Asplenium scolopendrium

Hart's tongue fern

  • Botanical name: Asplenium scolopendrium
  • Common name: Hart's tongue fern
  • Family: Aspleniaceae
  • Plant Type: Perennial, Evergreen
Foliage colour:


The evergreen hart’s tongue fern, Asplenium scolopendrium, grows wild in shaded areas, often forming large drifts beneath trees among rocks and streams where its upright pointed ‘tongues’ contrast strikingly with the softer shapes of damp-loving wild flowers. In gardens, the plants are good for shaded wild areas, and are also invaluable for year round interest among shrubs or other shade and moisture loving perennials.


Once planted, Asplenium scolopendrium grows slowly and needs little attention apart from annual mulching and tidying in spring. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
