“Melliferous” means “producing honey,” but it doesn’t apply just to bees and their hives. The adjective also applies to the plants that produce the substances collected by bees. It comes from the Latin “mellifer” (“honey bearing”), with “mel” meaning “sweet” and “fer” meaning “bearing.” The word is similar to the better-known adjective “mellifluous,” which means “sweet or musical; pleasant to hear” and is sometimes used to describe voices and sounds.
