plant named ‘ECH391’

Abstract

A new and distinct cultivar of Echinacea plant named ‘ECH391’, characterized by its upright plant habit; moderately vigorous growth habit; freely branching habit; strong flowering stems; numerous large single-type inflorescences with pale yellow-colored ray florets that are red purple towards the base and dark purple-colored receptacle spines; and good garden performance.

Description

Botanical designation: Echinacea purpurea.

Cultivar denomination: ‘ECH391’.

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 ‘ECH391’.

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 branching and relatively compact Echinacea plants with unique and attractive ray floret coloration.

The new Echinacea plant originated from a cross-pollination made by the Inventor in July, 2014 in Zuidwolde, The Netherlands of two unnamed seedling selections of Echinacea purpurea, not patented. The new Echinacea plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Zuidwolde, The Netherlands in July, 2016.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since March, 2017 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 ‘ECH391’. These characteristics in combination distinguish ‘ECH391’ 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 single-type inflorescences with pale yellow-colored ray florets that are red purple towards the base and dark purple-colored receptacle spines.
  • 6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the parent selections. Plants of the new Echinacea differ primarily from plants of the parent selections in growth habit as plants of the new Echinacea are more compact and uniform than plants of the parent selections.

Plants of the new Echinacea can be compared to plants of Echinacea purpurea ‘Mistral’, disclosed in U.S. Plant Pat. No. 20,498. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘Mistral’ in the following characteristics:

• • 1. Plants of the new Echinacea are taller than plants of ‘Mistral’.
  • 2. Plants of the new Echinacea and ‘Mistral’ differ in ray floret color as plants of ‘Mistral’ have red purple-colored ray 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 photographs on the second sheet are close-up views of typical inflorescences (upper photograph) and typical leaves (lower photograph) of ‘ECH391’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the summer in 21-cm containers in an outdoor nursery in Zuidwolde, The Netherlands and under cultural practices typically used in commercial Echinacea production.
