How to grow self-heal (Prunella vulgaris)

Part of the mint family (Lamiaceae), self heal (or all-heal and heal-all) has long been used for its medicinal qualities – the leaves are reputed to heal wounds when applied to them. The plant has many other names too, including blue curls, blue Lucy and thimble flower.

In the garden, self heal can be grown as part of a wildflower patch or wildflower lawn, at the front of a border, or used as ground cover. It self-seeds easily so if not deadheaded, it will spread. The flowers are extremely attractive to bees and other insects.

How to grow self heal

Grow self heal in moist but well-drained soil, in sun or partial shade. It does best when surrounded by other low-growing plants and grows extremely well in lawns. Ensure that it's not smothered by taller plants, cutting them back at the end of the season. Deadhead after flowering if you want to stop self heal spreading – it self-seeds readily.

Self-heal is one of our recommended 11 wildflowers for shade and is fantastic incorporated into alternative lawn mixes.

Where to grow self heal

Grow self heal in full sun or partial shade, in any moist, well-drained soil. Grow with other low-growing plants, as it can be dominated by taller ones. Cut any taller plants around it back at the end of the season. Self heal is particularly suited to growing in a wildflower lawn.

How to plant self heal

Plant self heal plants or plugs in spring, around 30cm apart. Dig a hole the same size as the rootball, pop the plant in and back fill, firming around the plant. Water in well.

Caring for self heal

Deadhead self heal as soon as it's finished flowering if you don't want it to self-seed – it can spread easily.

How to propagate self heal

You can save seed from your existing plants in autumn, or buy seed online. Sow seeds in a tray in a cold frame in spring, or sow direct where you want the plants to flower in late spring, 2mm deep. Germination is slow and can take up to eight weeks. If sown in a cold frame, transplant seedlings when they're large enough to handle, into 9cm pots, and grow on before planting out in late spring. If you have sown the seeds direct, thin the seedlings to 30cm apart.

You can also divide self heal plants in spring.
