Echinacea purpurea plant named ‘Sparkler’

Abstract

A new and distinct cultivar of Echinacea purpurea plant named ‘Sparkler’ characterized by its distinctive leaves with mottled variegation.

Description

Botanical denomination: Echinacea purpurea.

Variety designation: ‘Sparkler’.

The present invention relates to a new and distinct cultivar of Echinacea purpurea and given the cultivar name ‘Sparkler’. Echinacea is in the family Asteraceae. This new cultivar originated as a whole plant mutation in tissue culture of Echinacea purpurea ‘Ruby Giant’ (an unpatented plant) in Canby, Oreg.

To the breeder's knowledge, this new cultivar is unique. It is the only known variegated Echinacea purpurea that is commercially available.

This new Echinacea purpurea cultivar is distinguished by:

• • 1. Mottled leaf variegation.
  • 2. Semi dwarf habit.
  • 3. Lovely fragrance.
  • 4. Rose pink “flowers” with orange centers.
  • 5. Good vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 shows a one year old Echinacea purpurea ‘Sparkler’ growing in a 3-gallon pot in the greenhouse in the August in Canby, Oreg.

FIG. 2 shows a one year old planting growing in the ground in full sun in the show gardens.

COMPARISONS TO SIMILAR ECHINACEA

Compared to Echinacea purpurea ‘Ruby Giant’, an unpatented plant and the parent, the new cultivar is shorter with mottled variegation on leaves. The ray florets of the new cultivar are a lighter red purple in color.

Compared to Echinacea purpurea ‘Prairie Frost’, an unpatented plant, the new cultivar has mottled leaf variegation rather than edged variegation.
