A flowerless vascular plant that reproduces by spores and typically has large, divided leaves called fronds that unfurl from coiled fiddleheads. Ferns are found worldwide and range from tiny aquatic species to tree-sized tropical forms.
From Old English 'fearn', related to Sanskrit 'parna' meaning leaf or feather, reflecting the feathery appearance of many fern fronds. The word has remained relatively unchanged across Germanic languages for over a thousand years.
Ferns are nature's ultimate time travelers, with some species virtually unchanged for 180 million years! Their iconic fiddlehead unfurling is actually a space-saving strategy that protects the delicate growing tip while the frond develops.
