Abstract

A new and distinct cultivar of Mandevilla plant named ‘RF AP1’, characterized by its upright to somewhat outwardly spreading plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; relatively large dark red-colored flowers; and good garden performance.

Description

Botanical designation: Mandevilla sanderi.
Cultivar denomination: ‘RF AP1’.
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 ‘RF AP1’.
The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new early flowering Mandevilla plants with large flowers and tolerance to high temperatures.
The new Mandevilla plant originated from a cross-pollination made by the Inventor in Rheinberg, Germany in May, 2007 of a proprietary selection of Mandevilla sanderi identified as code number E-Dip-06, not patented, as the female, or seed parent with a proprietary selection of Mandevilla sanderi identified as code number F-19-16, 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 Rheinberg, Germany in June, 2012.
Asexual reproduction of the new Mandevilla plant by cuttings in Rheinberg, Germany since July, 2012 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 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 ‘RF AP1’. These characteristics in combination distinguish ‘RF AP1’ as a new and distinct Mandevilla plant:
    • 1. Upright to somewhat outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Early and freely flowering habit.
    • 5. Relatively large dark red-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 flowering habit as plants of the new Mandevilla are more freely flowering than plants of the female parent selection.
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 branching habit as plants of the new Mandevilla are more freely branching than plants of the male parent selection.
Plants of the new Mandevilla can be compared to plants of Mandevilla atroviolacea×(Mandevilla amabilis×Mandevilla boliviensis) ‘Sunmandecrim’, disclosed in U.S. Plant Pat. No. 15,539. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Mandevilla differed primarily from plants of ‘Sunmandecrim’ in the following characteristics:
    • 1. Plants of the new Mandevilla were broader than plants of ‘Sunmandecrim’.
    • 2. Plants of the new Mandevilla were more vigorous than plants of ‘Sunmandecrim’.
    • 3. Plants of the new Mandevilla were more freely branching than plants of ‘Sunmandecrim’.
    • 4. Plants of the new Mandevilla had shorter internodes than plants of ‘Sunmandecrim’.
    • 5. Plants of the new Mandevilla had smaller leaves than plants of ‘Sunmandecrim’.
    • 6. Plants of the new Mandevilla and ‘Sunmandecrim’ differed slightly in flower color.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Mandevilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the following detailed botanical description which accurately describe the actual colors of the new Mandevilla plant.
The photograph comprises a side perspective view of a typical flowering plant of ‘RF AP1’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph and following observations, measurements and values describe plants grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
