Tree ferns are large, woody plants that belong to the group of ferns known as Pteridophytes. They typically have a tall, trunk-like stem and large, feathery leaves called fronds. These plants thrive in tropical and subtropical regions, often found in moist, shaded environments like rainforests. Tree ferns reproduce through spores rather than seeds, which are produced on the undersides of their fronds. They play a vital role in their ecosystems by providing habitat and food for various species. Some common types of tree ferns include Cyathea and Dicksonia, which are popular in gardens and landscaping.
