Willowherb is a common name for various species of flowering plants in the genus Epilobium. These plants are typically found in temperate regions and are known for their vibrant pink or purple flowers. Willowherb plants usually grow in disturbed areas such as roadsides and fields, and they can often be seen thriving in the aftermath of wildfires or other natural disturbances. The leaves are generally lance-shaped and arranged in opposite pairs along the stem. Some species of willowherb are used in traditional medicine and herbal remedies, while others are considered invasive due to their rapid growth and ability to spread quickly. The plant is also known for its role in supporting pollinators, as its flowers attract bees and other insects.
