Common Hemp-Nettle (Galeopsis tetrahit) is a native annual herbaceous plant species found across the United Kingdom. Belonging to the Lamiaceae family, it is commonly encountered in a variety of habitats, including grasslands, hedgerows, woodland edges, and disturbed areas such as roadsides and waste grounds.

Common Hemp-Nettle thrives in nutrient-rich, moist soils, often favouring disturbed habitats. It is highly adaptable and can tolerate both sunny and partially shaded locations, making it a common sight in a diverse range of landscapes.

Predators of Common Hemp-Nettle include herbivores such as insects and small mammals, which may feed on its foliage or flowers. However, its hairy leaves and unpalatable taste often provide some protection from extensive browsing.

As an annual plant, Common Hemp-Nettle completes its lifecycle within one year, germinating from seeds in spring, flowering in summer, and producing seeds before dying back in autumn. It reproduces primarily via seeds, which are dispersed by wind or animals, contributing to its ability to colonise new areas.

Culturally, Common Hemp-Nettle does not hold significant symbolic or traditional references in the UK. However, it is valued for its role in supporting biodiversity and providing habitat for insects and other wildlife.

An interesting fact about Common Hemp-Nettle is its historical use as a medicinal herb, particularly in traditional European folk medicine, where it was believed to have various healing properties. Additionally, its flowers are rich in nectar and attract pollinators such as bees and butterflies, contributing to its ecological importance in British ecosystems.
