About Evening primrose
Oenothera suffrutescens, commonly known as scarlet gaura or scarlet evening primrose, is a herbaceous perennial that produces spikes of vibrant scarlet-pink flowers. Its delicate, butterfly-like blooms open sequentially along the stem, creating a lively display from spring through autumn. It is ideal for garden borders, rock gardens, or as part of a pollinator garden, adding a wild yet elegant touch.
Native range

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