USPP21634P2 - Euonymus plant named ‘Hayman’ - Google Patents

Abstract

A new and distinct cultivar of Euonymus plant named ‘Hayman’, characterized by its compact, upright and mounding plant habit; relatively rapid growth rate; freely branching habit; relatively small and fine leaves; and attractive autumn leaf color.

Description

Botanical designation: Euonymus alata.

Cultivar denomination: ‘HAYMAN’.

BACKGROUND OF THE INVENTION

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

The new Euonymus plant originated from an open-pollination during the autumn of 2000 of Euonymus alata ‘Rudy Haag’, not patented, as the female, or seed, parent with an unknown selection of Euonymus alata as the male, or pollen, parent. The new Euonymus plant was discovered and selected by the Inventor during the autumn of 2002 as a single plant within the progeny of the stated open-pollination in a controlled environment in Louisville, Ky.

Asexual reproduction of the new Euonymus plant by softwood cuttings in a controlled environment in Louisville, Ky. since the spring of 2003, has shown that the unique features of this new Euonymus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Euonymus have 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 ‘Hayman’. These characteristics in combination distinguish ‘Hayman’ as a new and distinct cultivar of Euonymus:

• • 1. Compact, upright and mounding plant habit.
  • 2. Relatively rapid growth rate.
  • 3. Freely branching habit.
  • 4. Relatively small and fine leaves.
  • 5. Attractive autumn leaf color.

Plants of the new Euonymus differ primarily from plants of the female parent, ‘Rudy Haag’, in the following characteristics:

• • 1. Plants of the new Euonymus are larger than plants of ‘Rudy Haag’.
  • 2. Plants of the new Euonymus grow faster than plants of ‘Rudy Haag’.
  • 3. Plants of the new Euonymus are more freely branching than plants of ‘Rudy Haag’.
  • 4. Leaves of plants of the new Euonymus are smaller and finer than leaves of plants of ‘Rudy Haag’.
  • 5. Plants of the new Euonymus and ‘Rudy Haag’ differ in autumn leaf color.

Plants of the new Euonymus can be compared to plants of Euonymus alata ‘Compacta’, not patented. Plants of the new Euonymus differ from plants of ‘Compacta’ in the following characteristics:

• • 1. Plants of the new Euonymus are much smaller than plants of ‘Compacta’.
  • 2. Plants of the new Euonymus are more freely branching than plants of ‘Compacta’.
  • 3. Leaves of plants of the new Euonymus are smaller and finer than leaves of plants of ‘Compacta’.
  • 4. Plants of the new Euonymus and ‘Compacta’ differ in autumn leaf color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Hayman’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical plant of ‘Hayman’ grown in an outdoor nursery during the autumn.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Grand Haven, Mich., under commercial practice in containers in an outdoor nursery. Plants were 3.5 years old when the photographs and description were taken. 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.
