Abstract

A new and distinct culitvar of Bracteantha bracteata named ‘Florabella Pink’, characterized by its upright, outwardly spreading and rounded plant form; compact plant habit; small lanceolate leaves; pink and white bi-colored involucral bracts and yellow-colored disc florets; and short peduncles that hold inflorescences above the foliage.

Description

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 cultivar name ‘Florabella Pink’.
The new Bracteantha is a product of a planned breeding program conducted by the Inventor in Gapsted, Victoria, Australia. The objective of the program is to create and develop Bracteantha cultivars with a compact growth habit, small leaves, numerous inflorescences, bright involucral bract colors, and short peduncles.
The new Bracteantha originated from a cross by the Inventor of an unidentified yellow involucral bract-colored proprietary selection of Bracteantha bracteata as the female, or seed, parent with an unidentified white involucral bract-colored proprietary 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 in a controlled environment in Gapsted, Victoria, Australia in 1997. The selection of the new Bracteantha was based on its growth habit, leaf size, unique involucral bract-coloration and peduncle length as plants of the new Bracteantha are more compact, have smaller leaves, have pink and white bi-colored involucral bracts, and shorter peduncles than plants of the parent selections.
Asexual reproduction of the new Bracteantha by terminal cuttings taken in a controlled environment in Gapsted, Victoria, Australia, has shown that the unique features of this new Bracteantha are stable and reproduced true to type in successive generations.
The new Bracteantha has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, photoperiod, and water and nutritional status without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Florabella Pink’ and distinguish the new Bracteantha as a new and distinct cultivar:
1. Upright, outwardly spreading and rounded plant form.
2. Compact plant habit.
3. Small lanceolate leaves.
4. Pink and white bi-colored involucral bracts and yellow-colored disc florets.
5. Short peduncles that hold inflorescences above the foliage.
Plants of the new Bracteantha differ from its sibling cultivars, ‘Florabella Gold’, U.S. Plant patent application Ser. No. 09/740,532, and ‘Florabella White’, U.S. Plant patent application Ser. No. 09/740,535 primarily in involucral bract coloration.
The new Bracteantha can be compared to the Bracteantha bracteata cultivar ‘Nullabor Spectrum’, disclosed in U.S. Plant patent application Ser. No. 08/938,583 (abandoned). In side-by-side comparisons conducted by the Inventor in Gapsted, Victoria, Australia, plants of the new Bracteantha are more compact, have shorter and narrower leaves and have slightly smaller inflorescences than plants of ‘Nullabor Spectrum’.
The new Bracteantha can also be compared to the Bracteantha bracteata cultivar ‘Pink Sunrise’, not patented. In side-by-side comparisons conducted by the Inventor in Gapsted, Victoria, Australia, plants of the new Bracteantha are taller, have shorter and narrower leaves, and brighter pink involucral bract coloration than plants of ‘Pink Sunrise’.
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 ‘Florabella Pink’ in a container.

Rooted liners of the new Bracteantha were planted in 15-cm containers and grown for about 8 to 10 weeks. Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
