USPP20239P2 - Euonymus Plant Named ‘Markie’ - Google Patents

Abstract

A new and distinct cultivar of Euonymus plant named ‘Markie’, characterized by its immature leaves of green with yellow green-colored variegation, mature leaves of dark green with yellow green to yellow-colored variegation, large leaves, and moderately vigorous, spreading to broadly upright growth habit.

Description

Latin name of genus and species of plant claimed: Euonymus fortunei.

Variety denomination: ‘Markie’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Euonymus plant botanically known as Euonymus fortunei and hereinafter referred to by the cultivar name ‘Markie’.

The new Euonymus cultivar is a naturally-occurring whole plant mutation. The new cultivar was discovered and selected as a single plant within a population of plants of Euonymus fortunei during August 2005 in a controlled environment at Skerries, County Dublin, Ireland.

Asexual reproduction of the new Euonymus by cuttings in a controlled environment in Lusk, County Dublin, Ireland since August 2005, has shown that the unique features of the Euonymus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Markie’ as a new and distinct cultivar of Euonymus plant:

• • 1. Immature leaves of green with yellow green-colored variegation;
  • 2. Mature leaves of dark green with yellow green to yellow-colored variegation;
  • 3. Large leaves; and
  • 4. Moderately vigorous, spreading to broadly upright growth habit.

Of the many commercially available Euonymus cultivars, the most similar in comparison to the new cultivar is the parent ‘Emerald 'n Gold’, U.S. Plant Pat. No. 2,231. However, in side by side comparisons of plants grown in Lusk, County Dublin, Ireland, plants of the new cultivar differ from plants of ‘Emerald 'n Gold’ in the following characteristics:

• • 1. Plants of the new cultivar have a larger leaf than plants of ‘Emerald 'n Gold’;
  • 2. Plants of the new cultivar have more leaf variegation than plants of ‘Emerald 'n Gold’; and
  • 3. Plants of the new cultivar have a foliage color different from plants of ‘Emerald 'n Gold’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Markie’. The plants were grown for approximately 3 years in a 21 cm container in Lusk, County Dublin, Ireland in a glass-covered greenhouse.

The photograph on the first sheet is a side view of the overall growth and habit of ‘Markie’.

The photograph on the top of the second sheet is a close-up view of the foliage of ‘Markie’.

The photograph on the bottom of the second sheet is a close-up view of a mature leaf of ‘Markie’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined in April, 2008 under natural light conditions.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown at April, 2008 under natural light conditions in Lusk, County Dublin, Ireland in 21 cm containers for approximately 3 years utilizing a soilless growth medium. Measurements and numerical values represent averages of typical plants.
