plant named ‘Maui Sunshine’

Abstract

A new and distinct Echinacea plant named ‘Maui Sunshine’ characterized by large, bright yellow flowers with multiple ray florets, ray florets held perpendicular to the stem, well-branched flower stalks, a medium tall habit, and excellent vigor.

Description

Botanical denomination: Echinacea sp.

Variety designation: ‘Maui Sunshine’.

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Maui Sunshine’. Echinacea is in the family Asteraceae. This new cultivar originated as a fourth generation seedling from a planned breeding program using the unpatented parents Echinacea paradoxa and Echinacea purpurea ‘Ruby Giant’ for the initial cross. The exact parents of this selection are unnamed proprietary, unreleased plants.

Compared to Echinacea ‘Ruby Giant’, an unpatented plant and the original seed parent in the breeding line, the new variety has yellow rather than red purple flowers.

Compared to Echinacea paradoxa, an unpatented plant and the original pollen parent in the breeding line, the new variety is shorter, with ray florets held on the horizontal rather than drooping and green cones with yellow orange bracts rather than brown cones with brown bracts.

Compared to Echinacea ‘Mac ‘n’ Cheese’, U.S. Plant Pat. No. 19,464, the new variety is taller with yellow flowers rather than yellow orange flowers.

This new Echinacea cultivar is distinguished by:

• • 1. large, bright yellow flowers with multiple ray florets
  • 2. ray florets held perpendicular to the stem
  • 3. well-branched flower stalks
  • 4. medium tall habit
  • 5. 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.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Echinacea cultivar based on observations of 18-month-old specimens growing in the ground in the field in full sun in the trial bed under typical outdoor conditions in Canby, Oreg.
