Unlike an annual, a perennial plant is one with a life cycle that spans at least two years and blooms repeatedly throughout multiple seasons. A garden that primarily uses perennials will require less replanting and maintenance than one stocked with annuals. But while annual blooms stick around for months, a perennial flowering period is much shorter.
Many of these plants possess botanical features that help them weather cold or dry seasons. Common annuals include black-eyed susans, ferns, orchids, and daffodils (pictured).
