Miten monivuotinen kasvi määritellään?
A perennial plant or simply perennial is a plant that lives more than two years. The term ("per-" + "-ennial", "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.
