Prunella vulgaris - Selfheal
Prunella vulgaris - Selfheal, is a 5–30 cm high creeping grassland perennial with a square stem and bright green oval leaves, borne in opposite pairs. The flowers are violet, hooded and two lipped and are arranged into a dense slightly oblong head. Flowering is from June to September.
Selfheal is found on a wide range of grasslands such as meadows, pasture, lawns, roadsides and woodland clearings but has a particular affinity for moist, moderately fertile neutral or calcareous soils. A short rather slow growing plant it is often dominated by taller vegetation but can persist due to its tolerance of moderate shade.
It is particularly attractive to bees.
