Russian comfrey (Symphytum x uplandicum 'Bocking 14’) in P9 pot

Russian comfrey 'Bocking 14' is a vigorous, perennial plant. It differs from common comfrey in that this variety is non-invasive. Thanks to its deep roots, it extracts minerals such as potassium and nitrogen from the soil and makes them available to other plants. You can harvest the leaves multiple times per season; it grows back again and again.
