About Chinese Yam

Chinese Yam is a super rare houseplant 🌿 that needs regular watering to thrive. They do best in long-lasting, direct light ☀️ and should be less than 1 foot from a window.

Chinese Yam belongs to the Dioscorea genus, and is native to Central and South China and Kuril Islands to Taiwan.

⚠️ Chinese Yam is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.
