Or root hairs! I dug up some comfrey one year to send to someone, and I potted up the extra root hairs. They grew into plants.
My main plant is next to a hose bib and started spreading only after I took out the nearby raspberry patch. But whenever I put my hand in the soil to dig up a few pieces of root, it's kind of scary: the soil is loaded with thick roots.
