USPP18814P2 - Echinacea purpurea plant named ‘Merlot’ - Google Patents

Abstract

A new and distinct Echinacea purpurea plant named ‘Merlot’ characterized by its upright, well branched habit, large red purple flowers, multiple flowering stems, and unique deep maroon stems.

Description

Botanical denomination: Echinacea purpurea.

Variety designation: ‘Merlot’.

The present invention relates to a new and distinct cultivar of Echinacea purpurea and given the cultivar name ‘Merlot’. Echinacea is in the family Asteraceae. This new cultivar originated as a seedling from an open pollinated cross between unknown parents.

This new Echinacea purpurea cultivar is distinguished by:

• • 1. Large red purple flowers
  • 2. Dark maroon flowering stems
  • 3. Well branched upright habit with multiple flowering stems
  • 4. Fragrance
  • 5. Good 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.

BRIEF DESCRIPTION OF THE DRAWING

The photograph shows a 17 months old Echinacea purpurea ‘Merlot’ growing in the ground in full sun in the field in late summer in Canby, Oreg.

COMPARISONS TO SIMILAR ECHINACEA

Compared to Echinacea purpurea ‘Ruby Giant’, an unpatented plant, the new variety has larger flowers and dark maroon rather than green flowering stems.

Compared to Echinacea purpurea ‘Fatal Attraction’ (U.S. Plant Patent applied for), the new variety has slightly downwardly turned petals with maturity rather than upwardly turned. The new variety is larger growing and has larger flowers. Both have dark flowering stems.
