"Well, it won't grow in the sun. And it don't like limestone much, so if you are in hickory trees, or red cedar, you're in the wrong place. It likes big yaller poplar, or they like the same things- deep dirt, north faces, northeast faces, sometimes east, I guess, if ever'thing else is in place. You can tell you're gettin' close because you'll see spice bush, and cohosh growing, sometimes Solomon's Seal and goldenseal. Them red berries on Jack in the Pulpit will fool you, but if you're seein' them, you might want to look closer, 'cause that's a shade- and deep-dirt plant like ginseng, and sometimes they'll grow together. If you are in a lot of poison ivy, that means somebody logged that place or let the light in for some reason, and you won't find ginseng there, usually. Maybe it was there, but it's not anymore. And remember, if you're on some old hot rocky ridge, maybe a west-running ridge, some pocket of it has to face north, and you might go down on that side and find a patch that nobody's ever thought would be there."
