Mandevilla, a flowering sub-shrub/vine

Mandevilla is a genus of about 200 species of flowering vines that evolved in tropical and subtropical America. No part of continental U.S. is within tropical latitudes. Mandevillas are suitable for frost-free climates in cold zones 9a–12. Further north, a hard freeze will kill top growth to the ground and perhaps freeze the roots to death. These plants can be treated as annuals and replaced every spring, or be grown as container plants to be brought indoors during winter.

First described as a genus in 1840, the name honors Henry Mandeville (1773–1861), a British diplomat and gardener. Mandevilla belongs to the dogbane family, Apocynaceae. Those with smaller flowers and more compact growth habit were formerly and mistakenly called dipladenia but are now correctly identified as mandevillas
