Thunbergia fragrans (White Clock Vine)

Thunbergia fragrans, commonly known as the White Clock Vine or Sweet Clock Vine, is a fast-growing perennial climber native to India and Southeast Asia. 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.

Thunbergia fragrans thrives in full sun to partial shade and prefers well-drained soil with regular moisture. It is suited for USDA Zones 9-11 and is not frost tolerant. 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.
