Dianella plant named ‘Fortunegold’

Abstract

A new and distinct cultivar of Dianella plant named ‘Fortunegold’, characterized by its upright and outwardly arching plant habit; vigorous growth habit; medium plant size; broad and glossy yellow green, grey green and yellow variegated leaves arranged in basal rosettes; violet blue-colored flowers; and good garden performance.

Description

Botanical designation: Dianella hybrid.

Cultivar denomination: ‘FORTUNEGOLD’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dianella plant, botanically known as Dianella hybrid, commonly referred to Blue Flax Lily, typically used as an ornamental landscape plant and hereinafter referred to by the name ‘Fortunegold’.

The new Dianella plant is a naturally-occurring single shoot mutation of an unnamed selection of Dianella hybrid, not patented. The new Dianella plant was discovered and selected by the Inventor on a single plant from within a population of plants of the unnamed selection in a controlled nursery environment in Yandina, Queensland, Australia in 2007.

Asexual reproduction of the new Dianella plant by divisions in Yandina, Queensland, Australia since 2007 has shown that the unique features of this new Dianella plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dianella have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Fortunegold’. These characteristics in combination distinguish ‘Fortunegold’ as a new and distinct Dianella plant:

• • 1. Upright and outwardly arching plant habit.
  • 2. Vigorous growth habit; medium plant size.
  • 3. Broad and glossy yellow green, grey green and yellow variegated leaves arranged in basal rosettes.
  • 4. Violet blue-colored flowers.
  • 5. Good garden performance.

Plants of the new Dianella differ from plants of the mutation parent selection in leaf color as plants of the mutation parent selection have non-variegated green-colored leaves.

Plants of the new Dianella can be compared to plants of Dianella hybrid ‘Variegata’, not patented. In side-by-side comparisons conducted in Yandina, Queensland, Australia, plants of the new Dianella differed primarily from plants of ‘Variegata’ in leaf color as plants of ‘Variegata’ had yellow green and white variegated leaves.

Plants of the new Dianella can also be compared to plants of Dianella hybrid ‘Sougold’, disclosed in U.S. Plant Pat. No. 13,705. In side-by-side comparisons conducted in Yandina, Queensland, Australia, plants of the new Dianella differed primarily from plants of ‘Sougold’ in the following characteristics:

• • 1. Plants of the new Dianella were shorter than plants of ‘Sougold’.
  • 2. Plants of the new Dianella and ‘Sougold’ differed in leaf coloration.
  • 3. Plants of the new Dianella had inflorescences that were taller in relationship to the foliar plane than plants of ‘Sougold’.
  • 4. Plants of the new Dianella and ‘Sougold’ differed in flower coloration.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn and winter in 95-cm (550-ml) containers in a polyethylene-covered shadehouse in Yandina, Queensland, Australia and under cultural practices typical of commercial Dianella plant production. During the production of the plants, day temperatures ranged from 2° C. to 36° C., night temperatures ranged from 2° C. to 27° C. and light levels averaged 33 klux. Vegetative plants were six months old when the photographs and description were taken. Flowering plants were two years old when the photographs and description were taken.
