is a mandevilla perennial
Mandevillas grow as tropical perennials in frost-free regions. When looking for an attractive, blooming tropical vine, don't overlook mandevillas (Mandevilla spp.). These lovely climbing vines have abundant and showy blossoms that are produced for a period of several months.n these areas, mandevilla vines can reach a height of 10 to 20 feet, with older stems becoming woody and thick. In parts of zone 8 where winter frosts might occur, mandevillas planted outdoors often die back to the ground but regrow from surviving roots the next spring.
