Description

Botanical designation: Echinacea hybrida.

Cultivar denomination: ‘IFECSSGOLD’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Innoflora Plant Breeding B.V. of Heerhugowaard, The Netherlands on Nov. 24, 2022, application number 2022/2656. Foreign priority is not claimed to this application.

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 ‘IFECSSGOLD’.

The new Echinacea plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to develop new vigorous and freely flowering Echinacea plants with large inflorescences with unique and attractive ray floret coloration.

The new Echinacea plant originated from an open-pollination in July, 2018 in Heerhugowaard, The Netherlands of a proprietary selection of Echinacea hybrida identified as code number 009-17-K019-02, not patented, as the female, or seed, parent with an unknown proprietary selection of Echinacea hybrida, as the male, or pollen, parent. The new Echinacea plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled greenhouse environment in Heerhugowaard, The Netherlands in August, 2019.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Heerhugowaard, The Netherlands since September, 2019 has shown that the unique features of this new Echinacea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Echinacea have 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 ‘IFECSSGOLD’. These characteristics in combination distinguish ‘IFECSSGOLD’ as a new and distinct Echinacea plant:

• • 1. Relatively compact and upright plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Strong flowering stems.
  • 5. Numerous single-type inflorescences with dark yellow-colored ray florets and bright yellow-colored receptacle spines.
  • 6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the female parent selection. Plants of the new Echinacea differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Echinacea are taller than plants of the female parent selection.
  • 2. Inflorescences of plants of the new Echinacea have about five whorls of ray florets whereas inflorescences of plants of the female parent selection have about four whorls of ray florets.
  • 3. Ray florets of plants of the new Echinacea are dark yellow in color whereas ray florets of plants of the female parent selection are white in color.

Plants of the new Echinacea can be compared to plants of Echinacea spp. ‘TNECHCMY’, disclosed in U.S. Plant Pat. No. 31,142. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘TNECHCMY’ in the following characteristics:

• • 1. Plants of the new Echinacea are stronger than plants of ‘TNECHCMY’.
  • 2. Plants of the new Echinacea have single-type inflorescences whereas plants of ‘TNECHCMY’ have anemone-type inflorescences.

Plants of the new Echinacea can also be compared to plants of Echinacea x hybrida ‘Balsomemyim’, disclosed in U.S. Plant Pat. No. 30,116. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘Balsomemyim’ in the following characteristics:

• • 1. Plants of the new Echinacea are more compact than plants of ‘Balsomemyim’.
  • 2. Inflorescences of plants of the new Echinacea have about five whorls of ray florets whereas inflorescences of plants of ‘Balsomemyim’ have two whorls of ray florets.
