plant named ‘Inmanpinli’

Abstract

A new and distinct cultivar of Mandevilla plant named ‘Inmanpinli’, characterized by its upright and vining plant habit; vigorous growth habit; freely branching habit; glossy medium green-colored leaves; freely flowering habit; and light red purple-colored flowers that resist fading.

Description

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘INMANPINLI’.

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 ‘Inmanpinli’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany and Johannesburg, South Africa. 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 originated from a cross-pollination conducted by the Inventor in Gensingen, Germany in June, 2008 of Mandevilla sanderi ‘Rio White’, not patented, as the female, or seed parent with Mandevilla sanderi ‘Rio Deep Red’, 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 Johannesburg, South Africa in December, 2009.

Asexual reproduction of the new Mandevilla plant by vegetative cuttings in a controlled greenhouse environment in Johannesburg, South Africa since March, 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 ‘Inmanpinli’. These characteristics in combination distinguish ‘Inmanpinli’ as a new and distinct Mandevilla plant:

• • 1. Upright and vining plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Glossy medium green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Light red purple-colored flowers that resist fading.

Plants of the new Mandevilla can be compared to plants of the female parent, ‘Rio White’. Plants of the new Mandevilla differ primarily from plants of ‘Rio White’ in the following characteristics:

• • 1. Plants of the new Mandevilla are more freely branching than plants of ‘Rio White’.
  • 2. Plants of the new Mandevilla flower earlier than plants of ‘Rio White’.
  • 3. Plants of the new Mandevilla and ‘Rio White’ differ in flower color as plants of ‘Rio White’ have white-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent. ‘Rio Deep Red’. Plants of the new Mandevilla differ primarily from plants of ‘Rio Deep Red’ in the following characteristics:

• • 1. Plants of the new Mandevilla are larger than plants of ‘Rio Deep Red’.
  • 2. Plants of the new Mandevilla have larger leaves than plants of ‘Rio Deep Red’.
  • 3. Plants of the new Mandevilla have larger and more open flowers than plants of ‘Rio Deep Red’.
  • 4. Plants of the new Mandevilla and ‘Rio Deep Red’ differ in flower color as flowers of plants of ‘Rio Deep Red’ have red-colored flowers.

Plants of the new Mandevilla can also be compared to plants of Mandevilla hybrida ‘Sunparapibra’, disclosed in U.S. Plant Pat. No. 19,649. In side-by-side comparisons plants of the new Mandevilla differ primarily from plants ‘Sunparapibra’ in the following characteristics:

• • 1. Flowers of plants of the new Mandevilla are larger and more open than flowers of plants of ‘Sunparapibra’.
  • 2. Plants of the new Mandevilla and ‘Sunparapibra’ differ in flower color as flowers of plants of ‘Sunparapibra’ are more reddish pink in color with darker yellow-colored throats.
