Abstract

A new and unique cultivar of perennial plant Carnation or Pinks, Dianthus plant named ‘Fire and Ice’ with long-blooming, fragrant, single flowers, with overlapping petals of deep raspberry with irregular fine flecks of pink and up to two larger pink spots. The petals have a margin of light pink becoming nearly white. Dianthus ‘Fire and Ice’ is tolerant of high temperatures and resists center die-out.

Description

Botanical denomination: Dianthus hybrid.

Cultivar designation: ‘Fire and Ice’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of Dianthus or Pinks from the genus Dianthus and given the cultivar name ‘Fire and Ice’ previously known internally by the breeder code DIA070720. The new plant was the result of an intentional cross in May of 2007 by Kevin A. Hurd between Dianthus ‘Strawberry Sorbet’ U.S. Plant Pat. No. 18,338 as the female or seed parent and ‘Cranberry Ice’ U.S. Plant Pat. No. 18,342) as the male or pollen parent. The new hybrid was first isolated from trials at a nursery in Zeeland, Mich. during the summer of 2008. Dianthus ‘Fire and Ice’ 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.

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. The new plant is distinct from its parents and all other Dianthus known to the applicant in the following combined traits:

- 1. Flat, single, overlapping petals of deep raspberry with irregular fine flecks of pink and up to two larger pink spots,
- 2. Petals having a margin of light pink becoming nearly white,
- 3. High heat tolerance with no vernalization required for flower production,
- 4. Floriferous, vigorous and excellent habit, and
- 5. Compact, fine-textured, blue-green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new invention 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 a close-up of the flower.

DETAILED DESCRIPTION OF THE PLANT

The following detailed description of the new plant is based on observations of one-year old plants in greenhouse-grown container 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.
