USPP22187P2 - Gaillardia plant named ‘Georgia Yellow’ - Google Patents

Abstract

The new variety ‘Georgia Yellow’ is provided. The new variety ‘Georgia Yellow’ generally has brighter yellow flowers and a longer blooming period than similar cultivars of Gaillardia plants currently on the market. The new variety ‘Georgia Yellow’ consistently remains in color throughout the growing season (May-October) of North America.

Description

Latin name of the genus and species of the plant claimed: ‘Georgia Yellow’ 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 Yellow’.

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 Yellow’, as herein described and illustrated.

The new Gaillardia plant variety ‘Georgia Yellow’ was selected in Watkinsville, Ga. in 2006. The new variety ‘Georgia Yellow’ generally has brighter yellow flowers and a longer blooming period than similar cultivars of Gaillardia plants currently on the market. The new variety ‘Georgia Yellow’ consistently remains in color throughout the growing season (May-October) of North America.

Pedigree and history: The new Gaillardia plant variety ‘Georgia Yellow’ was one of many seedlings selected in summer 2006 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 ‘Torch Yellow’. Seeds from the open-pollinated Gaillardia plants were collected in fall 2005 and grown out in containers and in the field at Watkinsville, Ga. The resulting seedlings, of which the new variety ‘Georgia Yellow’ was one, were selected in summer 2006. The new Gaillardia plant variety ‘Georgia Yellow’ has been evaluated and tested in Watkinsville, Ga. and Athens, Ga. since 2007.

The new Gaillardia plant variety ‘Georgia Yellow’ 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 Yellow’ 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 Yellow’:

• • 1. Bright yellow flowers that consistently remain in color throughout the growing season (May-October in North America);
  • 2. Long blooming period (at least about 6 months long);
  • 3. Superior landscape performance, illustrating hardiness in U.S. Department of Agriculture (USDA) Zone 7b and possibly perennial in other parts of the U.S.;
  • 4. Compact habit.

The new variety ‘Georgia Yellow’ can be compared to the Gaillardia varieties ‘Mesa Yellow’ and ‘Golden Goblin’.

Comparison to ‘Mesa Yellow’ (not patented). The new variety ‘Georgia Yellow’ is more compact in habit than ‘Mesa Yellow’. For example, the new variety ‘Georgia Yellow’ exhibits smaller dimensions in average plant height, flower diameter, leaf length and leaf width than that of ‘Mesa Yellow’. In addition, the colors of the flowers of ‘Georgia Yellow’ are brighter and more eye-catching than those of ‘Mesa Yellow.’

Comparison to ‘Golden Goblin’ (not patented). The new variety ‘Georgia Yellow’ is more compact in habit than ‘Golden Goblin’. For example, the new variety ‘Georgia Yellow’ exhibits smaller dimensions in average plant height, flower diameter, leaf length and leaf width than that of ‘Golden Goblin’. In addition, the colors of the flowers of ‘Georgia Yellow’ are brighter and more eye-catching than those of ‘Golden Goblin.’
