A perennial is defined as a plant that will live for at least two years. Unlike shorter-lived annuals that must be replanted each year, perennials die at the end of the season and re-grow from the same roots the following year.
There are numerous varietals of perennial. Some common examples include begonia, aster, geranium and peony. Rose bushes, evergreens and bulbs, such as tulips and daffodils, are also perennials, as are many fruits and vegetables, for example, raspberries, onions and rhubarb.Learn more about Outdoor Plants & Flowers
