Care tips
This evening primrose prefers full sun for abundant flowering, although it tolerates some partial shade. It requires regular watering in its early stages, becoming more drought-tolerant once established, but avoid waterlogging. It thrives in well-drained, even poor soils, and the most common mistake is planting it in heavy or excessively wet soils, which can lead to root rot.
