USPP23036P3 - Echinacea plant named ‘Secret Romance’ - Google Patents

Abstract

A new and distinct Echinacea plant named ‘Secret Romance’ characterized by lavender pink ray florets, enlarged deep pink disc florets forming an anemone-type inflorescence, a dwarf habit with good branching and strong stems, and excellent vigor.

Description

Botanical denomination: Echinacea spp.

Variety designation: ‘Secret Romance’.

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Secret Romance’. 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 has a much more compact habit and lighter pink inflorescences.

Compared to Echinacea ‘Coral Reef’ (U.S. Plant Pat. No. 21,888), the new cultivar is much shorter and has lavender pink ray florets rather than dark orange to coral.

Compared to Echinacea ‘Pink Double Delight’ (U.S. Plant Pat. No. 18,803), the new cultivar has more crowns, and a more upright habit, with larger inflorescences that are a different shade of pink.

This new Echinacea cultivar is distinguished by:

• • 1. lavender pink ray florets,
  • 2. enlarged deep pink disc florets forming an anemone-type inflorescence,
  • 3. a dwarf habit with good branching and strong stems, 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.
