plant named ‘Electric Red’

Abstract

A new and unique plant cultivar of perennial carnation or pinks, Dianthus plant named ‘Electric Red’ with numerous, medium-sized, semi-double petals of deep red without barring or markings. Compact plant produces highly-glaucous, silvery-colored, linear foliage with vigorous compact habit. Dianthus ‘Electric Red’ is tolerant of high temperatures and resists center die-out.

Description

Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Electric Red’.

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 ‘Electric Red’. The new plant was the result of an intentional cross on Jun. 26, 2013 by the inventor between the unreleased proprietary hybrid assigned the breeder code 11-167-01 (not patented) as the female or seed parent and the unreleased proprietary hybrid assigned the breeder code 11-283-1 (not patented) as the male or pollen parent. Seeds of the cross were harvested in the summer of 2013. The new hybrid was first isolated from trials at a wholesale perennial nursery in Zeeland, Mich. during the summer of 2014 as a single seedling and given the breeder number 13-50-1 during the remaining evaluation processes. Dianthus ‘Electric Red’ has been asexually propagated at the same nursery in Zeeland, Mich. since 2014 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 ‘Electric Red’ have been sold in this country, or anywhere in the world, 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.

SUMMARY OF THE INVENTION

The present invention 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.

Direct comparison of the new plant with the female parent and male parent are not possible as those plants were not maintained. Comparing the new plant with Dianthus ‘Red Beauty’ U.S. Plant Pat. No. 20,301, the comparison plant is smaller in habit and flower size with only five to seven petals per flower. Compared with the new plant, ‘Red Dwarf’ U.S. Plant Pat. No. 14,437 has two-tone red petals. The grandparents of the new plant include: ‘Devon Xera’ U.S. Plant Pat. No. 14,895, ‘Pomegranate Kiss’ U.S. Plant Pat. No. 21,895 and ‘Devon Flavia’ U.S. Plant Pat. No. 15,903. Compared with the new plant averaging twenty-seven petals, ‘Devon Xera’ has five petals, and ‘Devon Flavia’ has 15 to 20 petals per flower. ‘Devon Xera’ is taller in flower than the new plant and the flowers petals of ‘Devon Xera’ have a darker purple-red band while the flower petals of the new plant are lacking the darker band.

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

• • 1. semi-double flowers of vibrant, rich deep, red petals.
  • 2. Petals having moderately serrated apex.
  • 3. Plants producing many flower stems with excellent flower coverage over the entire mound in mid-spring with over 600 flowers on two-year old plants.
  • 4. Floriferous, vigorous, with compact habit and finely-textured silvery-colored foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of Dianthus ‘Electric Red’ 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 greenhouse-grown containers at a nursery in Zeeland, Mich. with light shade, supplemental watering, light additions of fertilizer and free of other 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.
