Growing notes

  • Plant in dappled shade — provides year-round texture and structure where most perennials disappear in winter
  • Evergreen — cut out only the oldest fronds in spring as new growth begins
  • Native to British woodland — the standard shade-garden fern in cool maritime climates
  • Many forms exist — ‘Plumosum Densum’ has particularly fine soft fronds
