Abstract

A new and distinct cultivar of Helenium plant named ‘Helbro’, characterized by its upright and somewhat outwardly spreading plant habit; freely basal branching growth habit; freely flowering habit; large upright-facing inflorescences with yellow and red bi-colored ray florets; and strong and erect peduncles that tolerate wind and rain.

Description

Botanical classification/cultivar designation: Helenium hybrida cultivar Helbro.
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 ‘Helbro’.
The new Helenium was discovered as a chance seedling of two unidentified selections of Helenium hybrida, not patented. The new Helenium was discovered and selected by the Inventor in 1996 as a single flowering plant in a controlled environment in Worcester, United Kingdom.
Asexual reproduction of the new Helenium by cuttings was first conducted in Worcester, United Kingdom in June, 1996. Since then, asexual reproduction by divisions has shown that the unique features of this new Helenium are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Helbro has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Helbro’. These characteristics in combination distinguish ‘Helbro’ as a new and distinct Helenium:
1. Upright and somewhat outwardly spreading plant habit.
2. Freely basal branching growth habit.
3. Freely flowering habit.
4. Large upright-facing inflorescences with yellow and red bi-colored ray florets.
5. Strong and erect peduncles that tolerate wind and rain.
Plants of the new Helenium differ primarily from plants of the parent selections in ray and disc floret coloration.
Plants of the new Helenium can be compared to plants of the Helenium cultivar Coppelia, not patented. In side-by-side comparisons conducted in Worcester, United Kingdom, plants of the new Helenium differed from plants of the cultivar Coppelia in the following characteristics:
1. Plants of the new Helenium were larger than plants of the cultivar Coppelia.
2. Plants of the new Helenium had larger leaves and inflorescences than plants of the cultivar Coppelia.
3. Plants of the new Helenium were more freely flowering than plants of the cultivar Coppelia.
4. Plants of the new Helenium and the cultivar Coppelia differed in ray floret coloration as plants of the cultivar Coppelia had red-colored ray florets.
5. Plants of the new Helenium had stronger, longer and thicker peduncles than plants of the cultivar Coppelia.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Helenium showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Helenium. The photograph comprises a close-up view of typical inflorescences and leaves of typical flowering plants of ‘Helbro’ grown in an outdoor nursery.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations and measurements describe plants grown in Bressingham, Diss, Norfolk, United Kingdom, under outdoor field conditions which closely approximate commercial production conditions. During the production of the plants, day temperatures ranged from 5 to 28° C. and night temperatures ranged from −8 to 15° C. Plants used for the photograph and description were grown for two growing seasons in 5-liter containers.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
