Mandevilla, also known as rock trumpet, is a genus of flowering vines that grow in tropical and subtropical climates. The five-petal flowers are often showy and fragrant, typically coming in shades of pink, red, and white, occasionally with yellow throats. They generally bloom in summer and can stretch into fall, though in warm climates they can bloom year-round. Some species within the genus have smaller, more plentiful blooms while others have fewer, larger blooms. Their foliage is usually a glossy green.
Within their USDA growing zones, Mandevilla plants can be grown as perennials; gardeners outside of their zones often like to grow them as annuals, especially in containers. These fast-growing vines should be planted in mid-to-late spring once the temperature is reliably warm and the risk of frost has passed.
