Its most unique feature is the striking golden-yellow, powdery coating found on the underside of its fronds, which gives it its common name. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Polypodiopsida - **Order:** Polypodiales - **Family:** Pteridaceae - **Genus:** Pentagramma ## Interesting facts - Goldback ferns don't grow flowers or seeds; they reproduce using microscopic spores hidden beneath their fronds. - Its scientific name, Pentagramma, refers to the frond's five-sided, star-like base shape! - The golden powder isn't pollen or dust; it's a special wax that protects the fern! - These ferns are ancient, belonging to a plant group that lived with dinosaurs millions of years ago! ## Special abilities - **Golden Sunscreen:** Goldback fern can produce a powdery, golden-yellow wax on its fronds that helps protect it from sun and dehydration. - **Rock Hugger:** Goldback fern has tough rhizomes and roots that allow it to anchor securely in rock crevices, even on steep cliffs. - **Drought Dodger:** Goldback fern can curl its fronds tightly during dry periods, reducing water loss and reviving when moisture returns. ## Measurements & details - **Height:** 10-30 cm - **Spread:** 10-30 cm - **Edible:** No - **Toxicity:** None - **Lifecycle:** Perennial ## Ecological connections - **Eaten by:** California banana slug (*Ariolimax californicus*) — Grazes on the fern's fronds in its native habitat. - **Shelter:** [Common rough woodlouse](https://www.snappit.app/explore/common-rough-woodlouse) (*Porcellio scaber*) — Finds cool, damp refuge beneath the fern's fronds and rhizomes. - **Shelter:** Marsh wolf spider (*Pardosa amentata*) — Uses the fern's fronds and damp base as hunting grounds and refuge. ## Traits - [Ornamental](https://www.snappit.app/explore/traits/ornamental): Ornamental plants are cultivated primarily for their aesthetic appeal, enhancing landscapes and gardens with their attractive foliage, flowers, or form. - [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. - [Colorful](https://www.snappit.app/explore/traits/colorful): Colorful describes organisms or objects displaying a wide range of bright and distinct colors. - [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. ## Collections - [Plants](https://www.snappit.app/explore/collections/plants) ## Safety **Danger:** 1/5 · Very low Always look but don't touch wild plants unless you have an adult with you. ## Frequently Asked Questions ### How to identify goldback fern?
