Evening Primrose 100 Seeds Oenothera biennis

Oenothera biennis, commonly known as the evening primrose, is a biennial wildflower belonging to the family Onagraceae. Native to North America, it has spread widely across Europe, Asia, and other temperate regions, often thriving in disturbed soils, open meadows, and along roadsides. In its first year, the plant forms a basal rosette of lanceolate leaves that store energy in a thick taproot, and in the second year it produces an erect, branching stem that can reach up to 1.5 meters tall. The stem is covered with alternating leaves and bears numerous buds that open into bright yellow, four-petaled flowers. Each flower blooms in the evening—hence the common name—and emits a light, sweet fragrance that attracts night-flying pollinators, particularly hawk moths. The flowers close by the following morning, making the plant a symbol of fleeting beauty and nocturnal life. Flowering occurs from late spring through autumn, followed by the development of elongated seed capsules containing small brown seeds. Ecologically, Oenothera biennis provides nectar for pollinators and seeds for birds and small mammals. It is a hardy and adaptable species, preferring full sun and well-drained, sandy or gravelly soils, and it plays an important role in stabilizing disturbed habitats while adding subtle beauty to wild landscapes.
