Botanical designation: Xerochrysum bracteatum.
Cultivar denomination: ‘BONXE 1669’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Xerochrysum plant, botanically known as Xerochrysum bracteatum, and hereinafter referred to by the name ‘Bonxe 1669’.
The new Xerochrysum plant is a product of a planned breeding program conducted by the Inventors in Yellow Rock, New South Wales, Australia. The objective of the breeding program is to create and develop new upright Xerochrysum cultivars with upright and uniformly mounded plant habit, freely flowering habit and attractive inflorescences and inflorescence buds.
The new Xerochrysum plant originated from a cross-pollination by the Inventors on Sep. 2, 2015 of a proprietary selection of Xerochrysum bracteatum identified as code number 14-6, not patented, as the female, or seed, parent with a proprietary selection of Xerochrysum bracteatum identified as code number 14-60, not patented, as the male, or pollen, parent. The new Xerochrysum plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia on Aug. 1, 2016.
Asexual reproduction of the new Xerochrysum plant by terminal cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since August, 2016, has shown that the unique features of this new Xerochrysum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONPlants of the new Xerochrysum have not been observed under all possible combinations of environmental and cultural 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 ‘Bonxe 1669’. These characteristics in combination distinguish ‘Bonxe 1669’ as a new and distinct Xerochrysum plant:
-
- 1. Upright, mounding and uniform plant habit.
- 2. Vigorous growth habit.
- 3. Freely flowering habit.
- 4. Relatively large inflorescences with purplish red and pale purple bi-colored involucral bracts.
- 5. Strong peduncles that hold the inflorescences above the foliar plane.
In side-by-side comparisons, plants of the new Xerochrysum differ primarily from plants of the female parent selection in the involucral bract color as involucral bracts of plants of the new Xerochrysum are purplish red and pale purple bi-colored whereas involucral bracts of plants of the female parent selection are creamy white in color.
In side-by-side comparisons, plants of the new Xerochrysum differ primarily from plants of the male parent selection in the involucral bract color as involucral bracts of plants of the new Xerochrysum are purplish red and pale purple bi-colored whereas involucral bracts of plants of the male parent selection are pink in color.
Plants of the new Xerochrysum can be compared to plants of the Bracteantha bracteata ‘Bonxero 148’, disclosed in U.S. Plant Pat. No. 30,398. In side-by-side comparisons, plants of the new Xerochrysum differ primarily from plants of ‘Bonxero 148’ in the following characteristics:
-
- 1. Plants of the new Xerochrysum are broader than plants of ‘Bonxero 148’.
- 2. Plants of the new Xerochrysum are more freely branching than plants of ‘Bonxero 148’.
- 3. Plants of the new Xerochrysum have smaller leaves than plants of ‘Bonxero 148’.
- 4. Plants of the new Xerochrysum are more freely flowering than plants of ‘Bonxero 148’.
- 5. Involucral bracts of plants of the new Xerochrysum are purplish red and pale purple bi-colored whereas involucral bracts of plants of ‘Bonxero 148’ are bright yellow in color.
- 6. Plants of the new Xerochrysum have shorter peduncles than plants of ‘Bonxero 148’.
The accompanying photographs illustrate the overall appearance of the new Xerochrysum plant. These photographs show 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 Xerochrysum plant.

The aforementioned photographs and following observations and measurements describe plants grown during the early summer in 24-cm container in an outdoor nursery in Higashiomi, Shiga, Japan and under conditions and practices which approximate those generally used in commercial Xerochrysum production. During the production of the plants, day temperatures averaged 23° C. and night averaged 13° C. Measurements and numerical values represent averages for typical flowering plants. Plants were four months old when the photographs were taken and five months old when the detailed description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
