plant named ‘Land Green’

Abstract

A new cultivar of Ilex crenata plant named ‘Land Green’ that is characterized by its pyramidal plant shape that requires little pruning to maintain a pyrimidal shape, its leaves that are dark green in color and its compact plant habit.

Description

Botanical classification: Ilex crenata.

Variety denomination: ‘Land Green’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is related to a European plant breeders' rights application filed on Jul. 17, 2019, application No. 2019/1745. There have been no offers for sale anywhere in the world more than one year prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.

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, ‘Land Green’. ‘Land Green’ is a new cultivar of Japanese holly grown for use as an ornamental landscape plant.

‘Land Green’ was discovered by the Inventor as a chance seedling in a trial field in Pontevedra, Spain in June of 2009. The parentage is unknown as there were numerous cultivars of Ilex crenata growing in the field including ‘Fastigiate’, ‘Golden Gem’, ‘Green Gem’, and ‘Stokes’ (all unpatented).

Asexual propagation of the new cultivar was first accomplished by one of the Inventors using softwood stem cuttings in July of 2014 in Pontevedra, Spain. Asexual propagation by softwood 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 ‘Land Green’ as a unique cultivar of Ilex.

• • 1. ‘Land Green’ exhibits a pyramidal plant shape that requires little pruning to maintain a pyrimidal shape.
  • 2. ‘Land Green’ exhibits leaves that are dark green in color.
  • 3. ‘Land Green’ exhibits a compact plant habit.

‘Land Green’ can be most closely compared to the Ilex crenata cultivars ‘Convexa’ (not patented) and ‘Stokes’ (not patented). ‘Convexa’ is similar to ‘Land Green’ in having dark green foliage. ‘Convexa’ differs from ‘Land Green’ in having a less pyramidal plant shape, a less compact plant habit, leaves that are more convexed in aspect, and in requiring more pruning to maintain a pyrimidal shape. ‘Stokes’ is similar to ‘Land Green’ in leaf shape. ‘Stokes’ differs from ‘Land Green’ in having a less pyramidal plant shape, a less compact plant habit, and a more vigorous growth rate.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of a six-month-old plant of the new cultivar as grown outdoors in a 9-cm container (planted with 2 plugs) in Boskoop, The Netherlands.

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

The photograph in FIG. 2 provides a close-up view of the foliage of ‘Land Green’.

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 six-month-old plants of the new cultivar grown in a conventional greenhouse in 9-cm containers (planted with 2 plugs) in Boskoop, The Netherlands. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
