About Evening primrose
Oenothera paradoxa, commonly known as Wiesiołek dziwny, is a biennial or short-lived perennial evening primrose species, cherished for its large, fragrant yellow flowers that open at dusk and last until morning. Its upright stems and lance-shaped leaves form attractive foliage, and its abundant bloom creates a vibrant display in cottage gardens, sunny borders, or flower beds. It is particularly well-suited for moon gardens, where its blossoms illuminate in the moonlight.
Native range
Central and Eastern Europe
Care tips
This evening primrose thrives in full sun for optimal flowering and prefers well-drained soil, even poor or sandy, as it does not tolerate waterlogging. Watering should be moderate, allowing the soil to dry out between waterings, and it's important to avoid excessive moisture, especially in winter, to prevent root rot. A common mistake is planting it in heavy or overly fertile soils, which can lead to excessive foliage growth at the expense of flowering and reduced disease resistance.
How to save a dying Evening primrose
- Warning signs
- Yellowish or reddish leaves, weak and limp stems, lack of flowering or prematurely wilted flowers.
- First aid
- Check drainage. If waterlogged, repot to dry, aerated soil. If very dry, water deeply.
- What kills it
- Excessive moisture and poor drainage are its worst enemies, causing root rot.
- Can it be saved?
- Yes, if rot is not too advanced and watering/drainage are corrected promptly.
