Adiantum raddianum ‘Fritz-Lüthi’ is a cultivated Maidenhair Fern with broad leaflets edged by deep rounded curves. They overlap across triangular fronds, creating full green layers above the slender black stalks.
Each young frond begins as a tight curve just above the surface. As it uncurls, the triangular outline widens and the rounded leaf sections open into view. Branching below the surface adds further arches around the base and gradually joins them into a dense clump.
