An iris plant (Iris foetidissima) native to Europe, also called the stinking iris or roast beef plant.
From Middle English or Old English origins, possibly combining 'glad' (bright, as the flower is) and 'wine' or 'wynn' (an Old English name element). The exact etymology is disputed.
Gladwin irises smell like rotting meat to attract carrion flies as pollinators—nature's gross-out strategy that actually works, showing sometimes stinkiness is a feature, not a bug!
