plant named ‘PIIIC-I’

Abstract

A new cultivar of Ilex crenata plant named, ‘PIIIC-I’, that is characterized by its upright, fastigiate plant habit, its dense, freely branching growth habit, its slightly recurved leaves that are glossy in texture and dark green in color, branches that do not splay or spread apart with age and its lack of fruit production (male flowers).

Description

Botanical classification: Ilex crenata.

Variety denomination: ‘PIIIC-I’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ilex crenata and will be referred to hereafter by its cultivar name, ‘PIIIC-I’. ‘PIIIC-I’ is a new cultivar of holly grown for use as a landscape plant.

The new cultivar of Ilex arose from a breeding program conducted by the Inventors in Watkinsville, Ga. ‘PIIIC-I’ originated as a seedling from seed derived from open pollination of Ilex crenata ‘Sky Pencil’ (not patented). The male parentage is therefore unkown. ‘PIIIC-I’ was selected as a single unique plant in summer of 2009 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by one of the Inventors in Watkinsville, Ga. in 2013. 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 ‘PIIIC-I’ as a unique cultivar of Ilex.

• 1. ‘PIIIC-I’ exhibits an upright, fastigiate plant habit.
• 2. ‘PIIIC-I’ exhbits a dense, freely branching growth habit.
• 3. ‘PIIIC-I’ exhibits slightly recurved leaves that are glossy in texture and dark green in color.
• 4. ‘PIIIC-I’ exhibits branches that do not splay or spread apart with age.
• 5. ‘PIIIC-I’ lacks fruit production as it is a male slection.
  The female parent, ‘Sky Pencil’, differs from ‘PIIIC-I’ in having larger leaves, longer internodes lengths, in producing fruit (female), and in having branches that tend to splay and spread apart. ‘PIIIC-I’ can be most closely compared to Ilex seedlings that also arose from seed planted from open pollination of ‘Sky Pencil’; ‘SS-04-11’ (not patented) and ‘SS-01-11’ (not patented). ‘SS-04-11’ differs from ‘PIIIC-I’ in having larger leaves, longer internodes lengths, a faster growth rate, and branches that tend to flop with age. ‘SS-01-11’ differs from ‘PIIIC-I’ in having an oval shaped plant habit, leaves that are smaller in size, a slower growth rate and in producing fruit (female).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of a seven-year-old plant of the new cultivar as grown in the ground in Watkinsville, Ga.

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

The photograph in FIG. 2 provides a close-up view of the foliage and flowers of ‘PIIIC-I’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Ilex.
