plant named ‘Leilani’

Abstract

A new and distinct Echinacea plant named ‘Leilani’ characterized by large yellow inflorescences, a short habit with good branching, a narrow, upright habit, strong stems, and excellent vigor.

Description

Botanical denomination: Echinacea spp.

Variety designation: ‘Leilani’.

The present invention relates to a new and distinct cultivar of Echinacea and given the cultivar name ‘Leilani’. Echinacea is in the family Asteraceae. This new cultivar is a fourth generation seeding originating from a planned breeding program using Echinacea paradoxa (an unpatented plant) as the seed parent in the original cross and Echinacea purpurea ‘Ruby Giant’ (an unpatented plant) as the pollen parent. The exact parents of this selection are unknown, unnamed, proprietary plants.

Compared to Echinacea ‘Mac ‘n’ Cheese’ (U.S. Plant Pat. No. 19,464), the most similar plant on the market, the new variety is more vigorous, has more crowns, larger inflorescences, and the flowers are more yellow, less gold, in color.

Compared to Echinacea ‘Now Cheesier’ (U.S. Plant Pat. No. 23,059), the new variety is shorter with flowers that are more yellow, less gold, in color.

Compared to Echinacea Harvest Moon™ (‘Matthew Saul’ U.S. Plant Pat. No. 17,652), the new variety has longer and wider ray florets and a shorter habit.

This new Echinacea cultivar is distinguished by:

• • 1. large yellow inflorescences,
  • 2. a short habit with good branching,
  • 3. narrow, upright habit,
  • 4. strong stems, 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, 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.
