USPP23018P3 - Echinacea plant named ‘Secret Passion’ - Google Patents

Abstract

A new and distinct Echinacea plant named ‘Secret Passion’ characterized by enlarged disc florets forming an anemone-type inflorescence, warm pink ray florets contrasting strongly with the deep flamingo pink disc florets, a low habit with good branching, and excellent vigor.

Description

Botanical denomination: Echinacea spp.

Variety designation: ‘Secret Passion’.

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Secret Passion’. Echinacea is in the family Asteraceae. This new cultivar is a third generation seeding originating from a planned breeding program using Echinacea purpurea ‘Razzmatazz’ (U.S. Plant Pat. No. 13,894) as the seed parent in the original cross and unnamed proprietary, unreleased interspecific hybrids for the pollen parent. The exact parents of this selection are unknown, unnamed, proprietary plants.

Compared to Echinacea purpurea ‘Razzmatazz’ (U.S. Plant Pat. No. 13,894), the seed parent in the original breeding line, the new variety is shorter with more crowns, and with larger, darker pink inflorescences.

Compared to Echinacea ‘Pink Double Delight’ (U.S. Plant Pat. No. 18,803), the new cultivar has more crowns, inflorescences with darker pink discs and that have a stronger contrast between the ray and disk florets.

This new Echinacea cultivar is distinguished by:

• • 1. enlarged disc florets forming an anemone-type inflorescence,
  • 2. warm pink ray florets contrasting strongly with the deep flamingo pink disc florets,
  • 3. a low habit with good branching, and
  • 4. excellent 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 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.
