Carnation plant named ‘Hilmimi’

Abstract

A new and distinct cultivar of Carnation plant named ‘Hilmimi’, characterized by its uniformly mounding and upright to broadly spreading plant habit; relatively small leaves; freely flowering habit; salmon pink-colored double flowers; and good container performance.

Description

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘HILMIMI’.

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 container plant and hereinafter referred to by the name ‘Hilmimi’.

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 container Carnation plants with numerous double flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in June, 2010 of a proprietary selection of Dianthus caryophyllus identified as code number A76263-02, not patented, as the female, or seed, parent with Dianthus caryophyllus ‘Orapotse’, not patented, 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, 2011.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since October, 2011 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 ‘Hilmimi’. These characteristics in combination distinguish ‘Hilmimi’ as a new and distinct Carnation plant:

• • 1. Uniformly mounding and upright to broadly spreading plant habit.
  • 2. Relatively small leaves.
  • 3. Freely flowering habit.
  • 4. Salmon pink-colored double flowers.
  • 5. Good container 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 freely branching than plants of female parent selection.
  • 2. Plants of the new Carnation have shorter peduncles than plants of the female parent selection.
  • 3. Flower petals of plants of the new Carnation have fewer and fainter dark red-colored stripes than flower petals of plants of the female parent selection.

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

• • 1. Plants of the new Carnation have more petals per flower than plants of ‘Orapotse’.
  • 2. Flower petals of plants of the new Carnation have fewer and fainter dark red-colored stripes than flower petals of plants of ‘Orapotse’.
  • 3. Flower petals of plants of the new Carnation are more praemorse than flower petals of plants of ‘Orapotse’.

Plants of the new Carnation also can be compared to plants of Dianthus caryophyllus disclosed in U.S. Plant patent application Ser. No. 14/120,582. In side-by-side comparisons, plants of the new Carnation differed primarily from plants of ‘Hilluigi’ in the following characteristics:

• • 1. Plants of the new Carnation had smaller flowers than plants of ‘Hilluigi’.
  • 2. Flower petals of plants of the new Carnation were lighter in color than flower petals of plants of ‘Hilluigi’.
  • 3. Flower petals of plants of the new Carnation were more praemorse than flower petals of plants of ‘Hilluigi’.

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 ‘Hilmimi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the winter in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 12° C. to 15° C., night temperatures averaged 12° C. and light levels averaged 7,000 lux. Plants were pinched one time five weeks after planting. Plants used for the photograph and description were twelve weeks old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
