plant named ‘Maraschino’

- Walters Gardens, Inc.

A new and unique cultivar of perennial carnation or pinks plant, named Dianthus ‘Maraschino’ with completely double flowers of overlapping hot cherry-red petals and dark burgundy bands contrasts nicely with the dense, cool, icy, silver-blue compact foliage. ‘Maraschino’ tolerates high temperatures, resists center die-out of the clump and does not require vernalization to flower.

Description

Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Maraschino’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct plant cultivar from the genus Dianthus or commonly referred to as carnation or pinks and given the cultivar name ‘Maraschino’. This new cultivar name has been registered and approved by the International Cultivar Registration Authority for the genus Dianthus as a distinct name. The new plant was the result of an intentional cross in May 19, 2011 by the inventor between Dianthus ‘Devon Xera’ U.S. Plant Pat. No. 14,895 as the female or seed parent and ‘Pomegranate Kiss’ U.S. Plant Pat. No. 21,895 as the male or pollen parent. The seeds from the cross were collected on Jun. 21, 2011. The new hybrid was first isolated from among subsequent trials at a nursery in Zeeland, Mich. during the summer of 2012 as a single seedling and given the breeder number 11-167-01 during the evaluation process. Dianthus ‘Maraschino’ has been asexually propagated at the same nursery in Zeeland, Mich. 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 have been sold, either in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure been made prior to the filing of this application with the exception of that which was within one year of the filing of this application and was derived directly or indirectly from the inventor.

SUMMARY OF THE INVENTION

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with changes in the environment including: growing temperature, available sunlight, nutrients, water, etc. without a change in the genotype of the plant. The new plant is distinct from its parents and all other Dianthus known to the applicant in the following combined traits:

    • 1. Full, completely double, fragrant flowers with overlapping petals of hot cherry-red;
    • 2. Petals having a band of dark burgundy in the adaxial limb center;
    • 3. High heat tolerance with no vernalization required for flower initiation;
    • 4. Floriferous, vigorous, good reblooming and excellent habit; and
    • 5. Compact, fine-textured, cool, icy, silver-blue foliage that remains in good shape through fall.

The nearest comparison cultivar known to the inventor is ‘WP Passion’ U.S. Plant Pat. No. 20,440. Comparing the ‘WP Passion’ with the new plant, ‘Maraschino’ has very similar flower color in the main petal portion, but ‘WP Passion’ lacks the dark burgundy band. ‘WP Passion’ also has smaller flowers without dentate petal apices, and the foliage is more green and less blue than ‘Maraschino’. Compared to the female parent, ‘Devon Xera’, both plants have dark burgundy bands in the petals, but ‘Devon Xera’ has single flowers with only five petals per flower and ‘Maraschino’ is completely double with 20 to 28 petals. Foliage of ‘Devon Xera’ is similar in color and width to the new plant, but slightly longer in ‘Maraschino’; and leaves of ‘Devon Xera’ are entire and ‘Maraschino’ is nearly microscopically serrulate. Compared to the male parent, ‘Pomegranate Kiss’, the new plant has hot cherry-red flower petals, while ‘Pomegranate Kiss’ has an irregular rose pink margin on the petals and is much shorter in overall flowering habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of Dianthus ‘Maraschino’ 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.

DETAILED DESCRIPTION OF THE PLANT

The following detailed description of the new plant is based on observations of 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 any plant growth regulators. All color usage is in accordance with the 2001 edition of The Royal Horticultural Colour Chart except where common dictionary terms are used.
