Bracteantha plant named ‘Flobragbi’

Abstract

A new and distinct cultivar of Bracteantha named ‘Flobragbi’, characterized by its compact and bushy growth habit; upright, outwardly spreading and rounded plant form; freely-flowering habit; golden yellow-colored involucral bracts and disc florets; and short and strong peduncles that hold inflorescences above the foliage.

Description

Botanical classification/cultivar designation: Bracteantha bracteata cultivar Flobragbi.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bracteantha plant, botanically known as Bracteantha bracteata and referred to by the name ‘Flobragbi’.

The new Bracteantha is a product of a planned breeding program conducted by the Inventor in Redland Bay, Queensland, Australia. The objective of the program is to create and develop new compact Bracteantha cultivars with numerous inflorescences, attractive involucral bract coloration and long-lasting inflorescences.

The new Bracteantha originated from an open-pollination by the Inventor in September, 1997, of a proprietary selection of Bracteantha bracteata identified as code number 95-035, not patented, as the female, or seed, parent with an unknown selection of Bracteantha bracteata, not patented, as the male, or pollen, parent. The new Bracteantha was discovered and selected by the Inventor as a plant within the progeny of the stated open-pollination in a controlled environment in Redland Bay, Queensland, Australia in December, 1998.

Asexual reproduction of the new Bracteantha by terminal cuttings in a controlled environment in Redland Bay, Queensland, Australia since December, 1998, has shown that the unique features of this new Bracteantha are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Bracteantha 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 characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Flobragbi’ and distinguish the new Bracteantha as a new and distinct cultivar:

• • 1. Compact and bushy growth habit.
  • 2. Upright, outwardly spreading and rounded plant form.
  • 3. Freely-flowering habit.
  • 4. Golden yellow-colored involucral bracts and disc florets.
  • 5. Short and strong peduncles that hold inflorescences above the foliage.

Plants of the new Bracteantha can be compared to plants of the female parent selection. In side-by-side comparisons conducted by the Inventor in Redland Bay, Queensland, Australia, plants of the new Bracteantha differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Bracteantha were taller than plants of the female parent selection.
  • 2. Plants of the new Bracteantha were more freely flowering than plants of the female parent selection.
  • 3. Plants of the new Bracteantha were denser and bushier than plants of the female parent selection.
  • 4. Plants of the new Bracteantha had narrower leaves than plants of the female parent selection.
  • 5. Plants of the new Bracteantha had smaller inflorescences than plants of the female parent selection.

Plants of the new Bracteantha can also be compared to plants of the cultivar Golden Beauty, not patented. In side-by-side comparisons conducted by the Inventor in Redland Bay, Queensland, Australia, plants of the new Bracteantha differed from plants of the cultivar Golden Beauty in the following characteristics:

• • 1. Plants of the new Bracteantha were more upright than and not as outwardly spreading as plants of the cultivar Golden Beauty.
  • 2. Inflorescences of plants of the new Bracteantha were more rounded than inflorescences of plants of the cultivar Golden Beauty.
  • 3. Inflorescences of plants of the new Bracteantha had more involucral bracts and more disc florets than inflorescences of plants of the cultivar Golden Beauty.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Bracteantha. The photograph comprises a side perspective view of a typical plant of ‘Flobragbi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants grown in Redland Bay, Queensland, Australia during the spring and summer under full sun outdoor conditions, day temperatures ranging from 15 to 30° C. and night temperatures ranging from 10 to 15° C. Rooted liners of the new Bracteantha were planted in three-gallon containers and grown for about six months.
