Echinacea plant named ‘CBG Cone 2’

Abstract

A new cultivar of hybrid Echinacea, ‘CBG Cone 2’, characterized by its compact and dwarf growth habit, its sturdy stems, its horizontally held blooms with medium pink florets surrounding yellow-brown cones, its long blooming habit, its ease of propagation, its vigorous growth habit, and its hardiness in U.S.D.A. Zones 4 to 9.

Description

Botanical classification: Echinacea hybrid.

Variety denomination: ‘CBG Cone 2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of hybrid Echinacea and will be referred to hereafter by its cultivar name, ‘CBG Cone 2’. ‘CBG Cone 2’ represents a new purple coneflower, an herbaceous perennial grown for landscape use.

The new cultivar, ‘CBG Cone 2’, is a selection that arose from an on going breeding program conducted by the inventor in Glencoe, Ill. with the goal of developing new cultivars of Echinacea with desirable garden performance combined with attractive foliage and flowers. ‘CBG Cone 2’ arose from a controlled cross between unnamed plants of the female parent Echinacea tennesseensis×purpurea and the male parent Echinacea angustifolia×tennesseesis. ‘CBG Cone 2’ was selected as unique in July of 2002 for its compact dwarf habit, its dense foliage held on strong stems and for its long blooming habit with blooms that have medium pink ray florets surrounding yellow-brown cones.

Asexual reproduction of the new cultivar was first accomplished by division in June of 2003 followed by in vitro propagation in 2004 by the inventor in Glencoe, Ill. 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 ‘CBG Cone 2’ as a unique cultivar of Echinacea.

• • 1. ‘CBG Cone 2’ exhibits sturdy, well-branched stems and dense foliage resulting in a compact growth habit.
  • 2. ‘CBG Cone 2’ exhibits a dwarf plant habit, reaching a height of 45 to 50 cm (18 to 20 inches).
  • 3. ‘CBG Cone 2’ is long blooming, blooming heavily from mid July to mid August with a few blooms remaining in color in September.
  • 4. ‘CBG Cone 2’ exhibits well formed, horizontally held blooms with ray florets that are medium pink in color surrounding yellow-brown colored cones.
  • 5. ‘CBG Cone 2’ is readily propagated by tissue culture and has a vigorous grower.
  • 6. ‘CBG Cone 2’ is reliably hardy in U.S.D.A. Zones 4 to 9.

The new Echinacea is unique in comparison to other cultivars and species of Echinacea known to the inventor. The cultivar, Echinacea ‘Kim's Knee High’ (U.S. Plant Pat. No. 12,242) is similar in that it has a dwarf plant habit, however ‘Kim's Knee High’ differs in having blooms that have ray florets that are pinkish red in color and cones that are reddish brown in color.

‘CBG Cone 2’ can be compared to the species of its parent hybrids. ‘CBG Cone 2’ differs from Echinacea purpurea in having shorter stems, more basal branching, basal foliage that is more linear in shape and more pubescent, and ray florets that are shorter and held consistently horizontal, c differs from Echinacea tennesseensis in having more pubescent stems and leaves, and ray florets that are held horizontal; the ray florets of E. tennesseensis are curved upwards at a 90° angle from horizontal.
