Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Dianthus caryophyllus cultivar Wesdiwit.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of potted Carnation plant, botanically known as Dianthus caryophyllus and hereinafter referred to by the name ‘Wesdiwit’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in 's-Gravenzande, The Netherlands. The objective of the breeding program is to create new potted Carnation cultivars having compact plant habit, continuous flowering, and attractive flower coloration.

The new Carnation originated from a cross-pollination made by the Inventor in 's-Gravenzande, The Netherlands, of two unidentified proprietary seedling selections of Dianthus caryophyllus, not patented. The new Carnation was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in 's-Gravenzande, The Netherlands in May, 1999. The selection of this plant was based on its compact plant habit and attractive flower coloration.

Asexual reproduction of the new Carnation by cuttings propagated in a controlled environment in 's-Gravenzande, The Netherlands, since the summer of 1999, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Wesdiwit has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wesdiwit’. These characteristics in combination distinguish ‘Wesdiwit’ as a new and distinct cultivar:

1. Compact, upright and rounded plant habit.

2. Freely basal branching habit.

3. Strong lateral branches.

4. Dark green-colored foliage.

5. Continuous flowering habit during the flowering season.

6. White-colored flowers.

Compared to plants of the female parent, plants of the new Carnation are more compact, more vigorous and have stronger lateral branches. Compared to plants of the male parent, plants of the new Carnation are more vigorous and differ in flower color.

Plants of the new Carnation can be compared to plants of the cultivar Diogenes, not patented. In side-by-side comparisons conducted in 's-Gravenzande, The Netherlands, plants of the new Carnation and the cultivar Diogenes differed in the following characteristics:

1. Plants of the new Carnation were more compact than plants of the cultivar Diogenes.

2. Flowers of plants of the new Carnation were white in color whereas flowers of plants of the cultivar Diogenes were pink in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Carnation, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 Carnation.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Wesdiwit’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of flowers and leaves of a typical plant of ‘Wesdiwit’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in 's-Gravenzande, The Netherlands during the summer in a glass-covered greenhouse. During the production of the plants, day temperatures ranged from 20 to 25° C. and night temperatures ranged from 18 to 20° C. Rooted young plants were planted in 10-cm containers and pinched once. The photographs and the description were taken about five months after planting.
