Bracteantha plant named ‘Flobramam’

Abstract

A new and distinct cultivar of Bracteantha bracteata plant named ‘Flobramam’, characterized by its vibrant yellow inflorescences, compact plant habit, many inflorescences per plant, narrow leaf width, early flowering, and short peduncles.

Description

The present invention relates to a new and distinct cultivar of Bracteantha plant, botanically known as Bracteantha bracteata, and referred to by the variety denomination ‘Flobramam’. The genus and species were formerly known as Helichrysum bracteatum, and Bracteantha bracteata is synonymous with the more recent botanical designation Xerochrysum bracteatum. The species is also known by the common names strawflower, paper daisy, and everlasting daisy.

The new cultivar is the product of a planned breeding program carried out by the inventor in Redland Bay, Queensland, Australia during November 2001. The objectives of the breeding program were to create new cultivars having a compact bushy habit, narrow leaves, and many inflorescences which have a range of colors and are held above the foliage on short peduncles.

The female or seed parent was unpatented Proprietary Selection 99-268. The characteristics of the female parent are upright plant habit; tall plant size; the leaves are broad in width; late flowering; involucral bracts which are few in number, curve upward giving a cupped shape to the inflorescence head, and are yellow in color; and short peduncles.

The male or pollen parent is unknown since the pollination was performed in isolation using native insects. Possible male parents are unpatented Proprietary Selection 99-420 and unpatented Proprietary Selection 99-579. The characteristics of Proprietary Selection 99-420 are upright plant habit; tall plant size; broad leaf width; large inflorescence size; many involucral bracts which are white in color, and long peduncles. The characteristics of Proprietary Selection 99-579 are upright plant habit; leaf width which is narrower than Selection 99-420 but larger than seed parent 99-268; many involucral bracts which are pale pink in color, and long peduncles.

The new cultivar was selected from the progeny of the described cross by the inventor in October 2002 in Redland Bay, Queensland, Australia. The first act of asexual reproduction of the new cultivar was accomplished when vegetative cuttings were made from the selection in October 2002 and grown in a controlled environment in Redland Bay, Queensland, Australia by or under the supervision of the inventor. Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics of the new cultivar are firmly fixed and are retained through successive generations of asexual reproduction.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, fertilization levels, and day length without, however, any ariance in genotype. The following observations, measurements and comparisons describe plants grown in Redland Bay, Queensland, Australia under normal commercial growing conditions. The age of the plant described is 16 weeks.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and have been determined to be basic characteristics of the new cultivar, which in combination distinguish the new cultivar as being new and distinct:

• • 1. Vibrant yellow inflorescences.
  • 2. Compact plant habit.
  • 3. Many inflorescences per plant.
  • 4. Narrow leaf width.
  • 5. Early flowering.
  • 6. Short peduncles.

The new cultivar differs from Proprietary Selections 99-420 and 99-579 by its vibrant yellow flowers, compact plant habit, narrow leaf width, earlier flowering, more flowers per plant, and short peduncle length. The new cultivar differs from its female parent by its compact plant habit, narrow leaf width, earlier flowering, and more flowers per bush.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new cultivar is the cultivar ‘Redbragol’, disclosed in U.S. Plant Pat. No. 12,988. Based on comparative testing conducted in Redland Bay, Queensland, Australia, plants of the new cultivar differ from plants of the comparison cultivar in the characteristics as described in Table 1:

	Trait	‘FLOBRAMAM’	‘REDBRAGOL’
	Internode length	short	long
	Leaf width	narrow	broad
	Inflorescence number	many	few
	Inflorescence size	medium	large
	Plant height	medium	tall
	Flowering time	early	late

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The top photograph shows an overall view of a typical flowering plant of the new cultivar grown in a 14 cm container for about 10 weeks.

The bottom photograph shows a close up view of a typical inflorescence of the new cultivar.

The colors in the photographs show the colors as true as is reasonably possible with colored reproductions of this type. If any differences exist between the photographic color and the color values described below, the values in the detailed description are accurate.
