Description

Botanical designation: Echinacea purpurea.

Cultivar denomination: ‘ECHCHER298’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name ‘Echcher298’.

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

The new Echinacea plant originated from an open-pollination in June, 2012 in Zuidwolde, The Netherlands of Echinacea purpurea ‘Meringue’, disclosed in U.S. Plant Pat. No. 20,537, as the female, or seed, parent with an unknown selection of Echinacea purpurea 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 Zuidwolde, The Netherlands in July, 2013.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since December, 2013 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 ‘Echcher298’. These characteristics in combination distinguish ‘Echcher298’ as a new and distinct Echinacea plant:

    • 1. Upright plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Strong flowering stems.
    • 5. Numerous large anemone-centered inflorescences with pale yellow green to white and light pink-colored florets.
    • 6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the female parent, ‘Meringue’. Plants of the new Echinacea differ from plants of ‘Meringue’ in the following characteristics:

    • 1. Plants of the new Echinacea are taller than plants of ‘Meringue’.
    • 2. Plants of the new Echinacea flower later than plants of ‘Meringue’.
    • 3. Plants of the new Echinacea and ‘Meringue’ differ in floret color as plants of ‘Meringue’ have yellow green-colored florets.

Plants of the new Echinacea can be compared to plants of Echinacea purpurea ‘Coconut Lime’, disclosed in U.S. Plant Pat. No. 18,617. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Echinacea differed primarily from plants of ‘Coconut Lime’ in the following characteristics:

    • 1. Plants of the new Echinacea were not as freely branching as plants of ‘Coconut Lime’.
    • 2. Plants of the new Echinacea had larger inflorescences than plants of ‘Coconut Lime’.
    • 3. Plants of the new Echinacea and ‘Coconut Lime’ differed in floret color as plants of ‘Coconut Lime’ had white and yellow green-colored florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Echinacea plant 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 Echinacea plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Echcher298’ grown in ground beds in an outdoor nursery and placed in a 21 cm container for the photograph.

The photographs on the second sheet are close-up views of a typical inflorescence (upper photograph) and the upper surface of a typical leaf (lower photograph) of ‘Echcher298’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in ground beds in an outdoor nursery in Zuidwolde, The Netherlands and under cultural practices typically used in commercial Echinacea production. During the production of the plants, day temperatures ranged from 18° C. to 30° C. and night temperatures ranged from 8° C. to 18° C. Plants were eight months old when the photographs and description were taken. 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.
