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 ‘Dreamnuflor3512’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia. The objective of the breeding program is to create new Mandevilla plants that flower for a long period of time and have large attractive flowers.

The new Mandevilla plant originated from a cross-pollination made by the Inventor in Cobbitty, New South Wales, Australia in February, 2009 of a proprietary selection of Mandevilla hybrida identified as code number DIP 799, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number DIP 7100, 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 Cobbitty, New South Wales, Australia in May, 2010.

Asexual reproduction of the new Mandevilla plant by cuttings in Macquarie Fields, New South Wales, Australia since May, 2010 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 ‘Dreamnuflor3512’. These characteristics in combination distinguish ‘Dreamnuflor3512’ as a new and distinct Mandevilla plant:

• • 1. Upright and somewhat vining to climbing plant habit.
  • 2. Vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Long flowering period.
  • 5. Dark pink-colored flowers.
  • 6. Good garden performance.

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. Leaves of plants of the new Mandevilla are smooth and glabrous whereas leaves of plants of the female parent selection are pubescent.
  • 3. Plants of the new Mandevilla and the female parent selection differ in flower color as plants of the female parent selection have pale 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 have larger leaves than plants of the male parent selection.
  • 2. Plants of the new Mandevilla and the male parent selection differ in flower color as plants of the male parent selection have red-colored flowers.

Plants of the new Mandevilla can be compared to plants of ‘Dreamnuflor3513’, disclosed in U.S. Plant patent application Ser. No. 14/121,806, filed concurrently. Plants of the new Mandevilla and ‘Dreamnuflor3513’ differ primarily in flower color as plants of ‘Dreamnuflor3513’ have bright red-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevilla hybrida ‘White Fantasy’, not patented. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Mandevilla differed primarily from plants of ‘White Fantasy’ in the following characteristics:

• • 1. Plants of the new Mandevilla had smaller leaves than plants of ‘White Fantasy’.
  • 2. Leaves of plants of the new Mandevilla were smooth and glabrous whereas leaves of plants of ‘White Fantasy’ were pubescent.
  • 3. Plants of the new Mandevilla and ‘White Fantasy’ differed in flower color as plants of ‘White Fantasy’ had white-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Crimson Fantasy’, not patented. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Mandevilla differed primarily from plants of ‘Crimson Fantasy’ in the following characteristics:

• • 1. Plants of the new Mandevilla had smaller leaves than plants of ‘Crimson Fantasy’.
  • 2. Leaves of plants of the new Mandevilla were smooth and glabrous whereas leaves of plants of ‘Crimson Fantasy’ were pubescent.
  • 3. Plants of the new Mandevilla and ‘Crimson Fantasy’ differed in flower color as plants of ‘Crimson Fantasy’ had crimson-colored flowers.
