Overview
Wood betony (Stachys officinalis) is a mint-family perennial that forms tidy rosettes of textured foliage topped by dense spikes of magenta to purple blooms in summer.
In medieval times it was considered an almost magical cure-all, planted in monastery and churchyard gardens. Today it is grown both as a reliable border plant and as a traditional medicinal herb. It should not be confused with the unrelated lousewort betonies (Pedicularis).
How to identify it
- Foliage: Oblong, deeply veined, scallop-edged leaves forming a basal rosette
- Flowers: Dense, interrupted spikes of two-lipped reddish-purple to magenta flowers
- Habit: Clumping perennial 1-2 ft tall in bloom
- Stems: Square stems typical of the mint family, but the plant is only faintly aromatic
- Bloom time: Early to midsummer
Care & growing
Light: Full sun to partial shade.
Water: Prefers consistently moist but well-drained soil; tolerates some drought once established.
Soil: Average to humus-rich, well-drained soil.
Temperature: Hardy to USDA zone 4.
Feeding: Minimal; an annual compost topdressing suffices.
Propagation: Divide clumps in spring or fall, or sow seed. Deadhead to prolong bloom.
Habitat & origin
Wood betony is native to Europe, western Asia, and North Africa, where it grows in meadows, open woodlands, grassy heaths, and hedgerows.
It is widely cultivated in cottage gardens, pollinator borders, and naturalistic plantings across temperate regions.
Uses & benefits
- Ornamental: Long-blooming, low-maintenance border and meadow plant
- Ecological: A magnet for bees, butterflies, and other pollinators
- Medicinal (traditional): Historically used for headaches, nerves, and digestion; still used in herbalism as a mild relaxant
- Cultural: Once planted to ward off evil and protect homes in folk tradition
