Our Comfrey is Bocking 14 (or Russian Comfrey), a Sterile (does not self-seed) deep-rooted perennial herb known for its ability to improve soil health and support garden ecosystems. Its deep taproots mine nutrients from the subsoil, bringing them to the surface, making comfrey an excellent natural fertiliser. The leaves are commonly used as "green manure," compost activators, or mulch around other plants to promote growth. This Comfrey only spreads via the roots.
Comfrey also has a long history of medicinal use in traditional remedies for skin healing and reducing inflammation, although internal use is now discouraged due to its pyrrolizidine alkaloid content.
Comfrey pairs well with fruit trees, tomatoes, and potatoes, providing a boost to their growth while improving soil structure and retaining moisture.
The package has ~2-5 roots.
Where Can You Grow Comfrey
Comfrey thrives in a wide range of climates, including Zones 3-9. It prefers well-draining soil and full sun but can tolerate partial shade. Once established, it is drought-resistant and can grow vigorously, even in less-than-ideal conditions.
History and Historical Uses
Comfrey has been used for centuries, both in agriculture and medicine. Originating in Europe and Asia, it was traditionally referred to as "knitbone" due to its use in poultices to aid in bone healing and wound care. In modern gardening, it is prized for its regenerative properties and role in permaculture systems.
