About Redstem evening primrose
Oenothera rubricaulis, commonly known as Red-stemmed Evening Primrose, is a perennial or biennial herbaceous plant native to North America, cherished for its vibrant yellow flowers that unfurl at dusk. Its distinctive reddish stems add ornamental interest, creating an attractive contrast with the green foliage.

Care tips
It thrives in full sun for abundant flowering, although it tolerates some partial shade. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it is sensitive to waterlogging. It prospers in well-drained soils, preferably sandy or stony, and is quite drought-tolerant once established. A common mistake is overwatering, which can lead to root rot.
