Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Mandevilla sanderi (Hemsl.) Woodson.

Variety denomination: The inventive variety of Mandevilla disclosed herein has been given the variety denomination ‘PATMANROS5’.

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 cultivated Mandevilla sanderi unnamed Mandevilla sanderi plants (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-pollinated Mandevilla sanderi 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 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 distinct Mandevilla cultivar:

    • 1. Mandevilla ‘PATMANROS5’ exhibits an upright, freely branching growth habit; and
    • 2. Mandevilla ‘PATMANROS5’ exhibits dark green, glossy foliage; and
    • 3. Mandevilla ‘PATMANROS5’ exhibits very light red-purple flower buds which generally appear to be very light pink; and
    • 4. 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; and
    • 5. Mandevilla ‘PATMANROS5’ exhibits flowers with a red-purple inner corolla, generally appearing as deep pink, which are narrowly margined white.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary flower of ‘PATMANROS5’.

 BOTANICAL DESCRIPTION OF THE PLANT

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.

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).
