Native to: California to Alaska and Montana, Idaho, and South Dakota.
Most common fern of Western forests. To 2–4 ft. high and wide. Leathery, lustrous dark green fronds are erect, then spreading. Each leaflet is dagger shaped, with toothed edges and a base that looks rather like a sword hilt. Old plants may have 75–100 fronds. Long lasting when cut for arrangements. Established plants get by with reduced moisture.
