It produces twining stems with triangular to heart-shaped leaves and delicate white funnel-shaped flowers with a yellow throat, usually blooming throughout the warm season. This species is often used as a quick cover for fences, trellises, and arbors, where it adds a light and airy appearance to the garden.

The vine is best grown in warm climates or containers that can be moved indoors during colder months. Protect from frost at all times, as prolonged exposure to temperatures below 40F may damage the plant.
