BOTANICAL DESCRIPTION OF THE PLANT

(4) The following observations and measurements were made in April of 2021 and describe averages from a sample set of six specimens of 12 month-old ‘PATMANROS5’ plants grown in 17 cm nursery pots grown in a greenhouse in Klazienaveen, The Netherlands. Plants were produced using conventional greenhouse production protocols for Mandevilla which consisted of regular overhead and ebb and flood irrigation and fertigation applications. Pest or disease control measures were utilized in production as required. Plants were produced with full sun exposure and no photoperiodic treatments or artificial light was given to the plants.

(5) Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘PATMANROS5’ 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).
