USPP33293P2 - Dianthus plant named ‘Paint the Town Red’ - Google Patents

Abstract

A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named ‘Paint the Town Red’ with numerous, single, lightly-spicy fragrant flowers producing a full rounded face. Each flower has five overlapping petals that are deep magenta-red colored without darker red bars in the center. Petals have moderately coarse dentate apices. Flowering season is strong for four weeks beginning in late spring and continues to mid-fall. The habit is compact and dense with glaucous blue-green foliage.

Description

Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Paint the Town Red’.

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

The first non-enabling disclosure of the claimed plant was made by Walters Gardens, Inc. on Dec. 1, 2019 in the form of a website brief description and photograph followed by a short description and photograph in the “Walters Gardens 20-21 Catalog” by Walters Gardens, Inc. The first sales of the claimed plant was on Jun. 29, 2020 by Walters Gardens, Inc. to Walla Walla Nursery Co. Walters Gardens, Inc. obtained the new plant and information about the new plant directly from the inventor. No plants of Dianthus ‘Paint the Town Red’ 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 the new and distinct cultivar of carnation or pinks from the genus Dianthus and given the cultivar name ‘Paint the Town Red’. The new plant was the result of an intentional cross on Jun. 14, 2012 under the direction of the inventor between ‘Neon Star’ U.S. Plant Pat. No. 14,549 as the female or seed parent and ‘Kahori’ (not patented) as the male or pollen parent. The cross was harvested and sown in the fall of 2012. The new hybrid was first selected from trials at a wholesale perennial nursery in Zeeland, Mich. during the summer of 2014 as a single seedling clone and given the breeder code number 12-94-1 later in the evaluation processes. Dianthus ‘Paint the Town Red’ has been asexually propagated at the same nursery in Zeeland, Mich. since 2014 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 ‘Paint the Town Red’ 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.

The closest comparison plants to the new plant known to the inventor include: ‘Paint the Town Magenta’ U.S. Plant Pat. No. 29,922, ‘Paint the Town Fuchsia’ U.S. Plant Pat. No. 28,636, ‘Kahori’ (not patented) and ‘Paint the Town Red’ copending U.S. Plant Patent Application.

‘Paint the Town Magenta’ has a similar habit and foliage but the flowers are slightly smaller and of vibrant magenta-pink. ‘Paint the Town Fuchsia’ has similar habit and foliage, but the flowers are slightly smaller and fuchsia colored with lavender centers. ‘Paint the Town Fancy’ has similar habit and foliage and the flowers are more rosy-fuchsia colored with a larger dark red bar. ‘Neon Star’ (in side by side growing conditions of mature plants) has a larger habit and flowers that are lighter pink with a lighter lavender-pink bar. The male parent, KAHORI®, has smaller habit with more light green foliage and the flowers are more pinkish.

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

• • 1. Single flowers with a five overlapping petals forming a full rounded face;
  • 2. Petals have moderately-coarse dentate apices;
  • 3. Petal color is a deep magenta red;
  • 4. Numerous flowers per plant on heavily branched upright stems;
  • 5. Prolonged flowering period with a strong flush in late spring and continuing to mid- fall;
  • 6. Compact habit and dense, glaucous, blue-green foliage.
