CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2020/1112, filed Apr. 23, 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 sanderi‘Pearl’ plants (not patented), the seed parent, and unnamedMandevilla sanderiplants (not patented) in the spring of 2017. The true pollen parent is unknown. Seed was collected from the ‘Pearl’ plants 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 unique flower color relative to the other seedlings from said cross of 2017 and was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘PATMANWHI2’, 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 ‘PATMANWHI2’ 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 ‘PATMANWHI2’. These characteristics in combination distinguish ‘PATMANWHI2’ as a new and distinctMandevillacultivar:1.Mandevilla‘PATMANWHI2’ exhibits a freely branching growth habit; and2.Mandevilla‘PATMANWHI2’ exhibits a relatively short plant height; and3.Mandevilla‘PATMANWHI2’ exhibits large flowers relative to the plant size; and4.Mandevilla‘PATMANWHI2’ exhibits flowers white flowers which do not become suffused with yellow-green when exposed to cooler temperatures; and5.Mandevilla‘PATMANWHI2’ exhibits a dark yellow inner floral tube.
