Abstract

A new cultivar of Gaillardia named ‘Celebration’ that is distinguishable by a long blooming period, compact habit and large single inflorescences composed of one row of deep red ray florets surrounding a disc whose disc and disc florets are entirely red when the inflorescence is fully developed, is disclosed.

Description

Genus and species: Gaillardia×grandiflora.

Variety denomination: ‘Celebration’.

BACKGROUND

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

‘Celebration’ originated and was selected from a large population of hybrid seedlings from a Gaillardia breeding program which was started by the inventors in 2006. The breeding program was conducted in a greenhouse nursery in West Sussex, United Kingdom. The aims of the breeding program were to produce novel combinations of flower colors and flower forms which are borne on well-branched plants with sturdy growth habits. The controlled hybridization was carried out using combinations of selected named varieties and selected unnamed and unreleased seedlings retained from previous breeding cycles. The hybridization which led to the selection of ‘Celebration’ was carried out during 2007 using Gaillardia ‘Burgunder’ (unpatented) as the male parent and a proprietary unreleased Gaillardia seedling known as ‘G5’ (unpatented) as the female parent. ‘Celebration’ was selected in 2009 for its bright red ray flowers, which are produced continually from May through November in the United Kingdom. ‘Celebration’ was also selected for its compact mounding habit and clean dark green foliage.

Asexual reproduction of the new cultivar ‘Celebration’ was first accomplished in October 2009. The method of asexual propagation used was shoot cuttings taken from the lateral branches of plants which were growing in an unheated greenhouse in West Sussex, United Kingdom. Subsequent asexual propagations have been carried out in the same greenhouse using both vegetative cuttings and root cuttings. ‘Celebration’ has been determined to be stable and reproduces true to type in successive generations of asexual reproduction by both vegetative cuttings and root cuttings.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Celebration’. ‘Celebration’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

• • 1. ‘Celebration’ exhibits a compact and naturally branching plant habit.
  • 2. ‘Celebration’ exhibits large single inflorescences composed of one row of deep red ray florets.
  • 3. The disc of a fully expanded inflorescence of ‘Celebration’ is comprised entirely of red disc florets.
  • 4. ‘Celebration’ blooms continually from early spring until late fall.
  • 5. After one year's growth in a 3 liter container, ‘Celebration’ is 35 cm to 40 cm in height and 40 cm to 45 cm in width.
  • 6. ‘Celebration’ is hardy in USDA zone 5.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Gaillardia cultivar ‘Celebration’ showing the colors as true as it 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 more accurately describes the actual colors of the new variety ‘Celebration’.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Celebration’. Observations, measurements, values, and comparisons were collected in August, 2014 in Santa Barbara, Calif. from a fifteen month old plant grown outdoors in full sun in a 3 gallon container. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘Celebration’ is distinguishable from the female parent, ‘G5’ as follows. Whereas the female parent exhibits red-bronze colored flowers, the flowers of ‘Celebration’ are bright red in color. ‘Celebration’ is more floriferous and exhibits a more compact plant habit than the female parent.

‘Celebration’ is distinguishable from the male parent, ‘Burgunder’ as follows. Whereas the male parent exhibits wine-red almost purple colored flowers, the flowers of ‘Celebration’ are bright red in color. Additionally, the male parent exhibits a double row of petals while ‘Celebration’ exhibits a single row of petals.

The variety of Gaillardia which most closely resembles ‘Celebration’ is the variety, ‘Burgunder’ (unpatented). ‘Celebration’ exhibits bright red colored flowers, while ‘Burgunder’ exhibits wine red and almost purple colored flowers. Additionally, ‘Celebration’ bears many more flowers than “Burgunder’ and exhibits a more compact plant habit.
