'hardy-leaved' originates from the combination of 'hardy,' meaning 'robust or capable of enduring difficult conditions,' and 'leaved,' referring to the leaves of a plant.

The term 'hardy' comes from Old French 'hardi,' meaning 'bold or brave,' and 'leaved' is derived from the Old English 'lēaf,' meaning 'leaf.'

Initially, 'hardy' meant 'bold or brave,' but in this context, it evolved to mean 'resilient or tough,' especially in relation to plants.
