This exotic Brazilian vine requires high humidity, warm temperatures, and consistent moisture to thrive. Best grown in greenhouses or conservatories as it's sensitive to cold and dry conditions. The unusual duck-shaped flowers are fascinating but require patience as the plant can be slow to establish.
