Water can easily flow through its hollow stems, helping it survive in damp places.

Special abilities

Rough horsetail has a special coating of silica in its stems that makes it tough and helps defend against hungry nibblers.

This plant has deep underground stems called rhizomes that help it spread widely and survive harsh conditions.

Instead of seeds, rough horsetail releases tiny spores that float on the wind to grow new plants far away.
