plant named ‘Cleopatra’

Abstract

A new cultivar of hybrid Echinacea, ‘Cleopatra’, characterized by its composite flowers with ray florets that are deep yellow in color and held horizontal, its very strong stems, its short plant height, and its compact plant habit.

Description

Botanical classification: Echinacea hybrid.

Variety denomination: ‘Cleopatra’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Echinacea Plant Named ‘Julia’ (U.S. Plant patent application Ser. No. 13/507,851).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea of hybrid origin and will be referred to hereafter by its cultivar name, ‘Cleopatra’. ‘Cleopatra’ represents a new coneflower, an herbaceous perennial grown for landscape use.

The new cultivar arose from an ongoing breeding program of the Inventor's in Zuidwolde, The Netherlands. The objective of the breeding program is to develop new cultivars of classic cone-type (non-anemone type) Echinacea having horizontal ray florets with unique and strong colors. The new cultivar arose from open pollination of an unnamed plant from the Inventor's breeding, designated as Ec 7001-03, in summer of 2008. The male parent is unknown. ‘Cleopatra’ was selected as single unique plant from the resulting seedlings in July of 2010.

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in Heerhugowaard, The Netherlands in 2008 under the direction of the Inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Cleopatra’ as a unique cultivar of Echinacea.

• • 1. ‘Cleopatra’ exhibits large composite flowers with ray florets that are deep yellow in color.
  • 2. ‘Cleopatra’ exhibits ray florets that are held horizontal.
  • 3. ‘Cleopatra’ is short in height and exhibits a compact plant habit.
  • 4. ‘Cleopatra’ exhibits very strong stems.

The female parent, designated as Ec 7001-03, differs from ‘Cleopatra’ in having a taller plant height and ray florets that are lighter yellow in color. The new cultivar can be most closely compared to the cultivars ‘Sunrise’ (U.S. Plant Pat. No. 16,235), ‘CBG Cone3’ (U.S. Plant Pat. No. 16,636), and ‘Julia’ (U.S. Plant patent Ser. No. 13/507,851). ‘Sunrise’ differs from ‘Cleopatra’ in having ray florets that are lighter yellow in color and in having taller and weaker stems. ‘CBG Cone3’ differs from ‘Cleopatra’ in having ray florets that are yellow-orange in color, held less horizontal and less overlapping, and in having taller stems. ‘Julia’ differs from ‘Cleopatra’ in having ray florets that are orange in color.

BRIEF DESCRIPTION OF THE DRAWING

The photograph in FIG. 1 shows a group of cut stems.

The photograph in FIG. 2 provides a close-up view of inflorescences of ‘Cleopatra’.

The photograph in FIG. 3 provides a close-up view of a leaf of ‘Cleopatra’. The 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.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of one year-old plants of the new cultivar as field grown outdoors in September in Zuidwolde, The Netherlands. Plants were grown under average day temperatures ranging from 12° to 28° C. and average night temperatures of 6° to 16° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
