Echinacea purpurea plant named ‘Mars’

Abstract

A new and distinct Echinacea purpurea plant named ‘Mars’ characterized by red purple, medium-sized flowers; large, ball-like disc; lime green centers when disc florets are unopened; well branched habit; lovely fragrance; and good vigor.

Description

Botanical denomination: Echinacea purpurea.

Variety designation: ‘Mars’.

The present invention relates to a new and distinct cultivar of Echinacea purpurea and given the cultivar name ‘Mars’. Echinacea is in the family Asteraceae. This new cultivar originated as a seedling from an open pollinated cross between Echinacea ‘Ruby Giant’, an unpatented plant, as the seed parent and an unknown pollen parent.

This new Echinacea purpurea cultivar is distinguished by:

• • 1. Red purple, medium-sized flowers.
  • 2. Large, ball-like disc.
  • 3. Lime green centers when disc florets are unopened.
  • 4. Well branched habit.
  • 5. Lovely fragrance.
  • 6. 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

COMPARISONS TO SIMILAR ECHINACEA

Compared to Echinacea purpurea ‘Ruby Giant’, an unpatented plant, the new variety has smaller, brighter red purple flowers, more flowers, and fewer petal layers. The overall plant habit is smaller. The petals of this new variety reflex back slightly with maturity.

Compared to Echinacea purpurea ‘Green Eyes’ (U.S. Plant Pat. No. 17,172) the flowers of this new cultivar are smaller, brighter colored and the petal reflex back slightly with maturity. The disc of the new variety become much larger with maturity.
