watering

Water white evening primrose (Oenothera speciosa 'Rosea') deeply once per week, allowing the top 1–2 inches (2.5–5 cm) of soil to dry out before watering again. Do not water excessively as this will cause root rot. Water in the evening to reduce the risk of fungal diseases from water droplets lingering on the leaves.

sunlight

White evening primrose, Oenothera speciosa 'Rosea', needs at least 4-6 hours of direct sunlight daily. This plant should receive afternoon sun or dappled light in the morning. It will thrive in a well-drained soil in warmer climates, but can tolerate some shade as well.

pruning

Prune white evening primrose (Oenothera speciosa 'Rosea') early in spring before the new growth emerges.

Additionally, the plant should be cut back close to the ground to encourage better blooming and bushier growth.
