plant named ‘DWGBO20’

- Overdevest Nurseries

A new and distinct cultivar of Echinacea purpurea plant named ‘DWGBO20’ is disclosed, characterized by large, fully double chrysanthemum-like inflorescences composed of ray florets arranged consistently in a dome. Plants are bushy and sturdy with an upright habit. Free and continuous flowering begins in June and continues through September. Echinacea is a popular genus, typically used as container plants or landscape plants.

Description

Latin name of the genus and species: Echinacea purpurea.

Variety denomination: ‘DWGBO20’.

BACKGROUND OF THE INVENTION

The new variety, Echinacea ‘DWGBO20’, is the product of a planned breeding program by the inventor. The crossing resulting in the new variety was made during July of 2020 at a commercial nursery in Bridgeton, NJ. The seed parent is an unnamed, unpatented proprietary variety of Echinacea purpurea. The pollen parent is a different unnamed, unpatented proprietary variety of Echinacea purpurea. The discovery was made during July of 2021, in Bridgeton, NJ, at the same commercial nursery.

Asexual reproduction of the new variety ‘DWGBO20’ was first performed Bridgeton, NJ, at the same commercial nursery, by divisions in April of 2023. Plants from this reproduction of Echinacea ‘DWGBO20’ have shown that the unique features of this variety are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The variety ‘DWGBO20’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘DWGBO20’. These characteristics in combination distinguish ‘DWGBO20’ as a new and distinct Echinacea variety:

    • 1. Large, fully double (Chrysanthemum-like) inflorescences.
    • 2. Free and continuous flowering.
    • 3. Multiple broad petals (ray florets) arranged & displayed consistently in a dome.
    • 4. Bushy, sturdy, upright habit.

PARENTAL COMPARISON

Plants of the new variety ‘DWGBO20’ are similar to plants of the seed parent in most horticultural characteristics. However, plants of the new variety ‘DWGBO20’ differ in the following:

    • 1. Inflorescences of the new variety are fully double; inflorescences of the seed parent are semi-double.
    • 2. Plants of the new variety are bushier and less open than plants of the seed parent.

Plants of the new variety ‘DWGBO20’ are similar to plants of the pollen parent in most horticultural characteristics. However, plants of the new variety ‘DWGBO20’ differ in the following:

    • 1. Inflorescences of the new variety are fully double; inflorescences of the pollen parent are semi-double.
    • 2. Plants of the new variety are shorter than plants of the pollen parent.
    • 3. Plants of the new variety are more floriferous than plants of the pollen parent.

COMMERCIAL COMPARISON

The new variety ‘DWGBO20’ can be compared to the commercial variety Echinacea ‘Lovely Lolly’ (unpatented). Plants of the new variety ‘DWGBO20’ differ in the following:

    • 1. Plants of the new variety are about 80 cm in height, while plants of this comparator are about 50 cm in height.
    • 2. Inflorescence shape of the new variety is a flattened dome; inflorescence shape of this comparator is spherical.
    • 3. Inflorescences of the new variety are lighter and brighter in color.
    • 4. Inflorescences of the new variety are wider than inflorescences of this comparator.

The new variety ‘DWGBO20’ can be compared to the patented Echinacea ‘Razzmatazz’, U.S. Plant Pat. No. 13,894. Plants of the new variety ‘DWGBO20’ differ in the following:

    • 1. Inflorescence shape of the new variety is a flattened dome; inflorescence shape of this comparator is anemone.
    • 2. Plants of the new variety produce more inflorescences than plants of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living variety, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of new Echinacea ‘DWGBO20’. Plants were grown in Bridgeton, NJ.

FIG. 1 illustrates in full color a plant of Echinacea ‘DWGBO20’ grown in the ground at approximately 1 year old.

FIG. 2 illustrates in full color a close-up view of the inflorescences of Echinacea ‘DWGBO20’ at maturity.
