A plant perspective on the herbalist work

In my dream last night, I was walking with an old friend. We were making our way through overgrown meadows, along a stream that drained a big pond. A thicket of small trees and sumac came up on the left, and my friend walked in, all of a sudden very excited. He called to me to follow. He was looking for a plant he'd seen there, one he wanted to show me, one he was thrilled to have found. In that state of semi-lucidity so often encountered in dreams, I though to myself "ooh, a plant dream. This is going to be good." I got a little excited too. He pulled some brush aside, and there, in moist rich soil a few feet from the stream, was a tiny burdock plant. I remember looking at him like "you've got to be kidding me."
He proceeded to tell me all about how he'd been waiting so long for burdock to return to this land, how wonderful and special a plant it is, how it digs deep magic out of the hardest places, how it brings just the right kind of moisture to the skin. I wasn't too impressed, but I indulged him - after all, he was an old friend I hadn't seen in a long, long time, and he was apparently talking about an old friend of his that he hadn't seen in a long, long time either...
