Strongly fragrant and vigorous, Mandevilla laxa (Chilean Jasmine) is a semi-evergreen, woody, twining climber with sprays of 3-15 large, creamy-white, funnel-shaped flowers, up to 3 in. across (8 cm), with broad petal lobes. The blossoms release a sweet vanilla fragrance that is most pronounced in the evening. Blooming periodically in summer, the blossoms contrast against the lush foliage of oval, shiny bright green leaves, 4 in. long (10 cm). The flowers give way to pairs of long bean-like fruit pods. Evergreen in warm climates.
