Canadian vs American Ginseng: How to Tell Them Apart by Color and Texture

Canadian and American ginseng are the same family of plant, but Carmen, who runs Fosetter in Montreal's Chinatown, says you can usually tell them apart by looking. Canadian ginseng tends to be golden in color, with both horizontal rings and a tree-like grain running through the root. American ginseng is darker, and the surface only shows horizontal rings, more like the thread on a screw.

Why does the color and texture differ?

American ginseng (Panax quinquefolius) is grown across a few overlapping regions in North America, and Carmen's own stock comes from Ontario and Quebec, as well as the Wisconsin area in the US. She calls the Canadian-grown root "西洋参" and ties the name to the Atlantic coast on this side of the border, while American-grown root is "花旗参," after 花旗國, an older Chinese name for the United States. Her working rule at the counter is simple: if a root doesn't show either pattern clearly, and it also has no neck at all, "it's not 花旗参, and it's not 西洋参" — but she's careful to add that it could still be a real ginseng root grown somewhere else. She doesn't name a specific country when she says this; she just won't call it either of the two she sells.

Counting the neck to estimate age

Once you know you're holding a genuine root, there's a second question: how old is it? Carmen demonstrates with a model root at the counter, running her finger along the short knobby neck at the top. One year leaves one ring. Two years, two rings. By her count, a root at six years old carries six rings, visible one after another up the neck. It's the same scar-counting method ginseng growers use generally — our longer explainer on how the rings form and why they can be hard to read is at How to Tell a Ginseng Root's Age by Counting Neck Scars.

Color, grain, and the neck count aren't a lab test, but they're the three things Carmen actually checks before she sells a root — the same checks she walks customers through at the counter.
