plant named ‘TNECHKW’

Abstract

A new and distinct Echinacea plant named ‘TNECHKW’ characterized by an amazing number of large inflorescences starting in the first season, very long bloom time with excellent rebloom, a very upright, very compact habit, white ray florets surrounding green cones, ray florets held horizontally when young then dropping slightly, strong upright stems, and excellent vigor.

Description

Botanical denomination: Echinacea spp.

Variety designation: ‘TNECHKW’.

Trademark designation: Kismet™ White.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘TNECHKW’. Echinacea is in the family Asteraceae. The new cultivar is part of a planned breeding program for a container and edging series with compact habits and profuse inflorescences. The exact parents of this selection are unknown, unnamed, proprietary interspecific hybrids bred from Echinacea paradoxa, Echinacea purpurea, and Echinacea tennesseensis.

Compared to Echinacea ‘Mediation White’ (U.S. Plant Pat. No. 27,015), the new cultivar is shorter.

Compared to Echinacea purpurea ‘Purity’ (U.S. Plant Pat. No. 19,441), the new cultivar is shorter, with narrower leaves, more crowns from the base, produces more flowers earlier, and has flowers with orange cones rather than green.

This new Echinacea cultivar is uniquely distinguished by:

• • 1. an amazing number of large inflorescences starting in the first season,
  • 2. very long bloom time with excellent rebloom,
  • 3. very upright, very compact habit,
  • 4. white ray florets surrounding green cones,
  • 5. ray florets held horizontally when young then dropping slightly,
  • 6. strong upright stems, and
  • 7. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture using shoot tips). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and 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.
