Comfrey in the Garden

As a medicinal herb, comfrey (Symphytum officinale) was so prized that it was called "knitbone" and "bruisewort" as a tribute to its miraculous healing powers.

Although there are modern concerns about taking comfrey internally, it is still recommended as an external preparation for skin problems, cuts, sprains, burns, and to reduce swelling. Comfrey's leaves and root have a cornucopia of useful substances like allantoin, which encourages cell regeneration, vitamin B12, potassium, calcium, phosphorous, along with vitamins A and C, and in many countries it is used to supplement livestock feed.

Growing Comfrey

Comfrey needs full sun and nitrogen rich soil. It can send out a taproot many feet long and be very invasive if not contained. Comfrey also needs room to spread out, so place young plants at least three feet apart, and fertilize with quality manure in spring and again in late summer.

Propagating Comfrey

Propagate comfrey from sections of root that contain a growing tip or from seeds that have been chilled to approximate winter conditions.

Harvesting Comfrey

Dry leaves and flowering tops in summer and dig up comfrey roots at the end of the growing season in the fall.

Uses for Comfrey

A comfrey poultice can help speed healing, relieve aching joints, reduce swelling and inflammation, and treat skin conditions like eczema. Its high potassium content makes it a good addition to fertilizer, and it can be used to make a natural brown fabric dye.

Comfrey makes a unique and interesting fill in plant for a barren spot in the garden. It may well be the king of historical medicinal herbs, and has uses today as a home remedy. Even its appearance has nostalgic appeal. Its lavender flowers are bell shaped and delicate, contrasting well with comfrey's hairy leaves.

Give comfrey a try if you can find it at your nursery or online herb supplier; it’s a great conversation piece. Oh, and the next time you sprain your ankle maneuvering your way around your flowerbeds, grab some comfrey for the swelling and discomfort. It's the gardener's secret friend.
