They have neither flowers nor seeds – just lots of greenery! In this greenhouse you will see mostly tropical and subtropical ferns, along with some other spore-producing plants. Imagine a vast, hot and humid land, where most plants are horsetails and giant club mosses, other mosses and ferns. There are no dinosaurs yet and flowering plants won’t appear for another 150 million years. Welcome to the Carboniferous period, some 360 to 300 million years ago. Adapting means diversifying All living things have to adapt to their environment in order to survive. Ferns have done this very successfully, and can now be found everywhere. They are especially abundant in the hot, humid climates of the tropics and subtropics. Ferns have also adapted to places without much water. Their strategy? Highly diversified forms and growth habits: herbaceous ferns, epiphytic ferns, climbing ferns, tree ferns, rupestral ferns, aquatic ferns and xerophytic ferns.

Most species found in Quebec are of this type. Epiphytic ferns Their rhizomes of the epiphytic ferns cling to tree branches and trunks reaching toward the sunlight in the canopy. They remain in the shade of tall trees, however, where the air is moister. It’s the best of both worlds! Climbing ferns More rarely, on forest edges or in some open areas, you may come across some ferns anchored in the soil but with constantly growing fronds that climb tree trunks and twine around branches. Some of these ferns can be terribly invasive. Tree ferns A “trunk” raises these ferns above herbaceous plants. They grow in the midst of clearings in the forest, to take advantage of all the available sunlight. Some species are taller than the surrounding vegetation, stretching toward the sun. Rupestral ferns These ferns are often small and grow on rock slabs, scree and steep cliffs, hidden in cracks or at the base of crevices. The scales on their rhizomes protect them from drying out and their thicker fronds, covered in scales or hairs, help retain moisture. Aquatic ferns Some ferns grow directly in water, usually in calm, shallow spots. Their roots may be firmly anchored to the bottom or float freely on the surface. This gives them ready access to sunlight. Xerophytic ferns In places without much water, ferns have smaller, thicker fronds, often covered in hairs or a waxy substance that helps prevent water loss. Their rhizomes are protected by scales and can stretch for long distances in search of water and nutrients. Did you know?Did you know?One life, two plants Ferns do not produce flowers, fruit or seeds. Instead, they make spores, which germinate and form not a new fern, but an intermediate, rather discreet entity called a gametophyte. This leaf-like object is so tiny that it can often be hard to spot. The male and female gametes fuse on the gametophyte in the presence of water, creating a new fern. Some spores can remain viable for a very long time. In 1989, a group of researchers from Cambridge University managed to germinate a spore from a herbarium specimen collected 50 years earlier.
