climbing fern

The term "climbing fern" refers to several fern species within the genus Lygodium. A notable example is Lygodium palmatum, a delicate North American fern characterized by a twining stem and palmately lobed sterile fronds. These ferns are also known as creeping ferns.1

Climbing ferns, such as Lygodium japonicum and L. microphyllum, have been introduced to tropical or subtropical areas like southern Florida and Hawaii, where they have naturalized and spread into native forests.2

Ferns, in general, are most abundant in tropical regions and are typically found in shaded, damp forests. Some species can grow on soil or rocks, while others are adapted to dry habitats with features like thick cuticles and abundant hairs. While most ferns prefer shade, some, like Gleichenia, are adapted to open, sunny sites.3
