Dianthus plant named ‘Valda Kitty’

Abstract

A new cultivar of Dianthus named ‘Valda Kitty’ that is characterized by double, crimson red flowers, a compact habit and gray-green foliage. In combination these traits set ‘Valda Kitty’ apart from all other existing varieties of Dianthus known to the inventor.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS

The application for this new invention is co-pending with three other applications entitled ‘Valda Judith’, ‘Valda Louise’ and ‘Valda Isolde’. All are derived from the same program, having the same inventor and filing date as the present application entitled Dianthus ‘Valda Kitty’.

Botanical classification: Dianthus Allwoodii.

Variety denomination: Valda Kitty.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation that is grown for its crimson flowers. The new cultivar is known botanically as Dianthus Allwoodii and will be referred to hereinafter by the cultivar name ‘Valda Kitty’.

‘Valda Kitty’ is the product of a program conducted by the inventor in a cultivated area of Dawlish, Devon, England. The primary focus of the program was to select a variety of flower color mutations from the parent plant ‘Valda Wyatt’ (unpatented).

In 1995, a naturally occuring color sport mutation was found by the inventor on part of a petal of Dianthus ‘Valda Wyatt’ (not patented). The shoots on the lower part of the stem on which the color mutation occured were removed, rooted and grown out into flowers. One or two of the plants produced a whole flower exhibiting the mutated color. This process was repeated until a whole plant was obtained that produced the new color on all flowers.

‘Valda Kitty’ is a hardy perennial grown for its use as a container and landscape plant.

‘Valda Kitty’ was selected for its double, crimson flowers and is characterized by gray-green foliage, compact habit, profuse flowering, free flowering, long flowering and vigorous growth. It is distinguishable from the parent plant ‘Valda Wyatt’ by flower color. The flowers of ‘Valda Wyatt’ are more red (68B) with a incomplete ring (66B) around the base of the petal than those of ‘Valda Kitty’. Asexual reproduction of the new cultivar was first accomplished by the inventor who took cuttings in a cultivated area of Dawlish, Devon, England in 1995. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘Valda Kitty’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions.

1. Dianthus ‘Valda Kitty’ reaches approximately 46 cm. in height and 38 cm. in width at 12 months.

2. Dianthus ‘Valda Kitty’ exhibits bright crimson double flowers.

3. Dianthus ‘Valda Kitty’ exhibits a compact habit.

4. Dianthus ‘Valda Kitty’ exhibits dense gray-green foliage.

5. Dianthus ‘Valda Kitty’ is long flowering, blooming from May to October.

6. Dianthus ‘Valda Kitty’ is hardy to minus 15° Centigrade.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing traits of the new cultivar.

The drawing on sheet 1 is a color copy of an original photograph showing close-up view of ‘Valda Kitty’ and illustrating the flower color, foliage color and dense, compact foliage.

The drawing on sheet 2 is a color copy of an original photograph illustrating the flower color of ‘Valda Kitty’ in comparison to the flower color of the three co-pending varieties. All drawings were made in July of plants grown in 4-inch containers out-of-doors in Encinitas, Calif. All photographs and copies were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography and copying.

BOTANICAL DESCRIPTION OF THE PLANT

The color determinations are in accordance with The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
