Evening Primrose (Oenothera)

Evening Primrose

Also known as: Suncups

The evening Primrose (Oenothera) are a group of herbaceous flowering plants. These plants are so-called because many of them bloom at dusk and stay open overnight – because of this trait, they are an important source of food for nighttime pollinators, such as moths and bats. Many evening Primrose are planted ornamentally. They are especially popular in the American southwest, where they are prized for their showy flowers and their high tolerance to drought.

Water: Originating from arid regions, evening Primrose is drought-tolerant and prefers minimal watering, ideally once a week for optimal health. As an outdoor plant in temperate zones, it requires less irrigation during dormancy, adapting to seasonal rainfall patterns.

Propagation: Evening Primrose can be propagated by seeds, cuttings, or division, with full sun, well-draining soil, and mild temperatures being essential. Seed sowing in spring is preferred, requiring light for germination. High humidity aids cuttings/divisions, while germination may vary. Steps include scattering seeds, lightly pressing, watering, and maintaining moisture.
