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 ‘Inmanboclp’.

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 freely and have attractive flowers that resist fading and sun scald.

The new Mandevilla plant is a naturally-occurring whole plant mutation of Mandevilla sanderi ‘Inmanbocre’. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Inmanbocre’ in a controlled greenhouse environment in Heidesheim, Germany in June, 2017.

Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in Heidesheim, Germany since June, 2017 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 ‘Inmanboclp’. These characteristics in combination distinguish ‘Inmanboclp’ as a new and distinct Mandevilla plant:

• • 1. Compact, upright and vining plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Moderately glossy dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Light red purple-colored flowers with darker red purple-colored venation and yellow orange-colored centers.
  • 7. Relatively tolerant to low temperatures.

Plants of the new Mandevilla can be compared to plants of the mutation parent, ‘Inmanbocre’. Plants of the new Mandevilla differ primarily from plants of ‘Inmanbocre’ in flower color as plants of the new Mandevilla have light red purple-colored flowers with darker red purple-colored venation and yellow orange-colored centers whereas plants of ‘Inmanbocre’ have deep red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla sanderi ‘Inmanbochp’, disclosed in a U.S. Plant patent application Ser. No. 16/350,761 filed concurrently. Plants of the new Mandevilla differ primarily from plants of ‘Inmanbochp’ in flower color as plants of the new Mandevilla have light red purple-colored flowers with darker red purple-colored venation and yellow orange-colored centers whereas plants of ‘Imnanbochp’ have red-colored flowers with yellow orange-colored centers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Sunmandecripi’, disclosed in U.S. Plant Pat. No. 18,578. In side-by-side comparisons plants of the new Mandevilla differ primarily from plants ‘Sunmandecripi’ in the following characteristics:

• • 1. Plants of the new Mandevilla are smaller than plants of ‘Sunmandecripi’.
  • 2. Plants of the new Mandevilla have larger flowers than plants of ‘Sunmandecripi’.
  • 3. Plants of the new Mandevilla have light red purple-colored flowers with darker red purple-colored venation and yellow orange-colored centers whereas plants of ‘ Sunmandecripi’ have darker red purple-colored flowers with orange-colored centers.
