Water: Fragrant evening-primrose thrives in moderate moisture environments with a preference for deep, infrequent watering, ideally once a week. It balances drought resistance with periodic moisture needs, making it suitable for xeriscaping and reflecting its natural water conservation habits.

Fertilize: Fertilize fragrant evening-primrose with balanced nutrition every 4-6 weeks during growth, using high-nitrogen options for foliage. Adjust feeding seasonally, and avoid root burn by proper dilution. Use slow-release or water-soluble fertilizers, monitoring the plant's response to ensure consistent care and vibrant results.

Pruning: Fragrant evening-primrose is a herbaceous perennial with yellow blooms and a sweet fragrance. Prune in early to late spring to remove dead stems and spent flowers, promoting healthy growth and extended blooming. Use sanitized tools to prevent disease and support robust flowering while avoiding heavy pruning to maintain shape.

Propagation: Fragrant evening-primrose is best propagated by sowing in well-draining soil, either directly in beds or indoors in trays. For optimal germination, maintain a warm environment. Careful transplanting of developed seedlings and consistent watering while preventing waterlogging are essential for healthy growth.
