Description

Botanical designation: Gaillardia sp. X Gaillardia x grandiflora.
Cultivar denomination: ‘G15272’.
CROSS-REFERENCE TO A RELATED APPLICATION AND STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT
This application claims priority to a Canadian Plant Breeders' Rights application filed on May 17, 2019, application number 19-9869. There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed Plant Breeder's Rights documents.
The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Gaillardia plant, botanically known as the interspecific hybrid, Gaillardia sp. X Gaillardia x grandiflora, and hereinafter referred to by the name ‘G15272’.
The new Gaillardia plant is a product of a planned breeding program conducted by the Inventor in Bellefonte, Pa. The objective of the breeding program is to create new sterile Gaillardia plants with numerous attractive inflorescences and resistant to pathogens common to Gaillardia plants.
The new Gaillardia plant originated from a cross-pollination in October, 2014 of a proprietary selection of Gaillardia sp. identified as code number G2X-32015-2, not patented, as the female, or seed, parent with a proprietary selection of Gaillardia x grandiflora identified as code number G2X-32014-1, not patented, as the male, or pollen, parent. The new Gaillardia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Bellefonte, Pa. on Sep. 15, 2015.
Asexual reproduction of the new Gaillardia plant by vegetative terminal cuttings in Bellefonte, Pa., since October, 2015 has shown that the unique features of this new Gaillardia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Gaillardia have not been observed under all possible combinations of 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 ‘G15272’. These characteristics in combination distinguish ‘G15272’ as a new and distinct Gaillardia plant:
    • 1. Upright to outwardly spreading plant habit.
    • 2. Vigorous growth habit and moderate growth rate.
    • 3. Freely branching habit; dense and bushy habit.
    • 4. Strong leaves that resist leaf pathogens.
    • 5. Early and freely flowering habit.
    • 6. Single sterile inflorescences with bright red-colored ray florets with bright yellow-colored apices.
    • 7. Good garden performance.
Plants of the new Gaillardia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Gaillardia are more vigorous and more outwardly spreading than plants of the female parent selection.
    • 2. Margins of leaves of plants of the new Gaillardia are not as deeply dentate as margins of leaves of plants of the female parent selection.
    • 3. Plants of the new Gaillardia have single-type inflorescences whereas plants of the female parent selection have double-type inflorescences.
    • 4. Disc florets of plants of the new Gaillardia are sterile whereas disc florets of plants of the female parent selection are fertile.
Plants of the new Gaillardia differ primarily from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Gaillardia are more vigorous and more outwardly spreading than plants of the male parent selection.
    • 2. Margins of leaves of plants of the new Gaillardia are irregularly and shallowly dentate whereas margins of leaves of plants of the male parent selection are entire.
    • 3. Disc florets of plants of the new Gaillardia are sterile whereas disc florets of plants of the male parent selection are fertile.
Plants of the new Gaillardia can be compared to plants of Gaillardia x grandiflora ‘Celebration’, disclosed in U.S. Plant Pat. No. 26,969. In side-by-side comparisons, plants of the new Gaillardia differ from plants of ‘Celebration’ in the following characteristics:
    • 1. Plants of the new Gaillardia are more vigorous than and not as compact as plants of ‘Celebration’.
    • 2. Margins of leaves of plants of the new Gaillardia are irregularly and shallowly dentate whereas margins of leaves of plants of ‘Celebration’ are mostly entire.
    • 3. Leaves of plants of the new Gaillardia are more resistant to leaf pathogens than leaves of plants of ‘Celebration’.
    • 4. Plants of the new Gaillardia flower throughout the summer whereas plants of ‘Celebration’ typically only flower until mid to late summer in Central Pennsylvania.
    • 5. Disc florets of plants of the new Gaillardia are sterile whereas disc florets of plants of ‘Celebration’ are fertile.
Plants of the new Gaillardia can also be compared to plants of Gaillardia x grandiflora ‘Fanfare’, disclosed in U.S. Plant Pat. No. 15,892. In side-by-side comparisons, plants of the new Gaillardia differ from plants of ‘Fanfare’ in the following characteristics:
    • 1. Plants of the new Gaillardia are more vigorous than and not as compact as plants of ‘Fanfare’.
    • 2. Margins of leaves of plants of the new Gaillardia are irregularly and shallowly dentate whereas margins of leaves of plants of ‘Fanfare’ are mostly entire.
    • 3. Leaves of plants of the new Gaillardia are more resistant to leaf pathogens than leaves of plants of ‘Fanfare’.
    • 4. Plants of the new Gaillardia flower throughout the summer whereas plants of ‘Fanfare’ typically only flower until mid to late summer in Central Pennsylvania.
    • 5. Ray florets of plants of the new Gaillardia are obovate in shape whereas ray florets of plants of ‘Fanfare’ are quilled.
    • 6. Disc florets of plants of the new Gaillardia are sterile whereas disc florets of plants of ‘Fanfare’ are fertile.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Gaillardia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gaillardia plant.
At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘G15272’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘G15272’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the spring and summer in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Gaillardia production.
