Abstract

A new and distinct cultivar of Ilex plant named ‘NCIC1’ is disclosed, characterized by its compact, upright, rounded growth habit, and persistent, vivid yellow foliage. The new variety is an Ilex, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Ilex crenata.
Variety denomination: ‘NCIC1’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct Ilex crenata cultivar hereinafter referred to by the cultivar name ‘NCIC1’. This new Ilex crenata was developed through a breeding program at a research nursery, located in Mills River, North Carolina. The intent of the breeding program was to develop Ilex varieties with persistent, vivid yellow foliage and a compact plant habit. ‘NCIC1’ was selected from an F2 population resulting from the parentage Ilex crenata ‘Drops of Gold’, U.S. Plant Pat. No. 14,420, and Ilex crenata ‘Sky Pencil’, unpatented, and Ilex crenata ‘Golden Gem’, unpatented. The direct parents (F1 generation of the breeding program) are unnamed and unpatented. The crossing resulting in the new variety was made in 2013. Ilex crenata ‘NCIC1’ was found and selected as an interesting new cultivar in 2014 at the same nursery in Mills River, North Carolina.
The first asexual propagation of ‘NCIC1’ occurred in July 2016 by rooting stem cuttings at the same research nursery in Mills River, North Carolina. ‘NCIC1’ roots readily from softwood cuttings treated with a basal dip of 3,000-5,000 ppm indole butyric acid (potassium salt) in water. ‘NCIC1’ was repeatedly reproduced by vegetative cuttings over a seven-year period and has been found to retain its distinctive characteristics through successive asexual propagations.
Date of first public exposure was Jun. 27, 2023, in the United States. This was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Jun. 27, 2023, and the filing of this application fall within the exception allowed under 102(b)(1).
SUMMARY OF THE INVENTION
‘NCIC1’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.
The following traits have been observed and represent the characteristics of the new cultivar. In combination, these characteristics distinguish ‘NCIC1’ from all other varieties in commerce known to the inventor:
    • 1. Persistent, vivid yellow foliage.
    • 2. Compact, upright/rounded habit.
PARENT COMPARISONS
Table 1 compares typical characteristics of the new variety with the parent varieties.

COMMERCIAL COMPARISONS
Plants of the new cultivar ‘NCIC1’ are comparable to the patented, commercial variety Ilex ‘ANNYS1’, U.S. Plant Pat. No. 26,997. The two Ilex varieties are similar in most horticultural characteristics; however, the new variety ‘NCIC1’ differs in the following:
    • 1. Foliage of ‘NCIC1’ is more resistant to burning in sun than foliage of ‘ANNYS1’.
    • 2. Mature plants of ‘NCIC1’ are larger than mature plants of ‘ANNYS1’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
Foliage and form of ‘NCIC1’ are illustrated by the accompanying photographs. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. 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 crenata ‘NCIC1’.
FIG. 1 is a photograph showing the habit of a four-year-old field-grown plant in fall of 2021, in Mills River, NC.
FIG. 2 is a photograph of the foliage of a ten-year old field-grown plant in fall of 2022, in Mills River, NC.
