USPP19257P3 - Corokia plant named ‘Phantom’ - Google Patents

Abstract

A new cultivar of Corokia plant named ‘Phantom’ that is characterized by narrow leaves that are colored dark brown on the upper surface and vigorous growth.

Description

Botanical Classification: Corokia virgata. Variety Denomination: ‘Phantom’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Corokia plant botanically known as Corokia virgata and hereinafter referred to by the cultivar name ‘Phantom’.

The new cultivar originated from a cross of the male or pollen parent plant an unidentified cultivar of Corokia virgata and the female or seed parent plant an unidentified cultivar of Corokia virgata. ‘Phantom’ was selected as a single plant from the progeny of the stated cross by the inventor in a cultivated area of Auckland, New Zealand in 2004.

Asexual reproduction by terminal cuttings of the new cultivar ‘Phantom’ was first performed in 2004 in Auckland, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Corokia cultivar ‘Phantom’.

• • 1. Corokia ‘Phantom’ exhibits leaves that are colored dark brown on the upper surface.
  • 2. Corokia ‘Phantom’ exhibits vigorous growth.
  • 3. Corokia ‘Phantom’ exhibits narrow leaves.

The closest comparison cultivar is Corokia ‘Frosted Chocolate’.

The new cultivar ‘Phantom’ is distinguishable from ‘Frosted Chocolate’ unpatented by the following characteristics:

• • 1. ‘Phantom’ has leaves that are brown on the upper side. The upper leaves of ‘Frosted Chocolate’ are grey-orange.
  • 2. ‘Phantom’ has narrower leaves than the leaves of ‘Frosted Chocolate’.
  • 3. ‘Phantom’ has shorter leaves than the leaves of ‘Frosted Chocolate’.
  • 4. ‘Phantom’ has a longer internode length.

The new cultivar ‘Phantom’ is distinguishable from the parent plants by the following characteristics:

• • 1. ‘Phantom’ has leaves that are brown on the upper side. The upper leaves of the parent plants are green.
  • 2. ‘Phantom’ has narrower leaves.
  • 3. ‘Phantom’ has shorter leaves.
  • 4. ‘Phantom’ has a longer internode length.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Corokia ‘Phantom’. The plant in the photograph shows an overall view of a 1 year old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Corokia cultivar named ‘Phantom’. Data was collected in Auckland, New Zealand from 1 year old plants grown outdoors in 3.3 liter containers. The time of year was Winter in the Southern Hemisphere and the temperature range was 12 to 18 degrees Centigrade during the day and 4 to 11 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Phantom’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
