One interesting herb that we hear so little about is comfrey (Symphy-
tum officinale). This easy-to-grow perennial comes from the borage
family, has broad leaves, and it blossoms with small bell-shaped,
light-colored flowers.
It has lots of uses for the organic gardener, and also for those of us
interested in botanical medicine. Organic gardeners like comfrey be-
cause its leaves are rich in plant nutrients. As it grows and matures,
comfrey mines a host of these nutrients from the soil.
You can use the herb’s leaves as a mulch, a side-dressing, make it
into comfrey tea, or create a compost. Each method will provide
organ-ically-derived nutrients to your vegetables, flowers and land-
scape plants.
Comfrey is especially rich in potassium, an essential plant nutrient
needed for flower, fruit, and seed production. Gardeners can also use
comfrey leaves in small amounts to activate compost. Its nutrients
give a big boost to the process, helping to breakdown organic matter
into rich soil amendments.
In the world of medicine, comfrey has been known as ‘knitbone,’
because of its ability to speed up the healing of bone fractures, bruis-
ing and cuts.
However use of the herb internally is a somewhat controversial sub-
ject. The FDA warns against it due to possible liver damage.
Growing this herb is fairly easy. All you need is a nicely shaded,
well-drained location with plenty of compost and a slow-release
organic fertilizer (blood and bone meal) to give it a start. Keep it on
the moist side.
Your stand of comfrey can easily be increased by root division. Seg-
ments of these black, turnip-like roots can be cut and placed into the
soil to create new plants.
Using comfrey in this way as an organic source of plant food, along
with composting, brings the gardener yet another step closer to inde-
pendence and self-sustenance. Happy gardening everyone!
