger flowers, longer narrower leaves and more compact habit.
Dianthus ‘Pinky Promise’ is distinct from its parents and all other Dianthus known to the applicant in the following combined traits:
- 1. Single flowers with five overlapping petals forming a full rounded face;
- 2. Petals have a moderately serrated apex;
- 3. Petal color is a soft fuchsia-pink with slightly darker veins near the center;
- 4. Numerous flowers per plant on dense, heavily-branched, upright stems;
- 5. Flowering period in a strong flush in late spring following vernalization nearly completely covering dome of the plant;
- 6. Compact, dense and moderately spreading habit with lightly-glaucous, foliage.
The photographs of ‘Pinky Promise’ are of a two-year-old plant grown in a full-sun trial garden in Zeeland, Mich. showing the overall appearance of the plant including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, direction, or reflection.
The following detailed description of ‘Pinky Promise’ is based on observations of two-year-old plants in a full-sun trial garden at a nursery in Zeeland, Mich. with supplemental watering, light additions of fertilizer and free of other plant growth regulators. All color usage is in accordance with the 2015 edition of The Royal Horticultural Colour Chart except where common dictionary terms are used.
