Planting and care
I first encountered wild yam on a walk around what became the North American Native Plant Society nature reserve, the Shining Tree Woods, in autumn 12 years ago. Next spring that vine had many seeds, and I received permission to take a few.
The seed of wild yam will germinate readily. When you start your plants, you will find that within a few years they will spread by both a more robust root system (which is like five-millimetre or two-tenths of an inch-thick pasta, interconnected versus discrete, and a dark reddish colour) and new shoots from these roots, or by seeds being dispersed by wind and creatures.
