Western Sword Fern, Sword Fern, Giant Holly Fern, Aspidium munitum


Majestic and weather-resistant, award-winning Polystichum munitum (Western Sword Fern) is a robust evergreen fern forming a shapely, arching mound of long, narrowly lance-shaped, lustrous, dark green fronds.

They remain lush and fresh-looking throughout the season. Easily grown and versatile, Western Sword Fern is particularly beautiful as a specimen and most impressive planted in drifts in a woodland garden. Long-lasting when cut for arrangements.
