Festuca glauca

Blue fescue

  • Botanical name: Festuca glauca
  • Common name: Blue fescue
  • Family: Poaceae
  • Plant Type: Perennial
Foliage colour:


The truest blue of the dwarf grasses and totally drought-proof once established, Festuca glauca has stiff thread-like blue foliage which forms dense, upright tussocks, from which steel blue flower-heads appear in summer. It’s perfect for growing in a rock garden, where it teams well with a wide variety of rock plants. It’s also suitable for using in container displays.


For best results and to develop the most intense foliage colour, grow Festuca glauca in well-drained soil in full sun. Remove dead foliage in winter.
