Eryngium plant named ‘Sunny Jackpot’

Abstract

A new and distinct cultivar of Eryngium plant named ‘Sunny Jackpot’, characterized by its upright and inverted triangular plant habit; moderately vigorous growth habit; green and yellow green variegated foliage; and flower heads with green and blue-colored flowers.

Description

Botanical designation: Eryngium planum.

Cultivar denomination: ‘Sunny 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 ‘Sunny Jackpot’.

The new Eryngium was discovered by the Inventors in a controlled environment in Rijnsburg, The Netherlands, in July, 2005, as a naturally-occurring whole plant mutation of the Eryngium planum cultivar Blue Dream, not patented. The new Eryngium was observed as a single plant from within a population of plants of the cultivar Blue Dream. The selection of this plant was based on its unique variegated foliage.

Asexual reproduction of the new Eryngium by cuttings in a controlled environment in Rijnsburg, The Netherlands since July, 2005, 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 Sunny 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 ‘Sunny Jackpot’. These characteristics in combination distinguish ‘Sunny Jackpot’ as a new and distinct cultivar of Eryngium:

• • 1. Upright and inverted triangular plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Green and yellow green variegated foliage.
  • 4. Flower heads with green and blue-colored flowers.

Plants of the new Eryngium differ from plants of the parent, the cultivar Blue Dream, primarily in foliage color as plants of the cultivar Blue Dream have solid green-colored leaves.

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 foliage color as plants of the cultivar Blue Dwarf have solid green-colored leaves.

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.
