Green Alkanet (Pentaglottis sempervirens) is a perennial herbaceous plant native to the United Kingdom, belonging to the Boraginaceae family. It is commonly found in hedgerows, woodlands, and disturbed habitats throughout the UK.

Green Alkanet thrives in nutrient-rich, well-drained soils, often favouring habitats with partial shade or dappled sunlight. It can tolerate a wide range of soil types, including loam, clay, and sandy soils, making it adaptable to various environmental conditions.

Predators of Green Alkanet include herbivores such as grazing mammals and insects, which may feed on its foliage. However, its rough leaves and hairy texture often provide some protection from extensive browsing.

As a perennial plant, Green Alkanet can live for several years, forming dense clumps of coarse, hairy leaves and producing clusters of small, bright blue flowers in spring to early summer. It reproduces via seeds, which are dispersed by wind or animals.

Culturally, Green Alkanet does not hold significant symbolic or traditional references in the UK. However, it is valued as an ornamental plant in gardens and landscapes, where it adds a splash of vibrant colour to borders and wildflower meadows.

An interesting fact about Green Alkanet is its historical use as a dye plant. The roots contain a red dye known as alkannin, which was traditionally used to dye fabrics and textiles. Additionally, the leaves and flowers have been used in herbal medicine for their purported medicinal properties, although their efficacy is not well-documented.
