Overview
Ferns are a group of vascular, spore-producing plants that are distinct from both flowering plants and conifers. They are characterized by their lush foliage and unique reproductive structures, in which spores develop in special structures called sori on the undersides of the fronds. Ferns are an important part of many terrestrial ecosystems, providing oxygen and food for wildlife, as well as providing habitat for other plants. In addition, ferns are important to humans; they are used in farming, landscaping, and many traditional medicinal practices.
