Comphrey is a great herb for the garden and is easy to grow. Comphrey has black, thick roots (looks like a root vegetable) and large, broad, hairy, green leaves. It has small bell-shaped flowers.
Comphrey grows readily from seedling or cutting. It prefers well-manured soil but seems happy pretty much anywhere.
It grows in full or partial sun and can be planted under trees. If you plant it directly into the garden it will spread around at a surprising pace. It can be difficult to get rid of – be warned.
Comphrey can be used as a medicinal herb, and is a wonderful green-manure plant/compost ingredient.
