plant named ‘Jazzy Wheeler’

Abstract

A new cultivar of Gaillardia, ‘Jazzy Wheeler’, characterized by its large inflorescences with ray florets that exhibit yellow-orange centers and yellow tips, its numerous blooms produced throughout the growing season, and its dwarf, spreading habit and reliably perennial plant habit with hardiness in U.S.D.A. Zones 3 to 9.

Description

Botanical classification: Gaillardia aristata.

Variety denomination: ‘Jazzy Wheeler’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived the Inventor's breeding program that is entitled Gaillardia Plant Named ‘Fancy Wheeler’ (U.S. Plant Pat. No. 22,016).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gaillardia plant, botanically known as Gaillardia aristata ‘Jazzy Wheeler’ and will be referred to hereinafter by its cultivar name, ‘Jazzy Wheeler’.

‘Jazzy Wheeler’ was derived from a controlled breeding program conducted by the Inventor at a nursery in Schwamstedt, Germany. The breeding program focuses on obtaining new cultivars of Gaillardia with compact and floriferous plant habit in a range of flower colors. ‘Jazzy Wheeler’ was selected in 2006 by the Inventor as a single unique plant derived from a cross made in 2005 between unnamed plants from his breeding program with the female parent identified with accession No. G04051 and the male parent identified with accession No. G04045.

Asexual reproduction of the new cultivar was first accomplished via stem cuttings in Lisse, The Netherlands in 2006. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar of Gaillardia. These attributes in combination distinguish ‘Jazzy Wheeler’ as unique from all other varieties of Gaillardia known to the inventor.

• • 1. ‘Jazzy Wheeler’ exhibits large inflorescences with ray florets that exhibit yellow-orange centers and yellow tips.
  • 2. ‘Jazzy Wheeler’ is hardy in U.S.D.A. Zones 3 to 9.
  • 3. ‘Jazzy Wheeler’ is reliably perennial with a dwarf, spreading habit.
  • 4. ‘Jazzy Wheeler’ produces numerous blooms throughout the growing season.

‘Jazzy Wheeler’ can be compared to its parents. The female parent differs from ‘Fancy Wheeler’ in having red coloration on the ray florets and being less vigorous. The male parent differs from ‘Fancy Wheeler’ in having red coloration on the ray florets. ‘Fancy Wheeler’ can also be compared to Gaillardia cultivars ‘Arizona Sun’, ‘Primavera’ (both unpatented) and ‘Oranges and Lemons’ (U.S. Plant Pat. No. 17,092). ‘Arizona Sun’ and ‘Primavera’ differ in having taller habits, smaller blooms and shorter blooming periods, and inflorescences that are less uniformly bi-colored. ‘Arizona Sun’ and ‘Primavera’ also differ in being less reliably perennial. ‘Oranges and Lemons’ differs in having a taller habit, smaller inflorescences, and in being less reliably perennial. ‘Jazzy Wheeler’ can also be compared to ‘Fancy Wheeler’ that differs from ‘Jazzy Wheeler’ in having inflorescences with ray florets that exhibit red centers with yellow tips.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Gaillardia. The photographs were taken of a plant two years in age as grown outdoors in a 1-gallon container in Lisse, the Netherlands.

The photograph in FIG. 1 is a side view of ‘Jazzy Wheeler’ in bloom.

The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Jazzy Wheeler’. The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description more accurately describe the colors of the new Gaillardia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar as grown outdoors under natural lighting in a trial bed in Waseca, Minn. and observed over a period of two years. The detailed botanical data was collected from three year-old plants grown in 4-liter containers in a cold-storey greenhouse in Lisse, The Netherlands under average day temperatures ranging from 12° to 22° C. and night temperatures ranging from 3° and 14° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
