Sword Fern

Polystichum munitum · aka western sword fern

Sword fern produces long, upright fronds of neatly ranked, deep-green leaflets on sturdy stems. Wild-harvested in the Pacific Northwest, it is a reliable, inexpensive cut green with a fresh, natural character. Florists use its bold, tapering blades to build structure, add length and frame bouquets and arrangements. Hardier than many ferns, it holds its colour and form well through a design's life.
