Description

Botanical designation: Echinacea hybrida.

Cultivar denomination: ‘MINBEL252’.

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 ‘Minbel252’.

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 July, 2011 in Zuidwolde, The Netherlands of Echinacea hybrida ‘Southern Belle’, disclosed in U.S. Plant Pat. No. 23,493, as the female, or seed, parent with a proprietary selection of Echinacea hybrida identified code number 808-25, not patented, 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 June, 2012.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Zuidwolde, The Netherlands since July, 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 ‘Minbel252’. These characteristics in combination distinguish ‘Minbel252’ as a new and distinct Echinacea plant:

    • 1. Upright and relatively compact plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Strong flowering stems.
    • 5. Numerous large anemone-centered inflorescences with red purple-colored florets.
    • 6. Good garden performance.

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

    • 1. Plants of the new Echinacea are shorter than plants of ‘Southern Belle’.
    • 2. Plants of the new Echinacea have stronger flowering stems than plants of ‘Southern Belle’.
    • 3. Ray florets of plants of the new Echinacea are lighter red purple in color than ray florets of plants of ‘Southern Belle’.

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

    • 1. Plants of the new Echinacea are shorter than plants of the male parent selection.
    • 2. Ray florets of plants of the new Echinacea are darker red purple in color than ray florets of plants of the male parent selection.

Plants of the new Echinacea can be compared to plants of Echinacea purpurea ‘Butterfly Kisses’, disclosed in U.S. Plant Pat. No. 24,458. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Echinacea differed primarily from plants of ‘Butterfly Kisses’ in the following characteristics:

    • 1. Plants of the new Echinacea were taller than plants of ‘Butterfly Kisses’.
    • 2. Plants of the new Echinacea have lighter red purple-colored florets than plants of ‘Butterfly Kisses’.

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 ‘Minbel252’ 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 ‘Minbel252’.

 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 32° C. and night temperatures ranged from 8° C. to 20° C. Plants were eight months old when the photographs and description were taken.
