Chinese Yam (Bulbils and Leaves)
New vines quickly sprout from the bulbils of Chinese yam. These drop off the vine and are carried to new locations by water or rodents or in topsoil moved for construction purposes. Even a small piece of a bulbil will sprout into a new vine, the way a small piece of a potato can create a new plant. The bulbils can overwinter and form new vines in spring.
