Meaning

noun any of various tropical American deciduous shrubs or trees of the genus Plumeria having milky sap and showy fragrant funnel-shaped variously colored flowers

originFrom French frangipane, from Italian frangipane. Possibly named after Muzio Frangipane, a 16th-century marquess of the Italian noble Frangipani family, who invented a plumeria-scented perfume. The name Frangipane derives from frangere (“to break”) + pane (“bread”), a reference to the family's distribution of bread in time of famine.
