Bracteantha plant named ‘Flobrafla’

Abstract

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

Description

Botanical designation: Bracteantha bracteata.

Cultivar denomination: ‘Flobrafla’.

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 ‘Flobrafla’.

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 a cross-pollination by the Inventor in January, 1999, of a proprietary selection of Bracteantha bracteata identified as code number 97-004, not patented, as the female, or seed, parent with an unknown selection of Bracteantha bracteata, 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 cross-pollination in a controlled environment in Redland Bay, Queensland, Australia in September, 2000.

Asexual reproduction of the new Bracteantha by terminal cuttings in a controlled environment in Redland Bay, Queensland, Australia since May, 2001, 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 ‘Flobrafla’ and distinguish the new Bracteantha as a new and distinct cultivar:

• • 1. Compact and bushy growth habit.
  • 2. Upright and rounded plant form.
  • 3. Freely-flowering habit.
  • 4. Bronzed orange and golden yellow bi-colored involucral bracts and golden yellow-colored 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 more compact and denser than plants of the female parent selection.
  • 2. Plants of the new Bracteantha and the female parent selection differed in involucral bract coloration as plants of the female plant had orange-colored involucral bracts.

Plants of the new Bracteantha can also be compared to plants of the cultivar Redbragol, disclosed in U.S. Plant Pat. No. 12,988. 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 Redbragol in the following characteristics:

• • 1. Inflorescences of plants of the new Bracteantha were flat and not as cupped as inflorescences of plants of the cultivar Redbragol.
  • 2. Plants of the new Bracteantha were more freely flowering than plants of the cultivar Redbragol.
  • 3. Inflorescences of plants of the new Bracteantha had fewer involucral bracts and disc florets than inflorescences of plants of the cultivar Redbragol.
  • 4. Plants of the new Bracteantha and the cultivar Redbragol differed in involucral bract coloration as plants of the cultivar Redbragol had yellow-colored involucral bracts.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Bracteantha.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Flobrafla’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Flobrafla’. Plants used in the photographs were grown in 14-cm containers and were about three months old.

DETAILED BOTANICAL DESCRIPTION

The 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 22 to 35° C. and night temperatures ranging from 15 to 20° C. Rooted liners of the new Bracteantha were planted in 250-mm containers and grown for about six months. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
