Oenothera fruticosa, commonly known as Narrowleaf Evening Primrose or Sundrops, is a deciduous perennial herb native to open woodlands, grasslands, and roadside areas in the Southeastern USA. It typically grows to a height of 16-36 inches (40-91 cm) and is appreciated for its bright yellow flowers. The plant forms a bushy clump with lance-shaped leaves and bears cup-shaped, lemon-yellow flowers that are about 1-2 inches (2.5-5 cm) across. These blooms are particularly showy and open in the evening, hence the common name. Flowering occurs from late spring to early summer.

Narrowleaf Evening Primrose is valued for its drought tolerance and its ability to attract pollinators such as bees and butterflies. It is often used in wildflower gardens, borders, and naturalized areas. This plant thrives in full sun but can tolerate light shade. It prefers acidic, well-drained sandy soils but is adaptable to various soil types, including those with varying pH levels. While it requires high amounts of water initially, once established, it is quite drought-resistant. Potential problems include root rot in overly wet soils and occasional issues with pests such as aphids.CC BY-SA 4.0
