Looking to add a vertical element with nonstop color to your container garden this year? Try a Mandevilla.

Often confused with Bougainvillea, Mandevilla blooms are more trumpet-shaped, and the veins on its leathery leaves are more pronounced. This woody vine is native to parts of South America, so it’s often treated as an annual in any USDA Zone less than 9. However, it may be brought inside and treated as a houseplant to overwinter in those colder zones.

Beautiful Mandevilla

Mandevilla blooms in white, pink, red, and yellow, with the pink variety Alice du Pont being one of the most popular and commonly available (and a Hummingbird magnet).

Plants will happily climb a trellis or post and also look great spilling over the edge of a hanging basket. Typically, a Mandevilla will put out 3-5 feet of growth in one season, but may grow as much as 10 feet. For prolific and continuous blooms, feed every other week with a balanced water-soluble fertilizer like 20-20-20.

Mandevilla can be grown in full or part sun, and they appreciate afternoon shade in hot climates. Mandevilla are drought tolerant once established, but will bloom more consistently if the soil is kept moist (not soggy). They are also salt tolerant, which makes them a great candidate for coastal gardens.

Growing Mandevilla Indoors

For those of us who live in colder climates, Mandevilla can be brought inside to overwinter. Plants may be trimmed back lightly if needed and placed near the brightest available window. Don’t worry if leaves turn yellow and fall off. This is normal, and the plant will push out new growth within a few weeks.

Be sure not to overwater during this time. Stop feeding Mandevilla in winter months and only water when the soil is dry to the touch. Resume feeding and increase water a few weeks before your last frost date.

Mandevilla generally don’t have many issues with pests, but keep an eye out for spider mites, mealybugs, and whiteflies, especially on plants overwintered indoors. A simple insecticidal soap spray should take care of any infestation.
