USPP36895P2 - Ilex plant named ‘Golden Hoogendoorn’ - Google Patents

Abstract

A new and distinct Ilex plant named ‘Golden Hoogendoorn’, characterized by its relatively compact, upright to outwardly spreading and mounding plant habit; freely branching habit; dense and bushy growth habit; semi-glossy leaves that are initially yellowish green in color becoming darker green with development; and relative tolerance to high temperature and high humidity conditions.

Description

Botanical designation: Ilex crenata.

Cultivar denomination: ‘GOLDEN HOOGENDOORN’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct Ilex plant, botanically known as Ilex crenata and hereinafter referred to by the name ‘Golden Hoogendoorn’.

The new Ilex plant is a naturally-occurring branch mutation of Ilex crenata ‘Hoogendoorn’, not patented. The new Ilex plant was discovered and selected by the Inventor on a single plant of ‘Hoogendoorn’ within a population of plants of ‘Hoogendoorn’ in a controlled environment in Lucedale, Mississippi on Oct. 11, 2016.

Asexual reproduction of the new Ilex plant by vegetative cuttings in a controlled environment in Lucedale, Mississippi since Feb. 8, 2017 has shown that the unique features of this new Ilex plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Ilex have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Golden Hoogendoorn’. These characteristics in combination distinguish ‘Golden Hoogendoorn’ as a new and distinct Ilex plant:

• • 1. Relatively compact, upright to outwardly spreading and mounding plant habit.
  • 2. Freely branching habit; dense and bushy growth habit.
  • 3. Semi-glossy leaves that are initially yellowish green in color becoming darker green with development.
  • 4. Relatively tolerant to high temperature and high humidity conditions.

Plants of the new Ilex differ from plants of the mutation parent, ‘Hoogendoorn’, primarily in developing leaf color as leaves of plants of the new Ilex are initially yellowish green in color whereas leaves of ‘Hoogendoorn’ are initially medium green in color. In addition, plants of the new Ilex are more tolerant to high temperature and high humidity conditions than plants of ‘Hoogendoorn’.

Plants of the new Ilex can be compared to plants of Ilex crenata ‘Adorned’, not patented. Plants of the new Ilex differ from plants of ‘Adorned’, primarily in landscape performance as plants of the new Ilex are more tolerant to high temperature and high humidity conditions than plants of ‘Adorned’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Ilex plant. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Ilex plant.

The photograph is a side perspective view of a typical plant of ‘Golden Hoogendoorn’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring and summer in three-gallon containers in an outdoor nursery in Park Hill, Oklahoma and under cultural practices typical of commercial Ilex production. During the production of the plants, day temperatures averaged 33° C. and night temperatures averaged 21° C. Plants were 30 months old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
