plant named ‘Balsaluglo’

Abstract

A new and distinct cultivar of Helenium plant named ‘Balsaluglo’, characterized by its medium golden-yellow and greyed-red colored inflorescences, medium green-colored foliage, and moderately vigorous, and compact-upright growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Helenium autumnale.

Variety denomination: ‘Balsaluglo’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Helenium plant botanically known as Helenium autumnale and hereinafter referred to by the cultivar name ‘Balsaluglo’.

The new cultivar originated in a controlled breeding program in Hem, The Netherlands during August 2013. The objective of the breeding program was the development of Helenium cultivars having increased branching and a compact growth habit.

The new Helenium cultivar is the result of open-pollination within an insect-cage environment of six proprietary Helenium autumnale breeding selections not coded, not patented, characterized by varying shades of bronze-yellow to red, medium green-colored foliage, and moderately vigorous, upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during July 2014 in a controlled environment in Hem, The Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings since July 2014 in Hem, The Netherlands and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balsaluglo’ as a new and distinct cultivar of Helenium plant:

• • 1. Medium golden-yellow and greyed-red colored inflorescences;
  • 2. Medium green-colored foliage;
  • 3. Moderately vigorous, and compact-upright growth habit.

Plants of the new cultivar differ from plants of the parents primarily in having a more compact growth habit.

Of the many commercially available Helenium cultivars, the most similar in comparison to the new cultivar is MARIACHI ‘Fuego’, U.S. Plant Pat. No. 25,977. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Fuego’ in at least the following characteristics:

• • 1. Plants of the new cultivar have fewer ray florets than plants of ‘Fuego’;
  • 2. Plants of the new cultivar have a ray floret color and pattern different from plants of ‘Fuego’; and
  • 3. Plants of the new cultivar have smaller diameter inflorescences than plants of ‘Fuego’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balsaluglo’. The plants were approximately five months old. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. followed by 3 weeks in an open-sided polyhouse in West Chicago, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balsaluglo’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in August 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately six-month old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. followed by 7 weeks in an open-sided polyhouse in West Chicago, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant. Greenhouse temperatures were maintained at approximately 65° F. to 70° F. (18.3° C. to 21.1° C.) during the day and approximately 55° F. to 60° F. (12.8° C. to 15.6° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
