A fern is a type of plant that belongs to the group known as pteridophytes. Unlike flowering plants, ferns reproduce through spores instead of seeds. They typically have feathery, green leaves called fronds, which can vary in size and shape. Ferns thrive in moist, shaded environments, making them common in forests and gardens. Ferns are ancient plants, with a history dating back over 300 million years. They play an important role in ecosystems by providing habitat and food for various organisms. Some popular types of ferns include Boston fern and staghorn fern, which are often used in home decor and landscaping.
