16 interesting facts about ferns

Of all the plant families on earth, ferns are among the most ancient. Their ancestors found even dinosaurs roaming our planet millions of years ago, and since then the ferns themselves have changed rather little. Their most gigantic varieties either died out or were crushed over time, but those that grow today, from the point of view of botany, hardly differ from their distant predecessors. And due to the lack of flowers open to the eyes, they caused riddles in people for many centuries, until scientists finally revealed their secret.

Interesting facts about ferns

  10. Ferns secrete special substances that inhibit the vital activity of other organisms, including plants.
  11. Despite the foregoing, some of their species are used as medicinal plants.
  12. The trunks of tree ferns serve as building material in the tropics, and in Hawaii, their starchy core is used as food.
  13. The black tree fern growing in New Zealand reaches more than 20 meters in height and has a girth of about 50 centimeters (interesting facts about New Zealand).
  14. Some species of ferns are very poisonous.
  15. Japanese researchers have found that ferns remove radiation from the body.
