The foliage or leafy covering of trees and plants; the collective leaves and leafy branches of vegetation.
From French 'frondaison' or Latin 'fronda' (frond, referring to leafy branches), + English suffix '-age' (meaning collection or aggregate). Developed in the 16th-17th centuries as a technical botanical term.
While 'frondage' is a lovely word for the green leafy canopy of a forest, it's mostly fallen out of use in favor of simpler words like 'foliage'—but it shows up in poetry for its elegant sound.
