Surely a practice worth borrowing or reviving? Leigh Fermor describes a woman beginning each verse of her song with such an invocation, a kind of homage to the leaves and the trees.
‘She sang a doina to herself as she moved about the yard, each verse beginning “Foaie verde!” – “Green leaf” – or “Frunze verde!” – ” Green frond”. These green-leaf invocations always struck me as a sort of woodland salute to beech, ash, oak, pine and thorn, as if the trees and their foliage held some mysterious and beneficent power.’
