Dipladenia and Mandevilla, often mistaken for each other due to their striking similarities, are captivating flowering plants that can bring a touch of the tropics to any garden. While they share vibrant, trumpet-shaped flowers in shades of pink, red, and white, understanding the distinctions between them is key to successfully cultivating these botanical wonders.
Unveiling the Differences: Dipladenia vs. Mandevilla: Although both Dipladenia and Mandevilla belong to the same Mandevilla genus, they were historically classified differently based on size. Over time, nearly 200 tropical species and hybrids, including both large Mandevilla varieties and smaller Dipladenia, are now grouped together. Despite their visual similarities, subtle differences exist.
Dipladenia boasts finer, pointed, glossy green leaves, while Mandevilla plants have broader, larger leaves. Dipladenia adopts a fuller, shrub-like shape, while Mandevilla vines display a climbing tendency, reaching heights of up to 20 feet. Additionally, Dipladenia tends to have smaller flowers compared to Mandevilla.
