Description

Western Sword Fern (Polystichum munitum) is a hardy evergreen fern native to western North America, including California. Its long, leathery, dark green fronds grow upright before arching gracefully outward, forming a lush, fountain-like clump. The finely divided, sword-shaped foliage adds rich texture and year-round greenery to shaded landscapes. Naturally found in woodland environments, this durable fern thrives in well-drained, humus-rich soil with partial to full shade. Ideal for woodland gardens, shaded borders, and naturalistic plantings, it brings a timeless forest character to the landscape.
