About Oenothera silesiaca
Oenothera silesiaca, known as Silesian Evening Primrose, is a biennial or short-lived perennial herbaceous plant, prized for its large, showy yellow flowers that open at dusk. Its upright stems and green foliage make it ideal for garden borders, flower beds, or as part of a wild garden, adding a touch of color and attracting nocturnal pollinators. Its blooming is spectacular during summer, creating a vibrant contrast in the night landscape.
Native range
Silesia (historical region of Central Europe)
Care tips
It prefers full sun exposure for abundant flowering and well-drained, sandy or loamy soil, even poor. Watering should be moderate, allowing the substrate to dry out between waterings, as it is quite drought tolerant once established. Avoid excessive soil moisture, which can lead to root rot. It self-seeds easily, so it may be necessary to control its spread if you don't want it to colonize other areas.
