Description

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPA 13872’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT and ASSIGNEE

The Inventor/Applicant and Assignee assert that no sales, offers for sale or public distribution of the instant plant occurred more than one year prior to the effective filing date of this application.

Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant and/or Assignee. Inventor/Applicant and Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosures and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunpa 13872’.

The new Mandevilla plant is a naturally-occurring branch mutation of Mandevilla hybrida ‘Sunpa 201’, disclosed in U.S. Plant Pat. No. 34,565. The new Mandevilla plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘Sunpa 210’ in a controlled greenhouse environment in Maasland, The Netherlands in June 2022.

Asexual reproduction of the new Mandevilla plant by terminal vegetative cuttings in Maasland, The Netherlands since June 2022 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 ‘Sunpa 13872’. These characteristics in combination distinguish ‘Sunpa 13872’ as a new and distinct Mandevilla plant:

• • 1. Vining and climbing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. Flowers that are purplish red and light purplish pink bi-colored.
  • 7. Good garden performance.

Plants of the new Mandevilla can be compared to plants of the mutation parent, ‘Sunpa 201’. Plants of the new Mandevilla differ primarily from plants of ‘Sunpa 201’ in flower color as plants of the new Mandevilla have purplish red and light purplish pink bi-colored flowers whereas plants of ‘Sunpa 201’ have speckled red and light purplish pink bi-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla hybrida ‘Sunpa 4411’, disclosed in U.S. Plant Pat. No. 33,141. In side-by-side comparisons, plants of the new Mandevilla differ from plants of ‘Sunpa 4411’ in the following characteristics:

• • 1. Plants of the new Mandevilla have smaller leaves than plants of ‘Sunpa 4411’.
  • 2. Plants of the new Mandevilla have larger flowers than plants of ‘Sunpa 4411’.
  • 3. Flowers of plants of the new Mandevilla face more outwardly than and not as upright as flowers of plants of ‘Sunpa 4411’.
  • 4. Flower petals of plants of the new Mandevilla are imbricate whereas flower petals of plants of ‘Sunpa 4411’ are not imbricate.
  • 5. Plants of the new Mandevilla have purplish red and light purplish pink bi-colored flowers with purplish red-colored throats whereas plants of ‘Sunpa 411’ have purplish red-colored flowers with yellow-colored throats.
  • 6. Plants of the new Mandevilla have shorter peduncles than plants of ‘Sunpa 4411’.
