"Oenothera biennis," Wikipedia, the free encyclopedia. Oenothera biennis (common evening-primrose,evening star, sun drop, weedy evening primrose, German rampion, hog weed, King's cure-all, or fever-plant.) is a species of Oenothera native to eastern and central North America, from Newfoundland west to Alberta, southeast to Florida, and southwest to Texas, and widely naturalized elsewhere in temperate and subtropical regions.Oenothera biennis has a life span of two years (biennial) growing to 30150 cm (1259 in) tall. The leaves are lanceolate, 520 cm (28 in) long and 12.5 cm (1⁄21 in) broad, produced in a tight rosette the first year, and spirally on a stem the second year. Blooming lasts from late spring to late summer. The flowers are hermaphrodite, produced on a tall spike and only last until the following noon. They open visibly fast every evening producing an interesting spectacle, hence the name "evening primrose." The blooms are yellow, 2.55 cm (12 in) diameter, with four bilobed petals. The flower structure has an invisible to the naked eye bright nectar guide pattern. This pattern is apparent under ultraviolet light and visible to its pollinators, moths, butterflies, and bees. The fruit is a capsule 24 cm (3⁄41 1⁄2 in) long and 46 mm (0.160.24 in) broad, containing numerous 12 mm (0.040.08 in) long seeds, released when the capsule splits into four sections at maturity. The seeds of the plant are important food for birds.
