Notes
Western oakfern (Gymnocarpium dryopteris) is a fern for ground cover and woodland gardens. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full sun to full shade and moist soil. It grows 6 to 16 inches tall and forms a colony. The triangular fronds are delicate and deeply cut into threes. It spreads quickly and is easy to establish, and it dies down in fall.
Pairs well with Humpback Whale hosta, Pacific bleeding heart, and Canada wild rye.
