Eryngium plant named ‘Paradise Jackpot’

Abstract

A new and distinct cultivar of Eryngium plant named ‘Paradise Jackpot’, characterized by its upright and inverted narrow triangular plant habit; moderately vigorous growth habit; freely branching habit; and compound flower heads with blue-colored flowers.

Description

Botanical designation: Eryngium planum.

Cultivar denomination: ‘Paradise 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 ‘Paradise Jackpot’.

The new Eryngium was discovered by the Inventor in a controlled environment in Rijnsburg, The Netherlands, in July, 2001, as a naturally-occurring whole plant mutation of an unnamed seedling selection of Eryngium planum, not patented. The new Eryngium was observed as a single plant from within a population of plants of the parent selection. The selection of this plant was based on its unique inflorescence form.

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 Paradise 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 ‘Paradise Jackpot’. These characteristics in combination distinguish ‘Paradise 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. Compound flower heads with blue-colored flowers.

Plants of the new Eryngium differ from plants of the parent selection primarily in inflorescence form as plants of the parent selection have simple (not compound) inflorescence heads.

Plants of the new Eryngium can also be compared to plants of the Eryngium planum cultivar Blue Dwarf, not patented. Plants of the new Eryngium differ from plants of the cultivar Blue Dwarf primarily in inflorescence form as plants of the cultivar Blue Dwarf have simple (not compound) inflorescence heads.

The photograph at the bottom of the second sheet is a close-up view of a typical compound inflorescence of ‘Paradise 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.
