About Cushcush yam
Dioscorea trifida, commonly known as white yam or Indian yam, is a tropical climbing plant prized for its edible tubers. It features trilobate leaves and vigorous growth, making it ideal for covering pergolas or fences in warm climates, adding an exotic and productive touch to the garden.

Care tips
It requires full sun to light partial shade for optimal tuber development. Watering should be regular and abundant during the growing season, reducing it when the leaves begin to yellow. It needs well-drained soil, rich in organic matter, and good support for climbing. A common mistake is not providing enough space or support for its vigorous growth, which can limit tuber production.
