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 ‘OOSMARE1’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2015/2459, filed Oct. 26, 2015, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: Over the course of many years, the inventor sourced various Mandevilla sanderi (all non-patented) plants with flower colors ranging from white to pink to red. From this plant material, the inventor made selections of individual plants as well as single branches of individual plants, based on flower color, earliness of flowering, compactness of the plant, persistence of flowering, persistence in keeping flower color during the flowering. Many individual varieties were identified, and some were isolated for further evaluation. The candidate variety is the result of this selection process, and was first observed in the spring of 2014 in Westland, The Netherlands.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘OOSMARE1’, by way of softwood stem cuttings, was first initiated in the summer of 2014 in Westland, The Netherlands. Through more than 10 subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘OOSMARE1’ 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 ‘OOSMARE1’. These characteristics in combination distinguish ‘OOSMARE1’ as a new and distinct Mandevilla cultivar:

    • 1. Mandevilla ‘OOSMARE1’ exhibits a compact growth habit; and
    • 2. Mandevilla ‘OOSMARE1’ exhibits dark green and glossy foliage; and
    • 3. Mandevilla ‘OOSMARE1’ exhibits large bright red flowers; and
    • 4. Mandevilla ‘OOSMARE1’ exhibits continuous flowering.

BRIEF DESCRIPTION OF THE FIGURES

The FIGURE illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘OOSMARE1’ in flower, grown in a commercial greenhouse in Honselersdijk, the Netherlands.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements were made in October of 2016 and describe a mature ‘OOSMARE1’ plant grown in a greenhouse in Westland, The Netherlands. Plants were watered with overhead irrigation and fertilizer was applied using fertigation. No pest or disease measures were taken.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘OOSMARE1’ 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).
