Carnation plant named ‘Hilprot’

Abstract

A new and distinct cultivar of Carnation plant named ‘Hilprot’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; freely branching habit; freely flowering habit; large purple-colored double flowers with light pink-colored margins that are positioned above and beyond the foliar plane on strong peduncles; and good garden performance.

Description

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘HILPROT’.

BACKGROUND OF THE INVENTION

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

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new potted Carnation plants that have uniform plant habit and numerous attractive flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in June, 2009 of a proprietary selection of Dianthus caryophyllus identified as code number 2318160782, not patented, as the female, or seed, parent with Dianthus caryophyllus ‘Margarita’, disclosed in U.S. Plant Pat. No. 17,335, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in September, 2010.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since October, 2010 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Hilprot’. These characteristics in combination distinguish ‘Hilprot’ as a new and distinct Carnation plant:

• • 1. Upright, outwardly spreading and uniformly mounded plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Large purple-colored double flowers with light pink-colored margins that are positioned above and beyond the foliar plane on strong peduncles.
  • 5. Good garden performance.

Plants of the new Carnation differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Carnation are more outwardly spreading than and not as upright as plants of the female parent selection.
  • 2. Plants of the new Carnation have longer lateral branches then plants of the female parent selection.
  • 3. Plants of the new Carnation flower a few days earlier than plants of the female parent selection.
  • 4. Flower petals of plants of the new Carnation are more rounded than flower petals of plants of the female parent selection.

Plants of the new Carnation differ from plants of the male parent, ‘Margarita’, in the following characteristics:

• • 1. Plants of the new Carnation have broader leaves than plants of ‘Margarita’.
  • 2. Flowers of plants of the new Carnation have more petals per flower than flowers of plants of ‘Margarita’.
  • 3. Flower petals of plants of the new Carnation are more rounded than flowers petals of plants of ‘Margarita’.
  • 4. Plants of the new Carnation and ‘Margarita’ differ slightly in flower color.

Plants of the new Carnation can be compared to plants of Dianthus caryophyllus ‘Hilbreye’, disclosed in U.S. Plant Pat. No. 24,340. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Carnation differed from plants of ‘Hilbreye’ in the following characteristics:

• • 1. Plants of the new Carnation were more outwardly spreading than and not as upright as plants of ‘Hilbreye’.
  • 2. Plants of the new Carnation had smaller flowers than plants of ‘Hilbreye’.
  • 3. Plants of the new Carnation and ‘Hilbreye’ differed slightly in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Hilprot’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the late winter and early spring in 12-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial potted Carnation production. During the production of the plants, day and night temperatures averaged 12° C. and light levels averaged 7 klux. Plants were pinched one time five weeks after planting. Plants used for the description were 20 weeks old and plants used for the photograph were 25 weeks old.
