Noun A perennial plant. Herbaceous perennials survive winter and drought as underground roots, rhizomes, bulbs, corms, or tubers. Woody perennials, including vines, shrubs, and trees, usually stop growing during winter and drought. Asters, irises, tulips, and peonies are familiar garden perennials. Compare annual, biennial.
