USPP24392P3 - Echinacea plant named ‘Rosita’ - Google Patents

Abstract

A new and distinct Echinacea plant named ‘Rosita’ characterized by light pink ray florets, numerous, medium to small size inflorescences, a well branched, compact, dwarf habit, and excellent vigor.

Description

Botanical denomination: Echinacea hybrid.

Variety designation: ‘Rosita’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Rosita’. Echinacea is in the family Asteraceae. This new cultivar is part of a planned breeding program to develop dwarf Echinacea hybrids. This cultivar was selected for its compact free flowering habit with light pink inflorescences. The exact parents of this selection are unknown, unnamed, proprietary interspecific hybrid plants.

Compared to Echinacea ‘Little Angel’ (U.S. Plant Pat. No. 21,870), the new cultivar has light pink ray florets rather than white.

Compared to Echinacea ‘Kim's Knee Hi’, an unpatented plant, the new cultivar has lighter pink ray florets and is much shorter.

This new Echinacea cultivar is distinguished by:

• • 1. light pink ray florets,
  • 2. numerous, medium to small size inflorescences,
  • 3. a well branched, compact, dwarf habit, 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.
