The word "Onoclea Sensibilis" has its etymology rooted in Latin and Greek.
The genus name "Onoclea" is derived from the Latin word "onocle" or "onoclea", which refers to a type of fern. This Latin term originated from the Greek word "onos", meaning "donkey", and "kleio", meaning "to shut". The name "Onoclea" likely comes from the appearance of the fertile fronds of this fern, which resemble shut donkey’s ears.
The species name "Sensibilis" comes from the Latin word "sensibilis", meaning "sensitive". This name was given to the fern due to its sensitivity to frost. The fronds of the Onoclea Sensibilis are vulnerable to damage from below-freezing temperatures, causing them to wither and die.
