Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Couriphy01’. The plants were approximately 2-years old and grown in three-gallon containers for 1 year in an outdoor nursery in West Grove, Pa.

(2) FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Couriphy01’.

(3) FIG. 2 illustrates a close-up view of a flower cluster of ‘Couriphy01’

(4) FIG. 3 illustrates a close-up view of the foliage of ‘Couriphy01’.

DETAILED BOTANICAL DESCRIPTION

(5) The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

(6) The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in October 2016 under natural light conditions in West Grove, Pa.

(7) The following descriptions and measurements describe approximately 2-year old plants produced from cuttings from stock plants and grown in an outdoor nursery under conditions comparable to those used in commercial practice. The plants were grown in West Grove, Pa. for 1 year in three-gallon containers utilizing a soilless growth medium. Measurements and numerical values represent averages of typical plants.
