Description

Botanical designation: Eryngium planum.

Cultivar denomination: ‘Amazing Jackpot’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Eryngium plant, botanically known as Eryngium planum, and hereinafter referred to by the name ‘Amazing Jackpot’.

The new Eryngium originated from a cross-pollination in Rijnsburg, The Netherlands in July, 2000 made by the Inventor of a unnamed seedling selection of Eryngium planum, not patented, as the female, or seed, parent with the Eryngium planum cultivar Blue Candle, not patented, as the male, or pollen, parent. The new Eryngium was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Rijnsburg, The Netherlands in July, 2001.

Asexual reproduction of the new Eryngium by cuttings in a controlled environment in Rijnsburg, The Netherlands since March, 2002, has shown that the unique features of this new Eryngium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Amazing Jackpot 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 ‘Amazing Jackpot’. These characteristics in combination distinguish ‘Amazing Jackpot’ as a new and distinct cultivar of Eryngium:

    • 1. Upright and inverted narrow triangular plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Broadly-branched flower heads with dark blue-colored flowers.

Plants of the new Eryngium differ from plants of the female parent selection primarily in inflorescence form as plants of the parent selection have non-branching inflorescence heads.

Plants of the new Eryngium differ from plants of the male parent, the cultivar Blue Candle, in the following characteristics:

    • 1. Plants of the new Eryngium and the cultivar Blue Candle differ in inflorescence form as plants of the cultivar Blue Candle have non-branching inflorescence heads.
    • 2. Plants of the new Eryngium are not fragrant, whereas plants of the cultivar Blue Candle have an unpleasant fragrance.
    • 3. Flowers of plants of the new Eryngium are sterile whereas flowers of plants of the cultivar Blue Candle are fertile.

Plants of the new Eryngium can also be compared to plants of the Eryngium planum cultivar Blue Ribbon, disclosed in U.S. Plant Pat. No. 7,151. Plants of the new Eryngium differ from plants of the cultivar Blue Ribbon primarily in inflorescence form and flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Eryngium. 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 Eryngium.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘Amazing Jackpot’.

The photograph at the top of the second sheet is a close-up view of typical flowering stems of ‘Amazing Jackpot’.

The photograph at the bottom of the second sheet is a close-up view of a typical inflorescences of ‘Amazing Jackpot’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Rijnsburg, The Netherlands during the late summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Eryngium production. During the production of the plants, day temperatures ranged from 15° C. to 22° C. and night temperatures ranged from 6° C. to 13° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about one year old when the photographs and description were taken.
