horsetails

Equisetum

Horsetails are unique plants that look like green, spiky tubes. They grow in wet areas and have been around for millions of years, making them one of the oldest plants on Earth!

Habitat: Wetlands

Appearance

The horsetails has unique jointed, hollow stems that are typically green or brownish. Instead of leaves, it has small, scale-like structures in whorls at each joint. Some species have feathery branches or a cone-like spore structure at the tip, making them look very distinct from flowering plants.

Interesting facts

"Living fossils," horsetails grew tall as trees when dinosaurs roamed the Earth!

People once used dried horsetail stems to scrub pots and pans like a natural sponge!

Some horsetail species can grow over 8 feet tall, making them giants among plants!

Their stems feel like sandpaper because they contain tiny glass-like crystals called silica!

Special abilities

Horsetails have tiny silica crystals in their stems, making them rough to touch. This helps them stand tall and deters many plant-eating animals.

Horsetails can grow roots (rhizomes) several meters deep, allowing them to find water far underground that other plants can't reach.

Horsetails have survived for over 300 million years, thanks to tough rhizomes that help them regrow even after harsh environmental changes.
