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 ‘PATMANCR’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/1474, filed Jun. 2, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘PATMANCR’ is the result of a planned breeding program. The new variety originated as a seedling from the crossing of an unnamed Mandevilla sanderi seedling developed and owned by the same inventors, the seed parent, with another unnamed Mandevilla sanderi seedling developed and owned by the same inventors, the pollen parent, in May of 2013. The crossing was made by the inventors at a greenhouse in Klazienaveen, The Netherlands. After observing the progeny of said cross, the new variety was selected in May of 2014 in Klazienaveen, The Netherlands.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘PATMANCR’, by way of softwood stem cuttings, was first initiated in June of 2014 in Klazienaveen, The Netherlands. Through more than 3 subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PATMANCR’ 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 ‘PATMANCR’. These characteristics in combination distinguish ‘PATMANCR’ as a new and distinct Mandevilla cultivar:

    • 1. Mandevilla ‘PATMANCR’ exhibits a broad, upright growth habit and broad obovate form; and
    • 2. Mandevilla ‘PATMANCR’ exhibits robust dark green foliage; and
    • 3. Mandevilla ‘PATMANCR’ exhibits an abundance of large pink flowers with a dark pink corolla tube; and
    • 4. Mandevilla ‘PATMANCR’ exhibits early flowering and a long flowering period.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary 8 month old ‘PATMANCR’ plant in a 19 cm nursery pot, grown in a greenhouse in Klazienaveen, The Netherlands.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the mature foliage of ‘PATMANCR’.

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 ‘PATMANCR’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements were made in April of 2017 and describe averages from a sample set of six specimens of 3 month old ‘PATMANCR’ 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. ‘PATMANCR’ 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).
