Self-Heal (Prunella Vulgaris): A Small but Versatile Garden Plant

Scientific Identity

Self-heal's scientific name is Prunella vulgaris, part of the mint family (Lamiaceae). Its common name comes from exactly this trait, traditionally thought to help wounds heal. As seen in the photo, it has small, purple-blue flowers opening in a tight, cone-like head.

Permaculture Value

Self-heal is another one of the self-seeding plants in my garden. It has a low, ground-cover-like habit that helps protect the soil surface and reduce moisture loss. Its flowers are an important source for bees, and being tolerant of mowing even in lawn areas makes it a low-maintenance choice.

Edible / Medicinal Properties

As its name suggests, self-heal is one of the oldest known plants in traditional medicine, used in folk healing across both Europe and East Asia. Its leaves have traditionally been used as a natural aid for small cuts and irritations, and its flowering stems as a gargle for sore throats. Young leaves can be eaten fresh in salads or lightly cooked. These are traditional uses, and I'd recommend consulting a professional for any actual health concern.

How to Grow It

Self-heal needs almost no special care. It grows readily in sun or partial shade, in most soil types, and tolerates significant drought well. Once established it self-seeds and spreads on its own, and if left alone it can cover a fairly wide area in a short time.

From the Garden

I see this plant in several different corners of my garden, I never planted any of it, it just comes up on its own. Its small purple flowers create a nice texture across ground-covered areas. Getting such a versatile plant with this little effort is exactly what a permaculture garden is meant to be about.
