Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The accompanying photograph illustrates the distinguishing traits of Coprosma NGCOP8. The plant in the photograph shows an overall view of a 12 month old plant.

(2) 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

(3) The following is a detailed description of the new Coprosma cultivar named NGCOP8. Data was collected in Grand Haven, Mich. from 12 month old greenhouse grown plants in one gallon containers. The plants were grown under natural light. The time of year was Summer and the average temperature range was 18 to 27 degrees Centigrade during the day and 5 to 10 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2015 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. NGCOP8 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.
