Ecology:

• Ubiquitous in dryish or base-rich grassland, stone walls or hedgerows
• Strongly synanthropic (tied to humanly disturbed places) in the northern third of Ireland and in areas of acid bedrock elsewhere
• Commonest in gardens and on sand dunes at the coast
• Consumed for food in southern Britain and Europe but disparaged in Ireland
