Carex davalliana, commonly known as Davall’s sedge, is a perennial herbaceous plant native to calcareous fens and wet meadows throughout continental Europe. This dioecious species, with separate male and female plants, is adapted to wet, marshy habitats, specifically those with alkaline, nutrient-poor soils. It forms dense tussocks and features long, narrow, arching leaves that give it a grass-like appearance. Davall’s sedge is not commonly cultivated but can be used in naturalistic plantings and for habitat restoration in appropriate wetland settings.

Davall’s sedge is valued for its ecological role in wetland environments, providing habitat for various wildlife species. It is not typically used in conventional gardening but may be of interest for conservation projects or in creating wetland gardens. In cultivation, it requires consistently moist to wet conditions and can tolerate partial shade. While not known for showy flowers, its foliage and form can add texture to plantings. Carex davalliana is not prone to serious pests or diseases but can be sensitive to drought and waterlogged conditions. It is not considered invasive and does not have aggressive roots.CC BY-SA 4.0
