Oenothera biennis - evening primrose by Peggy Dawe

Oenothera biennis, or Evening Primrose, is a biennial plant native to North America, prized for its bright yellow flowers that bloom in the evening. Traditionally, the seeds of the plant have been used in herbal medicine, particularly for their rich content of gamma-linolenic acid (GLA), an essential fatty acid known for its anti-inflammatory properties. Evening Primrose oil is commonly used to support skin health, alleviate symptoms of eczema, and reduce inflammation in conditions such as rheumatoid arthritis. In folklore, Evening Primrose is often associated with love and romance. In some Native American traditions, the plant is considered a symbol of hope and healing, believed to help with both physical and emotional wounds.
