About Evening primrose
Oenothera moravica, known as Moravian evening primrose, is a biennial herbaceous plant distinguished by its striking yellow flowers that unfurl at dusk. It is perfect for cottage gardens, roadside borders, or flowerbeds where its vibrant petals can illuminate the night landscape.

Care tips
It thrives in full sun for abundant flowering, though it can tolerate some partial shade. Moderate watering is required, allowing the substrate to dry out slightly between waterings, and it is drought-tolerant once established. It adapts to a wide range of soils, as long as they are well-drained, including poor or sandy ones. A common mistake is overwatering, which can lead to root rot, so ensure the soil does not become waterlogged.
