plant named ‘Hope’

Abstract

A new cultivar of Dianthus hybrida, ‘Hope’, characterized by its clean, mounded, blue foliage, and its single flowers that are bright fuchsia in color.

Description

Botanical classification: Dianthus hybrida.

Variety denomination: ‘Hope’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dianthus plant, botanically of hybrid origin and known as Dianthus ‘Hope’ and will be referred to hereinafter by its cultivar name, ‘Hope’. The new cultivar represents a new cultivar of cheddar pinks, an herbaceous perennial grown for landscape use.

‘Hope’ was discovered by the Inventors in a container in a nursery in Lewisburg, Tenn. in April of 2007. The new cultivar arose as a chance seedling in a quart container amongst a block of containers of ‘Firewitch’ (not patented) and ‘Frosty Fire’. Although the parentage is unknown, ‘Firewitch’ and ‘Frosty Fire’ are likely parents due to the characteristics of the new cultivar and their proximity.

Asexual reproduction of the new cultivar was first accomplished by one of the Inventors using stem cuttings in June of 2007 in Paw Paw, Mich. Using stem cutting and in vitro propagation, the characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Hope’ as unique from all other varieties of Dianthus known to the Inventors.

• • 1. ‘Hope’ exhibits single flowers that are bright fuchsia in color.
  • 2. ‘Hope’ exhibits clean, mounded, blue foliage.

In comparison to its likely parent plant, ‘Fire Witch’, ‘Hope’ differs in having cleaner, more blue foliage and flowers that are bright fuchsia rather than pink and in blooming later in the season. In comparison to its likely parent plant, ‘Frosty Fire’, ‘Hope’ has similar foliage, however ‘Frosty Fire’ differs from ‘Hope’ in having double flowers that are more red in color and in flowering later in the season. ‘Hope’ can also compared to the Dianthus cultivar ‘Devon Xera’ (U.S. Plant Pat. No. 14,895). ‘Hope’ has similar foliage to ‘Devon Xera’, however ‘Devon Xera’ differs from ‘Hope’ in having flowers that are crimson red in color with a darker red center eye and in producing less flowers.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Dianthus. The photographs in the figures were taken of a plant about six months in age as grown in a garden for two months from a 1-liter container.

FIG. 1 provides a view of the plant habit of ‘Hope’ in bloom and

FIG. 2 provides a close-up view of the flowers of ‘Hope’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Dianthus.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of plants about six months in age as grown in a garden in Michigan for two months from a 1-liter container. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
