Abstract

A new and distinct cultivar of Coreopsis plant named ‘Jethro Tull’, characterized by its compact, upright, outwardly spreading and mounded plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; rotate inflorescences with tubular golden yellow-colored ray florets; and strong peduncles that hold the inflorescences above the foliar plane.

Description

Botanical designation: Coreopsis auriculata×Coreopsis lanceolata.
Cultivar denomination: ‘Jethro Tull’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Coreopsis plant, botanically known as Coreopsis auriculata×Coreopsis lanceolata, and hereinafter referred to by the name ‘Jethro Tull’.
The new Coreopsis originated from a cross-pollination made by the Inventor in Atlanta, Ga. in May, 2002, of the Coreopsis auriculata cultivar Zamfir, not patented, as the female, or seed, parent with the Coreopsis lanceolata cultivar Early Sunrise, not patented, as the male, or pollen, parent. The new Coreopsis was discovered and selected by the Inventor as a single flowering plant from the within the progeny of the stated cross-pollination grown in a controlled environment in Atlanta, Ga. in May, 2003.
Asexual reproduction of the new Coreopsis by vegetative cuttings in a controlled environment in Alpharetta, Ga. since July, 2003, has shown that the unique features of this new Coreopsis are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Jethro Tull has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Jethro Tull’. These characteristics in combination distinguish ‘Jethro Tull’ as a new and distinct cultivar of Coreopsis:
    • 1. Compact, upright, outwardly spreading and mounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely basal branching habit.
    • 4. Freely flowering habit.
    • 5. Rotate inflorescences with tubular golden yellow-colored ray florets.
    • 6. Strong peduncles that hold the inflorescences above the foliar plane.
Plants of the new Coreopsis differ from plants of the female parent, the cultivar Zamfir, in the following characteristics:
    • 1. Plants of the new Coreopsis are taller than plants of the cultivar Zamfir.
    • 2. Plants of the new Coreopsis and the cultivar Zamfir differ in leaf shape.
    • 3. Plants of the new Coreopsis have smaller inflorescences than plants of the cultivar Zamfir.
    • 4. Inflorescences of plants of the new Coreopsis have more ray florets than inflorescences of plants of the cultivar Zamfir.
    • 5. Plants of the new Coreopsis have longer ray florets than plants of the cultivar Zamfir.
Plants of the new Coreopsis differ from plants of the male parent, the cultivar Early Sunrise, in the following characteristics:
    • 1. Plants of the new Coreopsis are more compact than plants of the cultivar Early Sunrise.
    • 2. Inflorescences of plants of the new Coreopsis have fewer ray florets than inflorescences of plants of the cultivar Early Sunrise.
    • 3. Ray florets of plants of the new Coreopsis are tubular in shape whereas ray florets of plants of the cultivar Early Sunrise are flat and not tubular in shape.
Plants of the new Coreopsis can be compared to plants of the Coreopsis cultivar Creme Brulee, disclosed in U.S. Plant Pat. No. 16,096. In side-by-side comparisons conducted in Tolar, Tex. plants of the new Coreopsis differed from plants of the cultivar Creme Brulee in the following characteristics:
    • 1. Inflorescences of plants of the new Coreopsis had fewer ray florets than inflorescences of plants of the cultivar Creme Brulee.
    • 2. Ray florets of plants of the new Coreopsis were tubular in shape whereas ray florets of plants of the cultivar Creme Brulee were flat and not tubular in shape.
    • 3. Ray florets of plants of the new Coreopsis were darker yellow in color than ray florets of plants of the cultivar Creme Brulee.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Coreopsis. The photographs show 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 Coreopsis.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Jethro Tull’ grown in an outdoor nursery.
The photograph on second sheet is a close-up view of typical inflorescences and leaves of ‘Jethro Tull’.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Atlanta, Ga. during the spring and summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Coreopsis production. During the production of the plants, day temperatures ranged from about 24° C. to 27° C. and night temperatures ranged from about 16° C. to 21° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about eight months old when the photographs and description were taken.
