Western Sword Fern From the NW United States, Polystichum munitum is a very large, handsome, evergreen clump-forming fern, with a spreading ‘shuttlecock’ habit and narrow, leathery, dark-green fronds with bristly tips. It is very hardy, robust and reliable, tolerating poor soil and retaining its good looks even in hot, dry weather, and will even tolerate full sun if the soil is moist. The western sword fern is a striking structural plant with year-round presence in a shady border. Remove old fronds in late winter to keep the plant looking at its best. Holds the RHS Award of Garden Merit.
