Japanese lady fern (sometimes also called black lady fern) is a deciduous fern which typically grows to 18\ tall (occasionally to 24\") and as wide. Features attractive blackish-green, upright arching, triangular fronds. Sori are arranged in a herringbone pattern on the undersides of the pinnae. Fiddleheads begin to unfurl in late spring after most other ferns are already leafed out. Spreads slowly by creeping rhizomes. Synonymous with and sometimes sold as Athyrium japonicum or Lunathyrium japonicum."
