USPP33567P2 - Ilex tree named ‘IPOC’ - Google Patents

Abstract

A new cultivar of Ilex opaca tree named ‘IPOC’ that is characterized by its upright narrow plant habit when mature; reaching about 17 m in height and 6.7 m in width, its foliage that is slightly large in size, its foliage that is dark green in color, and its heavy berry set.

Description

Botanical classification: Ilex opaca.

Variety denomination: ‘IPOC’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ilex opaca and will be referred to hereafter by its cultivar name, ‘IPOC’. ‘IPOC’ is a new cultivar of American holly grown for use as an ornamental landscape plant.

‘IPOC’ was discovered by the Inventor as a chance seedling that was growing in a boulevard garden in Clinton, S.C. in October 2019. The parentage is unknown, however based on its characteristics it is believed to be derived as a seedling of Ilex opaca.

Asexual propagation of the new cultivar was first accomplished by the Inventor using semi-hardwood stem cuttings in July of 2020 in Rutledge, Ga. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been observed repeatedly and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘IPOC’ as a unique cultivar of Ilex.

• • 1. ‘IPOC’ exhibits an upright narrow plant habit when mature; reaching about 17 m in height and 6.7 m in width.
  • 2. ‘IPOC’ exhibits foliage that is slightly large in size.
  • 3. ‘IPOC’ exhibits foliage that is dark green in color.
  • 4. ‘IPOC’ exhibits a heavy berry set.

‘IPOC’ can be most closely compared to the Ilex opaca cultivars ‘Satyr Hill’ (not patented) and ‘Dan Fenton’ (not patented). ‘Satyr Hill’ is similar to ‘IPOC’ in being a female plant with berry set. ‘Satyr Hill’ differs from ‘IPOC’ in having a less narrow plant habit, foliage that is smaller in size and lighter green in color. ‘Dan Fenton’ is similar to ‘IPOC’ is similar to ‘IPOC’ in in being a female plant with berry set and having foliage that is dark green in color. ‘Dan Fenton’ differs from ‘IPOC’ in having a less narrow plant habit, foliage that is slightly smaller in size, and foliage that is more open (less dense).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of a mature tree of the new cultivar as grown outdoors in Clinton, S.C. The age of the tree is unknown, however it is estimated to be 80 years in age.

The photograph in FIG. 1 provides a side view of the plant habit of ‘IPOC’.

The photograph in FIG. 2 provides a close-up view of foliage and berries of ‘IPOC’.

The 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 Ilex.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of three-year-old plants of the new cultivar grown outdoors in 1-quart containers in Rutledge, Ga. with other data collected from the original discovered plant about 80 years in age. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2001 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
