CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2020/3041, filed Nov. 27, 2020, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The new plant originated as a seedling selection from the open pollination of a plurality of cultivatedMandevilla sanderiunnamedMandevilla sanderiplants (not patented) in the spring of 2017. The true parentage of the claimed plant is unknown. Seed was collected from a plurality of these openly-pollinatedMandevilla sanderiplants and germinated at a greenhouse in Klazienaveen, The Netherlands. The resulting seedlings were grown to maturity and observed for unique characteristics. In March of 2018, the claimed plant was observed to exhibit a darker pink flower color with a narrow white petal margin, whereas the parent and other seedlings did not from said cross of 2017 and was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘PATMANROS5’, by way of softwood stem cuttings, was first initiated in March of 2018 in Klazienaveen, The Netherlands. Through more than 6 subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PATMANROS5’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PATMANROS5’. These characteristics in combination distinguish ‘PATMANROS5’ as a new and distinctMandevillacultivar:1.Mandevilla‘PATMANROS5’ exhibits an upright, freely branching growth habit; and2.Mandevilla‘PATMANROS5’ exhibits dark green, glossy foliage; and3.Mandevilla‘PATMANROS5’ exhibits very light red-purple flower buds which generally appear to be very light pink; and4.Mandevilla‘PATMANROS5’ exhibits flowers with a very light red-purple outer corolla, generally appearing as very light pink, which become progressively suffused with a darker shade of red-purple towards the apex of the petals; and5.Mandevilla‘PATMANROS5’ exhibits flowers with a red-purple inner corolla, generally appearing as deep pink, which are narrowly margined white.
