If you ask me, The qualities that make comfrey “invasive” also makes it one of the most amazing plants around! Comfrey will
grow where other plants won’t and it gives back in a big way. It’s a plant that
I want growing everywhere on my property. I’ve currently got it planted under
fruit trees to be used as chop-n-drop nutrients and along my driveway to
help reduce erosion, increase organic matter and bring in pollinators.
