plant named ‘HILMOOOJOY’

Abstract

A new and distinct cultivar of Echinacea plant named ‘Hilmooojoy’, characterized by its upright plant habit; moderately vigorous growth habit; strong and healthy roots; dark green-colored leaves; strong flowering stems; numerous large inflorescences with orange-colored ray florets; and good garden performance.

Description

Botanical designation: Echinacea purpurea.

Cultivar denomination: ‘HILMOOOJOY’.

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 ‘Hilmooojoy’.

The new Echinacea plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to develop new strong and freely flowering Echinacea plants with attractive ray and disc floret coloration.

The new Echinacea plant originated from an open-pollination in June, 2009 in De Kwakel, The Netherlands of a proprietary selection of Echinacea purpurea identified as code designation T 12058 A, not patented, as the female, or seed, parent with an unknown selection of Echinacea purpurea 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 open-pollination grown in a controlled greenhouse environment in De Kwakel, The Netherlands in July, 2010.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in De Kwakel, The Netherlands since September, 2010 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 ‘Hilmooojoy’. These characteristics in combination distinguish ‘Hilmooojoy’ as a new and distinct Echinacea plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Strong and healthy roots.
  • 4. Dark green-colored leaves.
  • 5. Strong flowering stems.
  • 6. Numerous large inflorescences with orange-colored ray florets.
  • 7. Good garden performance.

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

• • 1. Plants of the new Echinacea are more compact than plants of the female parent selection.
  • 2. Plants of the new Echinacea have darker green-colored leaves than plants of the female parent selection.
  • 3. Plants of the new Echinacea have smaller inflorescences than plants of the female parent selection.
  • 4. Ray florets of plants of the new Echinacea are lighter orange in color than ray florets of plants of the female parent selection.

Plants of the new Echinacea can be compared to plants of Echinacea hybrida ‘Orange273’, disclosed in U.S. Plant patent application Ser. No. 14/756,660. In side-by-side comparisons conducted in De Kwakel, The Netherlands, plants of the new Echinacea differed primarily from plants of ‘Orange273’ in the following characteristics:

• • 1. Plants of the new Echinacea were taller than plants of ‘Orange273’.
  • 2. Plants of the new Echinacea were more uniform than plants of ‘Orange273’.
  • 3. Plants of the new Echinacea had smaller inflorescences than plants of ‘Orange273’.
  • 4. Ray florets of plants of the new Echinacea were lighter orange in color than ray florets of plants of ‘Orange273’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates 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 photograph 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 is a side perspective view of a typical flowering plant of ‘Hilmooojoy’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring and early summer in 17-cm containers in a glass-covered greenhouse and “finished” in an outdoor nursery in De Kwakel, The Netherlands under cultural practices typically used in commercial Echinacea production. During the production of the plants, day temperatures ranged from 12° C. to 20° C. and night temperatures ranged from 7° C. to 15° C. Plants used for the photograph and description were 20 weeks old.
