Description

DETAILED BOTANICAL DESCRIPTION

[0022] 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.

[0023] 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 July 2019 under natural light conditions in West Chicago, Ill.

[0024] The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown as three plants per pot in one-gallon containers for approximately 17 weeks in a greenhouse in Elburn, Ill. Greenhouse temperatures were maintained at approximately 60 F. to 65 F. (15.5 C. to 18,3 C.) during the day and approximately 55 F. to 60 F. (12.7 C. to 15.5 C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants. [0025] Botanical classification: Achillea millefolium FLORACHRO1.
