The process or period of putting forth fronds or leaves; the season when trees and plants develop their leafy growth.
From Latin 'frondescentia', derived from 'frondescere' (to put forth leaves) + '-ence' suffix (forming abstract nouns). Developed as a botanical term in the 17th-18th centuries.
Just like 'efflorescence' describes flowering and 'arborescence' describes tree-like growth, 'frondescence' is a poetic scientific term for that magical spring moment when plants suddenly burst into leaf.
