Bring bold, tropical beauty to your garden with Mandevilla, a sun-loving vine prized for its large, vivid blooms and long flowering season from spring until frost. Thriving in at least six hours of direct sun, these climbers perform best in well-drained soil with consistent watering and regular fertilization to keep the flowers coming. Because they are not frost-tolerant, Mandevilla is typically grown as an annual in cooler climates or overwintered indoors. Provide a trellis or support for vertical growth, or prune lightly to encourage a fuller, bushier plant that’s just as stunning in containers as it is in the landscape.
