Faits intéressants

Hop Flatsedge has slender, grass-like stems and leaves. Its small flower clusters develop into distinctive rounded, hop-like seed clusters, giving it its common name. It is a good choice for dry prairie gardens, native lawns, and naturalized areas. It tolerates drought once established. It prefers lean, well-drained soil. It forms small clumps and is usually well behaved. It does not require regular pruning or division. It can be a useful lower-growing plant beneath taller prairie flowers and grasses.
