Its dark green, leathery leaflets are distinctively sword-shaped, with tiny 'ears' at their base, giving it a rough, saw-toothed edge. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Polypodiopsida - **Order:** Polypodiales - **Family:** Dryopteridaceae - **Genus:** Polystichum ## Interesting facts - Indigenous peoples historically used its roots for food after roasting, like small potatoes! - Its fronds can grow up to two meters long, making it one of the largest ferns in its range! - Look closely for tiny bumps on the underside of old fronds; these are sori, where spores are made! - Some western sword ferns can live for over 100 years, a true forest elder! ## Special abilities - **Spore Power!:** Western sword fern can reproduce using tiny spores, invisible to the eye, spreading new ferns far and wide without seeds! - **Tough Leathery Shield:** Western sword fern has strong, leathery fronds that help it survive dry spells and protect against hungry critters. - **Winter Green Keeper:** This fern can keep its green fronds all winter, collecting sunlight even when other plants lose their leaves. ## Measurements & details - **Height:** 50-150 cm - **Spread:** 60-100 cm - **Edible:** Yes - **Toxicity:** None - **Lifecycle:** Perennial ## Ecological connections - **Eaten by:** [mule deer](https://www.snappit.app/explore/mule-deer) (*Odocoileus hemionus*) — Browses on fronds, especially in winter when other food is scarce. - **Shelter:** [northern red-legged frog](https://www.snappit.app/explore/northern-red-legged-frog) (*Rana aurora*) — Uses dense fronds for hiding from predators and staying moist. - **Shelter:** [deer mouse](https://www.snappit.app/explore/deer-mouse) (*Peromyscus maniculatus*) — Builds nests under its protective fronds. - **Depends on:** [Douglas fir](https://www.snappit.app/explore/douglas-fir) (*Pseudotsuga menziesii*) — Thrives in the shade of these towering trees. ## Traits - [Shade Tolerant](https://www.snappit.app/explore/traits/shade-tolerant): Shade tolerant plants are adapted to grow and thrive in areas with low light levels, requiring less direct sunlight. - [Evergreen](https://www.snappit.app/explore/traits/evergreen): Evergreen plants retain their foliage throughout the year, never shedding all their leaves at once. - [Spore Producing](https://www.snappit.app/explore/traits/spore-producing): Spore-producing organisms reproduce by releasing small, often single-celled, reproductive units called spores. - [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life. - [Longevous](https://www.snappit.app/explore/traits/longevous): This trait characterizes organisms with an exceptionally long lifespan compared to others of their kind. ## Collections - [Plants](https://www.snappit.app/explore/collections/plants) ## Safety **Danger:** 1/5 · Very low Don't touch plants unless you know they are safe, and always wash your hands after exploring. ## Frequently Asked Questions ### How to identify western sword fern?
