plant named ‘Vanilla Cupcake’

Abstract

A new and distinct Echinacea plant named ‘Vanilla Cupcake’ characterized by large inflorescences with white to cream ray florets and light yellow lime disc florets, enlarged disc florets forming an anemone-type inflorescence, ray florets which are held horizontally when young, a short, mounding habit with high stem count, and high vigor.

Description

Botanical denomination: Echinacea hybrid.

Variety designation: ‘Vanilla Cupcake’.

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Vanilla Cupcake’. Echinacea is in the family Asteraceae. The new cultivar is part of a planned breeding program for a series with compact habits and double “anemone”-type inflorescences. The exact parents of this selection are unknown, unnamed, proprietary interspecific hybrids.

Compared to Echinacea ‘White Double Delight’ (U.S. Plant Pat. No. 23,472), the new cultivar has larger inflorescences.

Compared to Echinacea ‘Milkshake’ (U.S. Plant Pat. No. 20,594), the new cultivar has larger inflorescences.

This new Echinacea cultivar is distinguished by:

• • 1. large inflorescences with white to cream ray florets and light yellow lime disc florets,
  • 2. enlarged disc florets forming an anemone-type inflorescence,
  • 3. ray florets which are held horizontally when young,
  • 4. a short, mounding habit with excellent stem count, and
  • 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, was done in Canby, Oreg., and 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.
