plant named ‘Norfire’

Abstract

A new cultivar of Cordyline australis, ‘NORFIRE’, characterized by its plant habit that is dense and rounded and its numerous leaves that are short in length, narrow in width, and brown-purple in color.

Description

Botanical classification: Cordyline australis.

Cultivar designation: ‘NORFIRE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cordyline australis and will be referred to hereafter by its cultivar name, ‘NORFIRE’. ‘NORFIRE’ represents a new cultivar of cabbage tree or cabbage palm and is grown as a foliage plant for landscape and container use.

The Inventor discovered the new cultivar as a single plant in a block of young plants derived from tissue culture of Cordyline australis ‘Red Star’ (not patented) in Preston, Lancashire, United Kingdom in April of 2003.

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation in September of 2004 in Preston, Lancashire, United Kingdom under the direction of the Inventor. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. ‘NORFIRE’ exhibits foliage that is brown-purple in color.
  • 2. ‘NORFIRE’ exhibits a greater number of leaves in comparison to its parent plant.
  • 3. ‘NORFIRE’ exhibits leaves that are shorter in length and narrower in width in comparison to its parent plant and other cultivars known to the Inventor.
  • 4. ‘NORFIRE’ exhibits a plant habit that is dense and rounded.

In comparison to the parent plant, ‘Red Star’, ‘NORFIRE’ differs in having foliage that is narrower in width, shorter in length, and brown-purple rather than red-brown in color and in having a denser more rounded plant habit with a greater number of leaves. ‘NORFIRE’ can also be compared to the cultivars ‘Maroon Magic’ (U.S. Plant Pat. No. 16,954) and ‘Jel01’ (U.S. Plant Pat. No. 18,545). Both ‘Maroon Magic’ and ‘Jel01’ have similar dark brown-purple to burgundy foliage, however they both differ most significantly in comparison to ‘NORFIRE’ in having leaves that are much wider and in having a more upright plant habits.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Cordyline. The photographs were taken in March of 3 year-old plants of ‘NORFIRE’ as grown in a 25-cm container under poly cover in Preston, Lancashire, United Kingdom.

FIG. 1 provides a top view of ‘NORFIRE’ and

FIG. 2 provides a side view of ‘NORFIRE’.

FIG. 3 provides a comparison of ‘NORFIRE’ on the left and a 3 year-old plant of ‘Red Star’ on the right (planted from a 25-cm container). 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 Cordyline.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 3 year-old plants of the new cultivar as grown under poly cover in a 25-cm container in Preston, Lancashire, United Kingdom. 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
