Botanical designation:Mandevilla hybrida.

Cultivar denomination: ‘LVDIP1816’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

An European Plant Breeder's Rights application for the instant plant was filed by the Inventor/Applicant on Jun. 7, 2021, application number 2021/1469. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevillaplant, botanically known asMandevilla hybridaand hereinafter referred to by the name ‘LVDIP1816’.

The newMandevillaplant is a product of a planned breeding program conducted by the Inventor in Vacaria, Brazil. The objective of the breeding program is to develop new strong and freely floweringMandevillaplants with attractive flowers and good garden performance.

The newMandevillaplant originated from a cross-pollination in 2017 in Vacaria, Brazil ofMandevilla hybrida‘Fisrix Hopink’ (trade name, Rio Hot Pink), disclosed in U.S. Plant Pat. No. 20,672, as the female, or seed, parent withMandevilla hybrida‘Sunmandecrim’, disclosed in U.S. Plant Pat. No. 15,539, as the male, or pollen, parent. The newMandevillaplant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Vacaria, Brazil in November, 2018.

Asexual reproduction of the newMandevillaplant by terminal stein cuttings in a controlled environment in Vacaria, Brazil since January, 2019 has shown that the unique features of this newMandevillaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the newMandevillahave 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 ‘LVDIP1816’. These characteristics in combination distinguish ‘LVDIP1816’ as a new and distinctMandevillaplant:1. Upright to outwardly spreading and semi-trailing plant habit.2. Moderately vigorous to vigorous growth habit.3. Early and freely flowering habit.4. Single bright red-colored flowers that resist fading.5. Good container performance.

Plants of the newMandevillacan be compared to plants of the female parent, ‘Fisrix Hopink’. Plants of the newMandevilladiffer primarily from plants of ‘Fisrix Hopink’ in the following characteristics:1. Plants of the newMandevillahave larger flowers than plants of ‘Fisrix Hopink’.2. Plants of the newMandevillahave bright red-colored flowers whereas plants of ‘Fisrix Hopink’ have rose red to cherry red-colored flowers.

Plants of the newMandevillacan be compared to plants of the male parent, ‘Sunmandecrim’. Plants of the newMandevilladiffer primarily from plants of ‘Sunmandecrim’ in the following characteristics:1. Plants of the newMandevillaare more upright than plants of ‘Sunmandecrim’.2. Plants of the newMandevillahave lighter-colored flower throats than plants of ‘Sunmandecrim’.3. Flowers of plants of the newMandevillaresist fading with development whereas flowers of plants of ‘Sunmandecrim’ fade with development.

Plants of the newMandevillacan also be compared to plants ofMandevilla sanderi‘Fisrix Dered’, disclosed in U.S. Plant Pat. No. 20,714. In side-by-side comparisons, plants of the newMandevilladiffer primarily from plants ‘Fisrix Dered’ in the following characteristics:1. Plants of the newMandevillaare more vigorous than plants of ‘Fisrix Dered’.2. Plants of the newMandevillahave larger leaves than plants of ‘Fisrix Dered’.3. Plants of the newMandevillahave bright red-colored flowers whereas plants of ‘Fisrix Dered’ have more scarlet-colored flowers.
