plant named ‘POST301’

Abstract

A new and distinct cultivar of Echinacea plant named ‘Post301’, characterized by its upright and relatively compact plant habit; moderately vigorous growth habit; freely branching habit; strong flowering stems; numerous large single-type inflorescences with red-colored ray florets and dark red-colored receptacle spines; and good garden performance.

Description

Botanical designation: Echinacea hybrida.

Cultivar denomination: ‘POST301’.

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 ‘Post301’.

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

The new Echinacea plant originated from a cross-pollination in June, 2012 in Zuidwolde, The Netherlands of a proprietary selection of Echinacea hybrida identified as code number 651-01, not patented, as the female, or seed, parent with Echinacea hybrida ‘Purple Emperor’, disclosed in U.S. Plant Pat. No. 24,459, 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 cross-pollination grown in a controlled greenhouse environment in Zuidwolde, The Netherlands in July, 2014.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since December, 2014 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 ‘Post301’. These characteristics in combination distinguish ‘Post301’ as a new and distinct Echinacea plant:

• • 1. Upright and relatively compact plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Strong flowering stems.
  • 5. Numerous large single-type inflorescences with red-colored ray florets and dark red-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 shorter than plants of the female parent selection.
  • 2. Plants of the new Echinacea are not as freely branching as plants of the female parent selection.
  • 3. Plants of the new Echinacea have larger inflorescences than plants of the female parent selection.

Plants of the new Echinacea can be compared to plants of the male parent, ‘Purple Emperor’. Plants of the new Echinacea differ primarily from plants of ‘Purple Emperor’ in the following characteristics:

• • 1. Plants of the new Echinacea are shorter than plants of ‘Purple Emperor’.
  • 2. Plants of the new Echinacea are not as freely branching as plants of ‘Purple Emperor’.
  • 3. Plants of the new Echinacea and ‘Purple Emperor’ differ in ray floret color as ray florets of plants of ‘Purple Emperor’ are purple pink in color.

Plants of the new Echinacea can be compared to plants of Echinacea spp. ‘Tomato Soup’, disclosed in U.S. Plant Pat. No. 19,427. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Echinacea differed primarily from plants of ‘Tomato Soup’ in the following characteristics:

• • 1. Plants of the new Echinacea were shorter than plants of ‘Tomato Soup’.
  • 2. Plants of the new Echinacea were more freely branching than plants of ‘Tomato Soup’.

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 ‘Post301’ grown in ground beds in an outdoor nursery and placed in a 17.5 cm by 22 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 typical leaves (lower photograph) of ‘Post301’.
