About Evening primrose
Oenothera editicaulis, known in Germany as Hochwüchsige Nachtkerze, is an imposing perennial plant that dazzles with its large, often fragrant, yellow flowers that open at dusk. Its upright and showy habit makes it ideal for the back of borders, cottage gardens, or as a focal point in mixed beds, adding a wild yet elegant touch. It is a robust plant that can reach considerable heights, creating a remarkable visual impact in the garden.
Native range
North America, specifically the central and eastern United States and southeastern Canada.
Care tips
It prefers full sun exposure for abundant flowering, although it tolerates some partial shade. It requires well-drained, sandy or loamy soil, and is quite drought-tolerant once established, so watering should be moderate. A common mistake is overwatering, which can lead to root rot; it's best to let the substrate dry out between waterings. It doesn't need much fertilization and can become invasive in some conditions, so consider its spread.
