perennial


perennial

Any plant that persists for several years, usually with new herbaceous growth from a part that survives from season to season. Trees and shrubs are perennial, as are some herbaceous flowers and vegetative ground covers. Perennials have only a limited flowering period, but, with maintenance throughout the growing season, they provide a leafy presence and shape to the garden landscape. Popular flowering perennials include bellflowers, chrysanthemums, columbines, larkspurs, hollyhocks, phlox, pinks, poppies, and primroses. See also annual, biennial.
