Some plants return year after year without needing to be replanted. A perennial plant lives for more than two growing seasons, often far longer. Herbaceous perennials die back to the ground in winter and regrow from the roots; woody perennials such as shrubs keep their stems above ground.

Gardeners value perennials for the reliable structure and seasonal color they provide. Hostas, peonies, daylilies, and many ornamental grasses settle in and improve with age. Once established they need less frequent watering and feeding than annuals, though division every few years keeps clumps vigorous.

Not every perennial is fully hardy in every climate. Check local hardiness ratings before planting. A well-chosen mix of early, mid, and late-season bloomers creates continuous interest from spring through autumn. Mulching and occasional feeding help them perform at their best.
