Snail Vine (Vigna caracalla, syn. Cochliasanthus caracalla) is a beautiful, fast-growing vine with unique spiral-shaped flowers that resemble a snail’s shell. Native to tropical and subtropical regions, this plant thrives in warm climates and is often grown as an annual in cooler areas.
In warmer areas the plant will flower almost year round.
What Is Vigna caracalla?
Also known as Corkscrew Vine or Snail Creeper, Vigna caracalla features fragrant flowers that twist into elegant spirals. These blooms range in color from creamy green to soft mauve and pale pink. Ants are often drawn to the flowers, helping with pollination and seed pod formation.
It is the shape of the flower that gives the plant its name, they spiral like a snails shell. The flowers are followed by seed pods if the appropriate pollinators are around, and these are ants that are attracted to the flowers.
Growing Conditions
As the plant grows in late spring to summer it needs to be pruned back to encourage good flower formation. This is not a problem as this is a fast growing plant and it recovers quickly. We think the height should be restricted to around 2 metres at the most.
- Light: Full sun in a warm, sheltered spot
- Soil: Rich, moist, and well-draining
- Water: Keep soil moist during the growing season
- Fertilizer: Use a liquid fertilizer every few weeks
- Climate: Tropical and subtropical areas preferred; treat as annual in cold climates
This versatile vine can also thrive in containers, making it great for patios and balconies.
Pruning
