USPP19057P2 - Coprosma plant named ‘Golden Glow’ - Google Patents

Abstract

A new cultivar of Coprosma plant named ‘Golden Glow’ that is characterized by an upright habit and leaves that are green when young then turn to yellow and then to orange when mature.

Description

Botanical Classification: Coprosma.

Variety Denomination: ‘Golden Glow’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coprosma plant botanically known as Coprosma and hereinafter referred to by the cultivar name ‘Golden Glow’.

The new cultivar was discovered by the inventor in a cultivated area of Waikato, New Zealand in 2004. ‘Golden Glow’ was discovered as a naturally occurring branch mutation of Coprosma ‘Evening Glow’ (not patented).

Asexual reproduction by tip cuttings of the new cultivar ‘Golden Glow’ was first performed in 2004 in Waikato, 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 Coprosma cultivar ‘Golden Glow’.

• • 1. Coprosma ‘Golden Glow’ exhibits an upright habit.
  • 2. Coprosma ‘Golden Glow’ exhibits leaves that are lime green when young, then turn yellow, then orange when mature.

The closest comparison cultivar is the parent plant Coprosma ‘Evening Glow’. The new cultivar ‘Golden Glow’ is distinguishable from ‘Evening Glow’ by the following characteristics:

• • 1. ‘Golden Glow’ has leaves that are lime green when young, then turn yellow, then orange. The leaves of ‘Evening Glow’ are green when young, then turn orange.
  • 2. ‘Golden Glow’ has a more upright habit. ‘Evening Glow’ has a more spreading habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Coprosma ‘Golden Glow’. The plant in the photograph shows an overall view of a 12 month 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 Coprosma cultivar named ‘Golden Glow’. Data was collected in Waikato, New Zealand from 12 month old outdoor grown plants in 2.5 liter containters. The time of year was Winter and the average temperature range was 5 to 15 degrees Centigrade during the day and 2 to 8 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. ‘Golden Glow’ has not been tested under all possible conditions and phenotype differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
