About Evening primrose
Oenothera wratislaviensis, known as 'polskt nattljus' or Wratislaw's evening primrose, is an attractive perennial from the Onagraceae family, prized for its large, fragrant lemon-yellow flowers that open at dusk. Its robust reddish stems and dark green foliage create a striking contrast, adding a vibrant touch to cottage gardens, mixed borders, or flower beds where its nocturnal bloom can be admired. It's an excellent choice for attracting nocturnal pollinators and adding visual interest to the garden at the end of the day.

Care tips
This evening primrose thrives in full sun for abundant flowering, though it can tolerate some partial shade. It requires well-drained soil, preferably sandy or with good gravel content, and is quite drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out between waterings. A common mistake is overwatering, which can lead to root rot; ensure excellent drainage for its health. It can benefit from deadheading spent flowers to encourage continuous blooming and prevent excessive self-seeding, if not desired.
