Abstract

A new and distinct cultivar of Helenium plant named ‘Sombrero’, characterized by its compact and broadly upright plant habit; moderately vigorous growth habit; freely flowering habit; inflorescences with yellow-colored ray florets; and strong peduncles that hold the inflorescences above the foliar plane.

Description

Botanical designation: Helenium hybrida.
Cultivar denomination: ‘SOMBRERO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Helenium plant, botanically known as Helenium hybrida and hereinafter referred to by the name ‘Sombrero’.
The new Helenium plant is a product of a planned breeding program conducted by the Inventor in Zuidwolde, The Netherlands. The objective of the program is to create and develop new compact Helenium plants with attractive ray and disc colors.
The new Helenium plant is a naturally-occurring branch mutation of Helenium hybrida ‘Salsa’, disclosed in a U.S. Plant Patent application filed concurrently. The new Helenium plant was discovered and selected by the Inventor on a single flowering plant of ‘Salsa’ within a population of plants of ‘Salsa’ in a controlled outdoor nursery environment in Zuidwolde, The Netherlands in 2010.
Asexual reproduction of the new Helenium plant by terminal cuttings in a controlled greenhouse environment in Heerhugowaard, The Netherlands since 2011 has shown that the unique features of this new Helenium plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Helenium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength 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 ‘Sombrero’. These characteristics in combination distinguish ‘Sombrero’ as a new and distinct Helenium plant:
    • 1. Compact and broadly upright plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely flowering habit.
    • 4. Inflorescences with yellow-colored ray florets.
    • 5. Strong peduncles that hold the inflorescences above the foliar plane.
In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Helenium differed from plants of the female parent, ‘Salsa’, primarily in ray floret color as plants of ‘Salsa’ have dark red-colored ray florets with yellow-colored bases giving a “halo” effect around the disc.
Plants of the new Helenium can be compared to plants of Helenium hybrida ‘Kanaria’, not patented. In side-by-side comparisons conducted in Zuidwolde, The Netherlands, plants of the new Helenium differed from plants of ‘Kanaria’ in the following characteristics:
    • 1. Plants of the new Helenium were more compact than plants of ‘Kanaria’.
    • 2. Plants of the new Helenium had smaller inflorescences than plants of ‘Kanaria’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Helenium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 Helenium plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Sombrero’.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Sombrero’.
The photograph on the third sheet is a close-up view of typical leaves of ‘Sombrero’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the autumn in ground beds in an outdoor nursery in Zuidwolde, The Netherlands and under cultural practices typical of commercial Helenium production.

Plants were two years old when the photographs and description were taken.
