About Sea centaury

Centaurium maritimum, also known as Seaside Centaury, is a small annual herbaceous plant belonging to the Gentianaceae family, noted for its delicate pink or white flowers with a yellow center. It thrives in coastal and saline areas, making it ideal for rock gardens with maritime influences or for pots on balconies with sea views. Its compact size and abundant flowering make it a charming option to add a subtle touch of color in arid and sunny environments.

Care tips

This plant prefers full sun exposure for optimal flowering, tolerating partial shade in very hot climates. It requires moderate watering, allowing the substrate to dry out slightly between waterings, and is quite drought-tolerant once established. Use a sandy, well-draining substrate, ideally with some salinity, to replicate its natural habitat. Avoid overwatering and heavy soils, as it is prone to root rot in waterlogged conditions.
