Abstract

A new and distinct cultivar of Echinacea plant named ‘Twilight’, characterized by its upright and columnar plant habit; freely branching growth habit; large inflorescences with red purple-colored ray florets and dark purple-tipped receptacle spines; relatively early flowering habit; fragrant inflorescences; and good garden performance.

Description

Botanical designation: Echinacea hybrida.

Cultivar denomination: ‘Twilight’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea hybrida, and hereinafter referred to by the name ‘Twilight’.

The new Echinacea is a product of a planned breeding program conducted by the Inventor in Dahlonega, Ga. The objective of the breeding program is to develop new fragrant Echinacea cultivars with early flowering responses and unique ray floret coloration.

The new Echinacea originated from a cross-pollination made by the Inventor in July, 2002 of the Echinacea purpurea cultivar White Swan, not patented, as the female, or seed, parent with an unnamed selection of Echinacea purpurea×Echinacea paradoxa, not patented, as the male, or pollen, parent. The new Echinacea was discovered and selected as a single flowering plant by the Inventor in a controlled environment in Dahlonega, Ga. in June, 2003 from the resultant progeny of the stated cross-pollination. The new Echinacea was selected on the basis of its unique ray floret coloration.

Asexual reproduction of the new Echinacea by tissue culture was first conducted in Atlanta, Ga. in September, 2003. Since then, asexual reproduction by tissue culture has shown that the unique features of this new Echinacea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Twilight 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 ‘Twilight’. These characteristics in combination distinguish ‘Twilight’ as a new and distinct Echinacea:

- 1. Upright and columnar plant habit.
- 2. Freely branching growth habit.
- 3. Large inflorescences with red purple-colored ray florets and dark purple-tipped receptacle spines.
- 4. Relatively early flowering habit.
- 5. Fragrant inflorescences.
- 6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the female parent, the cultivar White Swan. In side-by-side comparisons conducted in Dahlonega, Ga., plants of the new Echinacea differed from plants of the cultivar White Swan in the following characteristics:

- 1. Plants of the new Echinacea were more compact than plants of the cultivar White Swan.
- 2. Plants of the new Echinacea flowered earlier than plants of the cultivar White Swan.
- 3. Plants of the new Echinacea and the cultivar White Swan differed in ray floret coloration as plants of the cultivar White Swan had white-colored ray florets.

Plants of the new Echinacea can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Dahlonega, Ga., plants of the new Echinacea differed from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Echinacea were shorter than plants of the male parent selection.
- 2. Plants of the new Echinacea were more freely flowering than plants of the male parent selection.
- 3. Plants of the new Echinacea and the male parent selection differed in ray floret and receptacle spine coloration as plants of the male parent selection had magenta-colored ray florets and golden yellow-colored receptacle spines.

Plants of the new Echinacea can be compared to plants of the Echinacea cultivar Magnus, not patented. In side-by-side comparisons conducted in Dahlonega, Ga., plants of the new Echinacea differed from plants of the cultivar Magnus in the following characteristics:

- 1. Plants of the new Echinacea were more compact than plants of the cultivar Magnus.
- 2. Plants of the new Echinacea and the cultivar Magnus differed in ray floret coloration as plants of the cultivar Magnus had magenta pink-colored ray florets.
- 3. Plants of the new Echinacea and the cultivar Magnus differed in receptacle spine coloration as plants of the cultivar Magnus had golden orange-colored receptacle spines.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Echinacea.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Twilight’.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Twilight’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Dahlonega, Ga., in an outdoor nursery under full sun conditions during the summer. When the plants were about one year old, the photographs, observations and measurements were taken. Plants used for the detailed description were grown in one-gallon containers. During the year-long production of the plants, day temperatures ranged from −2° C. to 32° C. and night temperatures ranged from −15° C. to 21° C. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
