Title: Mandevilla plant named ‘Inmanbered’

Description:
Botanical designation:  Mandevilla sanderi.    
     Cultivar denomination: ‘INMANBERED’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Mandevilla  plant, botanically known as  Mandevilla sanderi  and hereinafter referred to by the name ‘Inmanbered’. 
     The new  Mandevilla  plant is a product of a planned breeding program conducted by the Inventor in Johannesburg, South Africa and Heidesheim, Germany. The objective of the breeding program is to create new freely branching  Mandevilla  plants that flower early and freely and have attractive flowers that resist fading and sun scald. 
     The new  Mandevilla  plant originated from a cross-pollination conducted by the Inventor in Johannesburg, South Africa in January, 2014 of a proprietary selection of  Mandevilla sanderi  identified as code number D11-2179-1, not patented, as the female, or seed parent with a proprietary selection of  Mandevilla sanderi  identified as code number D11-2097-1, not patented, as the male, or pollen, parent. The new  Mandevilla  plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany in June, 2015. 
     Asexual reproduction of the new  Mandevilla  plant by vegetative cuttings in a controlled greenhouse environment in Heidesheim, Germany since August, 2015 has shown that the unique features of this new  Mandevilla  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Mandevilla  have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature 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 ‘Inmanbered’. These characteristics in combination distinguish ‘Inmanbered’ as a new and distinct  Mandevilla  plant:
         1. Broadly upright and vining plant habit.   2. Moderately vigorous growth habit.   3. Freely branching habit.   4. Glossy dark green-colored leaves.   5. Early and freely flowering habit.   6. Deep red-colored flowers with orange-colored centers that resist fading.   7. Relatively tolerant to low temperatures.       

     Plants of the new  Mandevilla  can be compared to plants of the female parent selection. Plants of the new  Mandevilla  differ primarily from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Mandevilla  have smaller leaves than plants of the female parent selection.   2. Plants of the new  Mandevilla  have deep red-colored flowers whereas plants of the female parent selection have light pink-colored flowers.       

     Plants of the new  Mandevilla  can be compared to plants of the male parent selection. Plants of the new  Mandevilla  differ primarily from plants of the male parent selection in the following characteristics:
         1. Plants of the new  Mandevilla  are larger than plants of the male parent selection.   2. Plants of the new  Mandevilla  have stronger roots than plants of the male parent selection.   3. Plants of the new  Mandevilla  have deep red-colored flowers whereas plants of the male parent selection have pink-colored flowers.       

     Plants of the new  Mandevilla  can also be compared to plants of  Mandevilla hybrida  ‘Inmanredeep’, disclosed in U.S. Plant Pat. No. 29,096. In side-by-side comparisons, plants of the new  Mandevilla  differ primarily from plants ‘Inmanredeep’ in the following characteristics:
         1. Plants of the new  Mandevilla  are more upright than plants of ‘Inmanredeep’.   2. Plants of the new  Mandevilla  are not as freely branching as plants of ‘Inmanredeep’.   3. Plants of the new  Mandevilla  have thicker and stronger stems than plants of ‘Inmanredeep’.   4. Plants of the new  Mandevilla  have longer leaves than plants of ‘Inmanredeep’.   5. Flowers of plants of the new  Mandevilla  are slightly darker red than flowers of plants of ‘Inmanredeep’.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring in 12-cm containers in a glass-covered greenhouse in Heidesheim, Germany and under cultural practices typical of commercial  Mandevilla  production. During the production of the plants, day temperatures ranged from 12° C. to 35° C. and night temperatures ranged from 12° C. to 18° C. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
