Woodwardia fimbriata (Giant Chain Fern)

Giant Chain Fern, Giant Chainfern, Woodwardia chamissoi


Popular in California gardens, award-winning Woodwardia fimbriata (Giant Chain Fern) is a large evergreen fern adorned with tall, arching, twice-divided fronds, up to 8 ft. long (240 cm). The lacy, lance-shaped, apple green fronds rise from dense cinnamon crowns of short, stout rhizomes. The short but broad sori are arranged in neat lines on the undersides of the fronds and are prominently visible on their upper surfaces. Native from British Columbia to Mexico, Giant Chain Fern is the largest fern in North America. This coastal species grows in moist coniferous woodlands and is particularly impressive in the redwood forests. Withstanding neglect once established, Giant Chain Fern can be used alongside a pond or stream, against a shaded wall, or in a woodland garden. Excellent as an accent in shaded areas.

  • Grows up to 4-8 ft. tall and wide (120-240 cm).
  • Performs well in part shade to full shade in neutral to acidic, moderately fertile soil with plentiful moisture. In frost prone areas shelter from cold, drying winds and protect in winter with a dry mulch.
  • Perfect for beds and borders, hedges, cottage gardens or containers.
  • Generally pest and disease free. Deer resistant.
  • Cut down old fronds when they deteriorate
  • Propagate by division or from spores.
  • Native to western North America from British Columbia through California, including the Sierra Nevada, into Baja California.
