plant named ‘Bondre 11100’

Abstract

A new and distinct cultivar of Xerochrysum plant named ‘Bondre 11100’, characterized by its double-type, dark red-colored inflorescences, medium green-colored foliage, and moderately vigorous, compact-mounded growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Xerochrysum bracteatum.

Variety denomination: ‘Bondre 11100’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Xerochrysum plant botanically known as Xerochrysum bracteatum and hereinafter referred to by the cultivar name ‘Bondre 11100’.

The new cultivar originated in a controlled breeding program in Yellow Rock, NSW, Australia during October 2010. The objective of the breeding program was the development of Xerochrysum cultivars with unique flower coloration, and compact, upright-mounded growth habit.

The new Xerochrysum cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Xerochrysum bracteatum breeding selection coded 10-22, not patented, characterized by its double-type, medium red-orange colored inflorescences, medium green-colored foliage, and moderately vigorous, compact-mounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Xerochrysum bracteatum breeding selection coded 10-30, not patented, characterized by its double-type, dark red- colored inflorescences, medium green-colored foliage, and moderately vigorous, upright-mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during March 2011 in a controlled environment in Yellow Rock, NSW, Australia.

Asexual reproduction of the new cultivar by terminal stem cuttings since March 2011 in Yellow Rock, NSW, Australia, Arroyo Grande, Calif., 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 ‘Bondre 11100’ as a new and distinct cultivar of Xerochrysum plant:

• • 1. Double-type, dark red-colored inflorescences;
  • 2. Medium green-colored foliage; and
  • 3. Moderately vigorous, compact-mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a different ray floret color and from plants of the male parent primarily in having longer peduncles.

Of the many commercially available Xerochrysum cultivars, the most similar in comparison to the new cultivar is ‘Helica Dark Red’, not patented. However, in comparison, plants of the new cultivar differ from plants of ‘Helica Dark Red’ in at least the following characteristics:

• • 1. Plants of the new cultivar have larger inflorescences than plants of ‘Helica Dark Red’; and
  • 2. Plants of the new cultivar have more branches than plants of ‘Helica Dark Red’.

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 flower 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 ‘Bondre 11100’. The plants were grown in 4-inch pots for 8 weeks in a greenhouse in West Chicago, Ill. Plants were given one pinch at transplant.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Bondre 11100’.

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, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in December 2013 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 10 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 66° F. to 70° F. (19° C. to 21° C.) during the day and approximately 58° F. to 62° F. (14° C. to 17° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
