The vine performs best in warm climates with ample sunlight and consistent moisture but does not tolerate waterlogged soils. Once established, it thrives with minimal care but benefits from occasional pruning to maintain shape and encourage more blooms. It can be grown annually or in overwintered indoor containers in frost-prone areas. The flowers are a visual delight and emit a sweet scent, especially in the evening, enhancing its appeal in gardens or patios.

This vine is a standout choice for tropical or exotic-themed gardens, creating an eye-catching focal point while supporting pollinators with its showy and fragrant blooms.
