plant named ‘Ember Glow’

Abstract

A new and distinct cultivar of Helichrysum plant named ‘Ember Glow’, characterized by its mounding plant habit; freely branching growth habit, bushy growth form; numerous inflorescences positioned above the foliar plane; red-colored involucral bracts that become light red to orange red with development; and good postproduction longevity and garden performance.

Description

Botanical designation: Helichrysum×amorginum.

Cultivar denomination: ‘EMBER GLOW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Helichrysum plant, botanically known as Helichrysum×amorginum and hereinafter referred to by the name ‘Ember Glow’.

The new Helichrysum plant is a product of a controlled breeding program conducted by the Inventor in Derby, Chaddesden, United Kingdom. The objective of the breeding program is to create new mounding Helichrysum plants with unique and attractive inflorescence color.

The new Helichrysum plant originated from a cross-pollination in March, 1999 in Derby, Chaddesden, United Kingdom, of Helichrysum×amorginum ‘Blorub’, disclosed in U.S. Plant patent application Ser. No. 11/177,992 (abandoned), as the female, or seed, parent with an unnamed proprietary selection of Helichrysum×amorginum, not patented, as the male, or pollen, parent. The new Helichrysum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Derby, Chaddesden, United Kingdom in March, 2000.

Asexual reproduction of the new Helichrysum plant by vegetative cuttings in a controlled environment in Derby, Chaddesden, United Kingdom since July, 2000, has shown that the unique features of this new Helichrysum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Helichrysum have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ember Glow’. These characteristics in combination distinguish ‘Ember Glow’ as a new and distinct Helichrysum plant:

• • 1. Mounding plant habit.
  • 2. Freely branching growth habit, bushy growth form.
  • 3. Numerous inflorescences positioned above the foliar plane.
  • 4. Red-colored involucral bracts that become light red to orange red with development.
  • 5. Good postproduction longevity and garden performance.

Plants of the new Helichrysum differ primarily from plants of the female parent, ‘Blorub’, primarily in involucral bract color as plants of ‘Blorub’ have red-colored involucral bracts.

Plants of the new Helichrysum differ primarily from plants of the male parent selection primarily in involucral bract color as plants of the male parent selection have yellow-colored involucral bracts.

Plants of the new Helichrysum can also be compared to plants of the Helichrysum×amorginum ‘Pink Sapphire’, disclosed in U.S. Plant Pat. No. 20,476. In side-by-side comparisons conducted in Derby, Chaddesden, United Kingdom, plants of the new Helichrysum differed primarily from plants of ‘Pink Sapphire’ in involucral bract color as plants of ‘Pink Sapphire’ had pink-colored involucral bracts.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Helichrysum plant.

The photograph on the first sheet comprises a top perspective view of typical flowering plants of ‘Ember Glow’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Ember Glow’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in ground beds in an outdoor nursery in Bressingham, Norfolk, United Kingdom and under commercial practices.
