Selfheal also known as allheal or Heal-all is a short, 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. It loves lawns and will stick close to the ground in order to survive even the closest mowing – it will even flower on 3cm-high flower spikes to ensure survival of its species. It spreads by seeds from its flowers (June to November) which are loved by butterflies and bees.
