Abstract

A new cultivar of Gaillardia named ‘ORANGES AND LEMONS’, an herbaceous perennial, that is distinguishable by an erect, compact habit, large composite planar sterile inflorescences which are composed of ray florets which are orange and yellow in color and disc florets which are orange in color. In combination these traits set ‘ORANGES AND LEMONS’ apart from all other existing varieties of Gaillardia known to the inventor.

Description

Botanical designation: Genus: Gaillardia. Species: ×grandiflora.

Denomination: ‘ORANGES AND LEMONS’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of blanket flower, an herbaceous perennial that is grown for use as an ornamental landscape and container plant. The new invention is known botanically as Gaillardia×grandiflora and will be referred to hereinafter by the cultivar name ‘ORANGES AND LEMONS’. Gaillardia is in the family Compositae, under which the commonly referred to “flower” is actually the inflorescence, and is made up of smaller ray florets and disc florets. The ray florets themselves have the appearance of “petals”.

‘ORANGES AND LEMONS’ arose in the summer of 2002 at the inventor's nursery in Hampshire, England as a single chance seedling which was discovered, isolated and then asexually propagated by the inventor as described herein.

The inventor had grown a crop of plants of the variety Gaillardia ‘Dazzler’ (unpatented), hereinafter referred to as ‘Dazzler’, from commercially available seed of ‘Dazzler’ which the inventor had sown in February 2002. In June or July 2002, by which time the seedlings of ‘Dazzler’ had been transplanted into 9 cm diameter containers and were in flower, the inventor observed a single plant which displayed larger inflorescences with an uncharacteristic orange coloration of the ray florets. Each ray floret was observed to be approximately twenty-five percent longer and broader than the typical ray floret of ‘Dazzler’. The inflorescences themselves were observed to be flat or planar rather than concave as is typical of ‘Dazzler’.

The female parent of ‘ORANGES AND LEMONS’ is Gaillardia ‘Dazzler’ (unpatented). The male parent plant is unknown. ‘ORANGES AND LEMONS’ differs from the parent plant, Gaillardia ‘Dazzler’ in respect of the coloration of its ray florets, the size and form of each inflorescence, the overall height and habit of a mature plant, and fertility or sterility. Specifically, the ray florets of ‘ORANGES AND LEMONS’ are colored orange and yellow, whereas the ray florets of ‘Dazzler’ are colored predominantly red; an individual inflorescence of ‘ORANGES AND LEMONS’ is approximately twenty-five percent larger than an individual inflorescence of ‘Dazzler’ and is also flat rather than concave in form; a mature plant of ‘ORANGES AND LEMONS’ is 10 cm to 20 cm taller than ‘Dazzler’ and is also more stiffly erect; and ‘ORANGES AND LEMONS’ is sterile whereas ‘Dazzler’ is fertile and sets viable seed.

The first asexual reproduction of ‘ORANGES AND LEMONS’ was accomplished in September 2002 when the inventor removed and rooted approximately ten nodal cuttings from the originally discovered and isolated plant. The cuttings rooted successfully and since that time subsequent generations have been determined stable and true to type when compared with the original selection which the inventor has retained.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘ORANGES AND LEMONS’. These traits in combination distinguish ‘ORANGES AND LEMONS’ from all other existing varieties of Gaillardia×grandiflora known to the inventor. ‘ORANGES AND LEMONS’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

- 1. ‘ORANGES AND LEMONS’ has an erect, compact habit.
- 2. ‘ORANGES AND LEMONS’ is an herbaceous perennial.
- 3. ‘ORANGES AND LEMONS’ exhibits large composite planar inflorescences composed of ray florets which are orange and yellow in color and disc florets which are orange in color.
- 4. A mature one-year old plant of ‘ORANGES AND LEMONS’ is approximately 700 mm to 800 mm in height and 600 mm. in width at maturity.
- 5. ‘ORANGES AND LEMONS’ is hardy to USDA Zone 5.
- 6. ‘ORANGES AND LEMONS’ is sterile.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Gaillardia cultivar ‘ORANGES AND LEMONS’ showing the colors as true as is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describes the actual colors of the new variety ‘ORANGES AND LEMONS’.

The Drawing labeled as FIG. 1 depicts a one-season old whole plant of ‘ORANGES AND LEMONS’ grown out of doors in a 2-liter container in Hampshire, England. This Drawing depicts the erect and dense habit of ‘ORANGES AND LEMONS’.

The Drawing labeled as FIG. 2 depicts a close-up view of a single inflorescence of ‘ORANGES AND LEMONS’. This Drawing depicts the orange and yellow coloration of the ray florets.

The Drawing labeled as FIG. 3 depicts close-up views of one inflorescence of ‘ORANGES AND LEMONS’ together with two inflorescences taken from the parent variety, Gaillardia ‘Dazzler’. This Drawing depicts the contrasting coloration of the ray florets: orange and yellow in ‘ORANGES AND LEMONS’ and predominantly red in Gaillardia ‘Dazzler’.

The Drawings were made by printing onto semi-gloss proprietary ink-jet photographic paper images taken with a digital camera and although inflorescence and foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by such means.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Gaillardia×grandiflora cultivar ‘ORANGES AND LEMONS’. Observations, measurements, values and comparisons were compiled in Cambridge, England and cross-checked with the inventor's original selection in Hampshire, England. The observations were made during the summer of 2004 utilizing one year old plants grown out-of-doors in a 2 liter container. Color determinations are made in accordance with the 2001 edition of The Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.
