Mandevilla

Mandevilla is a genus of tropical flowering vines and shrub-like plants, many grown for trumpet-shaped flowers and glossy leaves. Species and hybrids vary widely in size, color, and growth form, so the dimensions and flowering behavior of a named selection should not be assumed for every plant in the genus. ## Form and flowering Most garden mandevillas climb or twine when given a support, while some compact cultivars remain bushier. Flowers are commonly pink, red, or white, with other colors present among particular hybrids. Many are evergreen in warm climates and bloom over an extended warm season. The genus is also sold under the familiar name Dipladenia, though that name is often applied to compact forms. ## Site Provide bright light or full sun for best flowering and use a support for vigorous climbers. In hot, humid climates, afternoon shade can reduce stress. Use a well-drained potting mix or garden soil and water when the surface begins to dry; avoid leaving roots waterlogged. Mandevillas are frost-sensitive and are usually grown outdoors year-round only in warm climates. In colder areas, container plants can be moved indoors before frost. NC State Extension notes occasional scale and mealybugs; inspect stems and leaf undersides.

Reduce watering in winter when growth slows, and check indoor plants for pests. Wear gloves if sensitive to the milky sap; avoid ingestion.
