Answer: The genus Mandevilla has two distinct cultivars, one an evergreen vine and the other a deciduous vine. M 'Alice du Pont' and M. splendens are both tropical plants that can be grown outdoors in warm climates or as greenhouse or indoor plants. They are evergreen, grow 20 - 30 feet, and have twining stems with dark green, glossy leaves. They have clusters of pink flowers that appear from April to November.<br><br>Mandevilla laxa, or Chilean Jasmine is a deciduous vine with similar appearance, but is grown outdoors where it is cut back to the ground each year. The roots are hardy to about 5 degrees F. Each spring it grows from the roots, to about 15 feet, and flowers all summer.
