Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Raspberry Ruffles’.


The present invention relates to the new and distinct cultivar of carnation or pinks from the genus Dianthus and given the cultivar name ‘Raspberry Ruffles’. The new plant was the result of an intentional cross on May 14, 2012 under the direction of the inventor between Dianthus ‘WP Passion’ U.S. Plant Pat. No. 20,440 as the female or seed parent and ‘Valda Isolde’ U.S. Plant Pat. No. 13,915 (known by the tradename Fancy Knickers) as the male or pollen parent. The cross was harvested and sown on Jul. 2, 2012. The new hybrid was first isolated from trials at a wholesale perennial nursery in Zeeland, Mich. during the summer of 2013 as a single seedling clone and given the breeder number 12-64-3 later in the evaluation processes. Dianthus ‘Raspberry Ruffles’ has been asexually propagated at the same nursery in Zeeland, Mich. since 2013 using traditional shoot tip cutting procedures and found to reproduce plants that are identical and exhibit all the characteristics of the original plant.

No plants of Dianthus ‘Raspberry Ruffles’ have been sold in this country, or anywhere in the world, under this or any name or tradename, 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.


Dianthus ‘Raspberry Ruffles’ has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment including: growing temperature, available sunlight, nutrients, water, etc. without a change in the genotype of the plant.

Compared with the new plant, the female parent ‘WP Passion’ has red flowers without bar or band, that have less than one-third the number of petals per flower and the petals have an entire to sinuate margin compared to the crenate to dentate margins of ‘Raspberry Ruffles’. The male parent, ‘Fancy Knickers’, has white flower petals with a magenta base compared with the raspberry-colored petals with lighter margin of the new plant with up to 100 more petals per flower. The nearest comparison cultivars known to the inventor are: ‘Cherry Vanilla’ U.S. Plant Pat. No. 29,684 and ‘Coral Reef’ U.S. Plant Pat. No. 19,660. The flower petals of ‘Coral Reef’ are primarily a lighter reddish coral color and a wide white margin with fewer petals than the new plant. Compared with ‘Cherry Vanilla’, a sister sibling, the ground flower petal color is a deeper red and the margin is broader and more contrasting. Compared with ‘Cranberry Cocktail’ U.S. Plant Pat. No. 28,603 the comparison has solid hot magenta pink flowers with about half the number of petals per flower and without a lighter margin on the petals.

Dianthus ‘Raspberry Ruffles’ is distinct from its parents and all other Dianthus known to the applicant in the following combined traits:

    • 1. Fully-double flowers opening up with petal counts per flower about 105.
    • 2. Petals having a raspberry coloration with thin margin beginning light pink and becoming white.
    • 3. Petal margin irregularly toothed.
    • 4. Typically two flowers per stiff, upright peduncle.
    • 5. Large flowers producing a lightly-sweet spicy fragrance.
    • 6. Flower near top of clump, vigorous, with compact habit and finely-textured blue-green foliage.


The photographs of the new invention are of a two-year-old plant grown in full-sun trial garden and demonstrate 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.

FIG. 1 shows the habit of the plant in mid-season flowering.

FIG. 2 shows a close-up of the flowers and bud.


The following detailed description of the new plant is based on observations of two-year-old plants in greenhouse-grown containers in addition to two-year-old plants in 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.
