USPP33471P2 - Echinacea plant named ‘TNECHSDL’ - Google Patents

Abstract

A new and distinct Echinacea plant named ‘TNECHSDL’ characterized by enlarged disc florets forming an anemone-type inflorescence, bright yellow ray florets and yellow disc florets, ray florets which are held horizontally to drooping, a short, upright habit with excellent stem count, and excellent vigor.

Description

Botanical denomination: Echinacea spp.

Variety designation: ‘TNECHSDL’.

Trademark designation: Sunny Days Lemon™.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘TNECHSDL’. Echinacea is in the family Asteraceae. The new cultivar is part of a planned breeding program for a landscape series with compact habits and profuse, double 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 ‘TNECHCMY’, U.S. Plant Pat. No. 31,142, the new cultivar is taller and more upright.

This new Echinacea cultivar is uniquely distinguished by:

• • 1. enlarged disc florets forming an anemone-type inflorescence,
  • 2. bright yellow ray florets and yellow disc florets,
  • 3. ray florets which are held mostly horizontally to drooping,
  • 4. a medium, upright habit with excellent stem count, and
  • 5. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (cuttings 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 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 asexually 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.
