BOTANICAL DESCRIPTION OF THE PLANT

(4) The following observations and measurements made in August of 2017 describe averages from a sample set of six specimens of 18 month-old DURAMIA plants grown in 9 cm nursery pots at a commercial greenhouse in Evergem, Belgium. Plants were grown under light maximum light levels of approximately 12,000 lux. Plants were maintained with a fertigation program and regularly watered with overhead irrigation. No chemical pest measures were taken.

(5) Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. DURAMIA has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
