Sword Fern

CAN BE FOUND IN:

Sword Fern

Polystichum munitum

Appearance

The sword fern has dark, evergreen fronds (leaves) that can be as tall as 1.5 metres. The fronds grow from the plant in a clump. They have large, toothed leaves. 

range & Habitat

The sword fern grows from Alaska to south California in coastal or moist areas. It is often found growing with western red cedar in damp forests with lots of shade.

reciprocal relationships

Sword ferns reproduce by spores, not by seeds; they need lots of moisture to spread the spores to sprout in a new spot. The new fronds start as curled stems, called “fiddleheads”. 

The fronds create branching out areas that create habitat and cover for ground-nesting birds and small rodents. Every part of the sword fern can be used for cooking and eating. The roots (rhizomes) are used for cooking and eaten with salmon eggs. The leaves (fronds) of the plant are used to line cooking pits and baskets, beds and floors. The Nuu-chah-nulth people use the fern to treat symptoms of diarrhea, the Quinalts peoples use it to treat dandruff, and Lummi women would chew on the plant to help with childbirth. 

Some coastal peoples such as the Squamish and Ditidaht used the fern to play a game called “Pala Pala”. This game was played by pulling off the leaflets of the fern one by one while saying “Pala” meaning “One” while holding their breath. This game could be played by children, but was also used as a training tool for young men so they could dive down in the ocean to harvest bull kelp.
