# rough horsetail (*Equisetum hyemale*) Rough horsetail is a tall, green plant that looks like a bunch of thin tubes. It grows in wet places and is very old, dating back millions of years! - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 12 - **Habitat:** Wetlands ![rough horsetail](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Equiseto_de_invierno_%28Equisetum_hyemale%29%252C_jard%C3%ADn_bot%C3%A1nico_alpino-%C3%A1rtico%252C_Troms%C3%B8%252C_Noruega%252C_2019-09-04%252C_DD_81.jpg&width=800) Photo: Diego Delso, CC BY-SA 4.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Equiseto_de_invierno_%28Equisetum_hyemale%29%252C_jard%C3%ADn_bot%C3%A1nico_alpino-%C3%A1rtico%252C_Troms%C3%B8%252C_Noruega%252C_2019-09-04%252C_DD_81.jpg) ## Appearance The rough horsetail has rigid, dark green, hollow stems with distinct black bands at each joint. Its unique segmented appearance and rough, sandpaper-like texture make it easily identifiable, lacking true leaves or showy flowers. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Polypodiopsida - **Order:** Equisetales - **Family:** Equisetaceae - **Genus:** Equisetum ## Interesting facts - Its stems feel like sandpaper because they are packed with tiny glass-like crystals! - People once used these plants like scrubbing brushes to clean pots and pans! - Rough horsetail is an ancient plant, alive when dinosaurs roamed the Earth! - Water can easily flow through its hollow stems, helping it survive in damp places. ## Special abilities - **Nature's Scrubber:** Rough horsetail has a special coating of silica in its stems that makes it tough and helps defend against hungry nibblers. - **Underground Explorer:** This plant has deep underground stems called rhizomes that help it spread widely and survive harsh conditions. - **Spore Sprinter:** Instead of seeds, rough horsetail releases tiny spores that float on the wind to grow new plants far away. ## Measurements & details - **Height:** 30-150 cm - **Spread:** 30-100 cm - **Edible:** No - **Toxicity:** Mild - **Lifecycle:** Perennial - **Pollination Method:** Wind ## Ecological connections - **Eaten by:** [White-tailed deer](https://www.snappit.app/explore/white-tailed-deer) (*Odocoileus virginianus*) — Browses stems, especially new shoots. - **Eaten by:** Horsetail aphid (*Hyalopteroides humilis*) — Feeds on sap from its stems. - **Parasitizes:** Horsetail rust (*Puccinia equiseti*) — Grows on its stems, causing rust-like spots. ## Traits - [Nonvascular](https://www.snappit.app/explore/traits/nonvascular): This trait characterizes plants lacking specialized vascular tissues (xylem and phloem) for transporting water and nutrients. - [Grass-Like](https://www.snappit.app/explore/traits/grass-like): Grass-like plants are herbaceous plants that visually resemble true grasses, typically having long, narrow leaves. - [Ancient Lineage](https://www.snappit.app/explore/traits/ancient-lineage): This trait signifies organisms belonging to a very old evolutionary group with ancestors dating back millions of years. - [Decomposer](https://www.snappit.app/explore/traits/decomposer): Describes organisms that break down dead organic material, recycling nutrients back into the ecosystem. - [Longevous](https://www.snappit.app/explore/traits/longevous): This trait characterizes organisms with an exceptionally long lifespan compared to others of their kind. - [Wetland](https://www.snappit.app/explore/traits/wetland): This habitat trait identifies species found in wetlands, which are areas of land saturated with water, either permanently or seasonally, including marshes, swamps, and bogs. ## 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 rough horsetail?
