Botanical designation: Mandevilla sanderi.
Cultivar denomination: ‘DODIPWHIHA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Dipladenia plant, commonly referred to as Mandevilla, botanically known as Mandevilla sanderi and hereinafter referred to by the name ‘Dodipwhiha’ .
The new Dipladenia plant is a product of a planned breeding program conducted by the Inventors in Rheinberg, Germany and Puerto Lumbreras, Murcia, Spain. The objective of the breeding program is to create new freely branching Dipladenia plants that flower freely and have attractive flower colors.
The new Dipladenia plant originated from a cross-pollination conducted by the Inventors in Rheinberg, Germany in September, 2020 of Mandevilla sanderi ‘Duemarhopi’, disclosed in U.S. Plant Pat. No. 24,886, as the female, or seed, parent with a proprietary breeding selection of Mandevilla sanderi identified as code number MM07-1002-049, not patented, as the male, or pollen, parent. The new Dipladenia plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Puerto Lumbreras, Murcia, Spain in September, 2021.
Asexual reproduction of the new Dipladenia plant by vegetative cuttings in a controlled greenhouse environment in Puerto Lumbreras, Murcia, Spain since November, 2021 has shown that the unique features of this new Dipladenia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Dipladenia 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 ‘Dodipwhiha’. These characteristics in combination distinguish ‘Dodipwhiha’ as a new and distinct Dipladenia plant:
- 1. Broadly upright plant habit.
- 2. Moderately vigorous growth habit and moderate growth rate.
- 3. Freely branching habit; dense and bushy appearance.
- 4. Glossy dark green-colored leaves.
- 5 Freely flowering habit.
- 6. White-colored flowers with bright yellow-colored throats.
- 7. Good garden performance.
Plants of the new Dipladenia can be compared to plants of the female parent, ‘Duemarhopi’. Plants of the new Dipladenia differ primarily from plants of ‘Duemarhopi’ in the following characteristics:
- 1. Leaves of plants of the new Dipladenia are lighter green in color than leaves of plants of ‘Duemarhopi’.
- 2. Plants of the new Dipladenia have larger flowers than plants of ‘Duemarhopi’.
- 3. Flower petals of plants of the new Dipladenia are flatter than flower petals of ‘Duemarhopi’.
- 4. Flowers of plants of the new Dipladenia are white in color whereas flowers of plants of ‘Duemarhopi’ are red purple in color.
Plants of the new Dipladenia can be compared to plants of the male parent selection. Plants of the new Dipladenia differ primarily from plants of the male parent selection in the following characteristics:
- 1. Plants of the new Dipladenia have larger leaves than plants of the male parent selection.
- 2. Plants of the new Dipladenia are more freely flowering than plants of the male parent selection.
- 3. Plants of the new Dipladenia have smaller flowers than plants of the male parent selection.
- 4. Flowers of plants of the new Dipladenia are white in color whereas flowers of plants of the male parent selection are red in color.
Plants of the new Dipladenia can also be compared to plants of Mandevilla sanderi ‘Inmanwhimp’, disclosed in U.S. Plant Pat. No. 28,276. In side-by-side comparisons, plants of the new Dipladenia differ primarily from plants ‘Inmanwhimp’ in the following characteristics:
- 1. Plants of the new Dipladenia have smaller leaves than plants of ‘Inmanwhimp’.
- 2. Plants of the new Dipladenia are more freely flowering than plants of ‘Inmanwhimp’.
- 3. Flower buds of plants of the new Dipladenia are pale purplish pink in color whereas flower buds of plants of ‘Inmanwhimp’ are pale yellowish green in color.
- 4. Plants of the new Dipladenia have smaller flowers than plants of ‘Inmanwhimp’.
- 5. Flower petals of plants of the new Dipladenia are more rounded than flowers petals of plants of ‘Inmanwhimp’.

DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 17-cm containers in a polyethylene-covered greenhouse in Puerto Lumbreras, Murcia, Spain and under cultural practices typical of commercial Dipladenia production. During the production of the plants, day temperatures averaged 21.9 C, night temperatures averaged 11.25 C and light levels averaged 650 watts/m2/h. Plants were two years old when the photographs and description were taken.
