About White evening primrose
Oenothera acaulis, commonly known as Don Diego de la Noche or Stemless Evening Primrose, is a low-growing perennial admired for its large white flowers that unfurl at dusk and close at dawn, often turning pink before wilting. Its blooms and creeping foliage make it ideal for rock gardens, path edges, or as ground cover in low-maintenance landscapes, providing an ephemeral touch of nocturnal beauty.
Native range

Care tips
It thrives in full sun exposure and well-drained, sandy, or slightly poor soil. This plant is drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out between waterings to prevent waterlogging. Avoid heavy, clayey soils, as they can lead to root rot. A common mistake is overwatering, which can be detrimental to its health.
