plant named ‘Green Queen’

A new and distinct Echinacea purpurea cultivar named ‘Green Queen’ is disclosed, characterized by chartreuse/green flowers, with slight pink blush on the lower ray florets, strong peduncles, and producing many flowers per plant. The new variety is an Echinacea, suitable for outdoor and container gardens as well as cut flower production.

Description

Latin name of the genus and species: Echinacea purpurea

Variety denomination: ‘GREEN QUEEN’.

BACKGROUND OF THE INVENTION

The new variety was discovered, by the inventor, as a naturally occurring whole plant mutation in a grouping of the parent variety, Echinacea purpurea ‘Green Envy,’ formerly the subject of a U.S. Plant patent application, Ser. No. 11/513,465. It was discovered by the inventor in the summer of 2005.

Asexual reproduction of the new cultivar ‘Green Queen’ by tissue culture using standard micropropagation techniques with terminal shoots, was first performed in a commercial laboratory in Oregon, beginning in the Spring of 2006 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Green Queen’ 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 ‘Green Queen’ These characteristics in combination distinguish ‘Green Queen’ as a new and distinct Echinacea cultivar:

    • 1. The new variety has a clear green/chartreuse flower.
    • 2. The new variety produces more flowers per plant than similar Echinaceas.
    • 3. The new variety produces a very strong, straight peduncle, suitable cut flower purposes.
    • 4. The plant habit of the new variety is distinctively upright.

PARENTAL COMPARISON

Plants of the new cultivar ‘Green Queen’ are similar to plants of the parent variety, Echinacea purpurea ‘Green Envy’ in most horticultural characteristics; however, ‘Green Queen’ produces more flowers per plant than the parent variety. Additionally, ‘Green Queen’ produces a significantly more stable flower color. Whereas ‘Green Envy’ has shown to produce almost completely pink flowers out of tissue culture, ‘Green Queen’ is consistently chartreuse/green, with slight pink coloration near the base of ray florets.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘Green Queen’ are most similar to plants of the commercial variety, Echinacea purpurea ‘Green Jewel’ U.S. Plant Pat. No. 18,678 in most horticultural characteristics; however, ‘Green Queen’ produces more flowers per plant than ‘Green Jewel.’ Additionally, ‘Green Queen’ is a significantly smaller and more compact plant, approximately half the height and width of ‘Green Jewel.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical flowers, peduncles and leaves of ‘Green Queen’ grown outdoors in the New York state. The plant shown is approximately 7 months old. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
