Variety denomination: ‘BLU481’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2020/2457 filed on Oct. 7, 2020, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea of hybrid origin and will be referred to hereafter by its cultivar name, ‘BLU481’. ‘BLU481’ represents a new cultivar of coneflower, an herbaceous perennial grown for landscape use.

The new cultivar arose from an ongoing breeding program by the Inventor in Zuidwolde, The Netherlands with the objective of selecting new cultivars of Echinacea with strong plant habits, unique inflorescence colors and enlarged disc florets. The new cultivar was selected as a unique seedling in a trial field by the Inventor in July of 2018. The trial field had been planted with seed collected from numerous cultivars and proprietary Echinacea seedlings from the Inventor's breeding program. The parentage of ‘BLU481’ is therefore unknown.

Asexual propagation of the new cultivar was first accomplished by tissue culture using meristematic tissue in Heerhugowaard, The Netherlands in March of 2019 under the direction of the Inventor. Asexual propagation by tissue culture has determined that the characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘BLU481’ as a unique cultivar of Echinacea.

• • 1. ‘BLU481’ exhibits inflorescences with ray florets that are deep red-purple in color.
  • 2. ‘BLU481’ exhibits conspicuous inflorescences with disc florets that are deep red-purple in color and changing to a slightly lighter color towards the tip.

The new cultivar can be most closely compared to the cultivars ‘Drop352’ (U.S. Plant Pat. No. 30,378) and ‘Pink Double Delight’ (U.S. Plant Pat. No. 18,803). ‘Drop352’ and ‘Pink Double Delight’ are both similar to ‘BLU481’ in inflorescence shape. ‘Drop352’ differs from ‘BLU481’ in having ray florets that are yellow-green in color, disc florets that are yellow-orange and fading to yellow-green in color, and inflorescences that are larger in size. ‘Pink Double Delight’ differs from ‘BLU481’ in having ray florets that are red-purple to grey-purple in color, and disc florets that red-purple in color the entire floret (not changing color towards the tip) and in producing more inflorescences per plant.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant less than one year prior to the effective filing date would have been obtained from a direct or indirect disclosure from the Inventor under 35 U.S.C. 102(b)(1). Disclosures include but may not be limited to website listing by AB cultivars.
