USPP22807P3 - Echinacea plant named ‘Hot Lava’ - Google Patents

Abstract

A new and distinct Echinacea plant named ‘Hot Lava’ characterized by large, orange red inflorescences with prominent dark cones, well-branched upright flower stalks, and excellent vigor.

Description

Botanical denomination: Echinacea hybrid.

Variety designation: ‘Hot Lava’.

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

This new Echinacea cultivar is distinguished by:

• • 1. Large, orange red inflorescences with prominent dark cones
  • 2. Well-branched upright flower stalks
  • 3. 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.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 shows the flowers of Echinacea ‘Hot Lava’ on a plant growing in the ground in full sun in the field in late summer in Canby, Oreg.

FIG. 2 shows a habit shot of a one-year-old plant in the summer in the trial bed in Canby, Oreg.

DETAILED PLANT DESCRIPTION
