USPP18353P2 - Euonymus plant named ‘Hooij’ - Google Patents

Abstract

A new and distinct cultivar of Euonymus plant named ‘Hooij’, characterized by its compact outwardly spreading plant habit; yellow and dark green variegated leaves with random speckles; and leaves twisting in aspect.

Description

Botanical designation: Euonymus fortunei.

Cultivar denomination: ‘HOOIJ’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Euonymus, grown as an ornamental shrub, botanically known as Euonymus fortunei and hereinafter referred to by the name ‘Hooij’.

The new Euonymus is a naturally-occurring branch mutation of the Euonymus fortunei cultivar Sunspot, disclosed in U.S. Plant Pat. No. 4,340. The new Euonymus was discovered and selection by the Inventor from within a population of plants of the cultivar Sunspot in a controlled environment in Ederveen, The Netherlands in March, 2001.

Asexual reproduction of the new Euonymus by cuttings in a controlled environment in Ederveen. The Netherlands since June, 2001, has shown that the unique features of this new Euonymus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Hooij has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Hooij’. These characteristics in combination distinguish ‘Hooij’ as a new and distinct cultivar of Euonymus:

• • 1. Compact outwardly spreading plant habit.
  • 2. Yellow and dark green variegated leaves with random speckles.
  • 3. Leaves twisting in aspect.

Plants of the new Euonymus differ from plants of the parent, the cultivar Sunspot, in the following characteristics:

• • 1. Leaves of plants of the new Euonymus are more twisting than leaves of plants of the cultivar Sunspot.
  • 2. Plants of the new Euonymus and the cultivar Sunspot differ in leaf coloration as plants of the cultivar Sunspot are not speckled.

Plants of the new Euonymus can also be compared to plants of the cultivar Harlequin, not patented. Plants of the new Euonymus differ from plants of the cultivar Harlequin in the following characteristics:

• • 1. Plants of the new Euonymus are more tolerant to high light and low temperatures than plants of the cultivar Harlequin.
  • 2. Plants of the new Euonymus and the cultivar Harlequin differ in leaf coloration as plants of the cultivar Harlequin have speckled white and green variegated leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Euonymus, showing 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 Euonymus.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Hooij’ grown in an outdoor nursery.

The photograph at the bottom of the sheet is a close-up view of a typical plant of ‘Hooij’ grown in an outdoor nursery.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Ederveen, The Netherlands, under commercial practice in containers in an outdoor nursery. Plants had been growing for about two years when the photographs and description were taken. 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.
