Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Echinacea purpurea cultivar Jade.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name ‘Jade’.

The new Echinacea was discovered as a chance seedling of two unidentified selections of Echinacea purpurea, not patented. The new Echinacea was discovered and selected by the Inventor in 1995 as a single flowering plant in a controlled environment in Rijpwetering, The Netherlands.

Asexual reproduction of the new Echinacea by divisions was first conducted in Rijpwetering, The Netherlands in 1995. Since then, asexual reproduction by divisions has shown that the unique features of this new Echinacea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Jade 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 ‘Jade’. These characteristics in combination distinguish ‘Jade’ as a new and distinct Echinacea:

1. Upright and somewhat outwardly spreading plant habit.

2. Freely basal branching growth habit.

3. Freely flowering habit.

4. White-colored ray florets and green-colored disc florets.

Plants of the new Echinacea differ primarily from plants of the parent selections in ray and disc floret coloration.

Plants of the new Echinacea can be compared to plants of the Echinacea cultivar White Lustre, not patented. However, plants of the new Echinacea have more inflorescences per lateral stem than plants of the cultivar White Lustre. In addition, plants of the new Echinacea and the cultivar White Lustre differ in ray and disc floret coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Echinacea showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Echinacea. The photograph comprises a side perspective view of several typical flowering plants of ‘Jade’ grown in an outdoor nursery.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in Lisserbroek, The Netherlands, in an outdoor nursery under full sun conditions. In August, when plants were about two years old, the photograph and the observations and measurements were taken. Color references are made to The Royal Horticultural Society Colour Chart, 2001 edition, except where general terms of ordinary dictionary significance are used.
