Selfheal (Prunella vulgaris) is a perennial herbaceous plant native to the United Kingdom, belonging to the Lamiaceae family. It is commonly found in grasslands, meadows, woodlands, and disturbed areas throughout the UK.

Selfheal thrives in nutrient-rich, well-drained soils and can tolerate a range of soil types, including loam, clay, and sandy soils. It prefers habitats with partial shade to full sun, often growing in open grassy areas or along woodland edges.

As a perennial plant, Selfheal forms low-growing rosettes of toothed leaves and produces spikes of small purple flowers in summer. These flowers are attractive to pollinators such as bees, butterflies, and hoverflies.

Predators of Selfheal include herbivores such as grazing mammals and insects, which may feed on its foliage and flowers. However, its bitter-tasting leaves and toxic compounds often provide some protection from extensive browsing.

Culturally, Selfheal holds some traditional and medicinal significance in the UK. In the past, Selfheal was used in traditional herbal medicine to treat various ailments, including sore throats, wounds, and gastrointestinal issues. Additionally, it has been associated with folklore and superstitions, often symbolising healing and protection.

An interesting fact about Selfheal is its ability to spread rapidly and colonise bare ground, forming dense mats of vegetation. It is also known for its resilience and ability to tolerate a wide range of environmental conditions, making it a common sight in both urban and rural landscapes across the UK.
