Chrysocephalum plant named ‘Flochrora’

Abstract

A new and distinct cultivar of Chrysocephalum plant named ‘Flochrora’, characterized by its compact and outwardly spreading plant habit; freely flowering habit; inflorescences with yellow to orange-colored disc florets; upright to pendulous flowering stems; and long flowering period.

Description

Botanical designation: Chrysocephalum apiculatum.

Cultivar denomination: ‘Flochrora’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysocephalum plant, botanically known as Chrysocephalum apiculatum, and hereinafter referred to by the name ‘Flochrora’.

The new Chrysocephalum is a product of a planned breeding program conducted by the Inventor in Redland Bay, Queensland, Australia. The objective of the breeding program is to create new compact and long-flowering Chrysocephalum cultivars with numerous and attractive flowers.

The new Chrysocephalum originated from a cross-pollination made by the Inventor in Redland Bay, Queensland, Australia in 2000, of a proprietary selection of Chrysocephalum apiculatum identified as code number 02-036, not patented, as the female, or seed, parent with a proprietary selection of Chrysocephalum apiculatum identified as code number 02-037, not patented, as the male, or pollen, parent. The new Chrysocephalum was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Redland Bay, Queensland, Australia in 2001.

Asexual reproduction of the new Chrysocephalum by vegetative cuttings in a controlled environment in Redland Bay, Queensland, Australia since 2002, has shown that the unique features of this new Chrysocephalum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Flochrora 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 traits have been repeatedly observed and are determined to be the unique characteristics of ‘Flochrora’. These characteristics in combination distinguish ‘Flochrora’ as a new and distinct cultivar of Chrysocephalum:

• • 1. Compact and outwardly spreading plant habit.
  • 2. Freely flowering habit.
  • 3. Inflorescences with yellow to orange-colored disc florets.
  • 4. Upright to pendulous flowering stems.
  • 5. Long flowering period.

Plants of the new Chrysocephalum differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Chrysocephalum and the female parent selection differ in leaf shape.
  • 2. Plants of the new Chrysocephalum are more freely flowering than plants of the female parent selection.
  • 3. Plants of the new Chrysocephalum have longer peduncles than plants of the female parent selection.

Plants of the new Chrysocephalum differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Chrysocephalum have narrower leaves than plants of the male parent selection.
  • 2. Plants of the new Chrysocephalum are more freely flowering than plants of the male parent selection.
  • 3. Plants of the new Chrysocephalum have longer peduncles than plants of the male parent selection.

Plants of the new Chrysocephalum can be compared to plants of the Chrysocephalum cultivar Baby Gold, not patented. In side-by-side comparisons conducted in Redland Bay, Queensland, Australia, plants of the new Chrysocephalum differed from plants of the cultivar Baby Gold in the following characteristics:

• • 1. Plants of the new Chrysocephalum had broader leaves than plants of the cultivar Baby Gold.
  • 2. Plants of the new Chrysocephalum and the cultivar Baby Gold differed in leaf color.
  • 3. Plants of the new Chrysocephalum were more freely flowering than plants of the cultivar Baby Gold.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif. during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Chrysocephalum production. During the production of the plants, day temperatures ranged from about 18° C. to 38° C. and night temperatures ranged from about 16° C. to 24° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about nine weeks old when the photographs and description were taken.
