Description

Latin name of the genus and species of the plant claimed: ‘Georgia Sunset’ is a Gaillardia plant that is a hybrid of the genus and species Gaillardia×grandiflora.

Variety denomination: The new Gaillardia plant claimed is of the variety denominated ‘Georgia Sunset’.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of Gaillardia plant botanically known as a Gaillardia×grandiflora and herein referred to as ‘Georgia Sunset’, as herein described and illustrated.

The new Gaillardia plant variety ‘Georgia Sunset’ was selected in Watkinsville, Ga. in 2007. The new variety ‘Georgia Sunset’ generally has bright two-tone flowers, a large flower size, and persistent flowering throughout the growing season.

Pedigree and history: The new Gaillardia plant variety ‘Georgia Sunset’ was one of many seedlings selected in summer 2007 in Watkinsville, Ga. and originated from open pollination of Gaillardia plants in the University of Georgia Trial Gardens in Athens, Ga. The maternal plant is likely the Gaillardia plant ‘Arizona Sun’ (unpatented). Seeds from the open-pollinated Gaillardia plants were collected in fall 2006 and grown out in containers and in the field at Watkinsville, Ga. The resulting seedlings, of which the new variety ‘Georgia Sunset’ was one, were selected in summer 2007. The new Gaillardia plant variety ‘Georgia Sunset’ has been evaluated and tested in Watkinsville, Ga. and Athens, Ga. since 2007.

The new Gaillardia plant variety ‘Georgia Sunset’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, rooted stem cuttings. Plants from stem cuttings have been directly planted in the ground.

SUMMARY OF THE INVENTION

The new Gaillardia plant variety ‘Georgia Sunset’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed in Watkinsville and Athens, Ga., and are determined to be the unique characteristics of the new Gaillardia plant variety ‘Georgia Sunset’:

    • 1. Bright two-tone (orange and yellow) flowers;
    • 2. Large flower size;
    • 3. Persistent flowering for at least four months during the growing season;
    • 4. Excellent landscape performance, illustrating hardiness in U.S. Department of Agriculture (USDA) Zone 7b and possibly perennial in other parts of the U.S.;
    • 5. Vigorous habit

The new variety ‘Georgia Sunset’ can be compared to the Gaillardia varieties ‘Sunburst Burgundy’ (unpatented) and ‘Sunburst Scarlet Halo’ (unpatented).

Comparison to ‘Sunburst Burgundy’. The new variety ‘Georgia Sunset’ is in flower longer than ‘Sunburst Scarlet Halo.’

Comparison to ‘Sunburst Scarlet Halo’. The new variety ‘Georgia Sunset’ is more vigorous than ‘Sunburst Scarlet Halo’. In addition, the new variety ‘Georgia Sunset’ is in flower longer than ‘Sunburst Scarlet Halo.’
