Perennial plants give you a large selection of colour options and you can look forward to their return every year
Perennials are non-woody plants that live longer than two years. They generally bloom once a year, for anywhere from a day to more than a month. Most perennials die back to their roots in the fall, although some varieties will remain green through out the winter. Some perennials, like hollyhock and delphinium have a short lifespan, and may live for only four or five years. Other perennial plants, such as, aster and peony, can last for decades with little attention. Perennial plants give you a large selection of colour options and you can look forward to their return every year. They are also considerably easier to move than most shrubs. Do not expect your perennial plants to flower the first year that they are planted. It will usually take the plant a full season to become well established and it will flower the second year.
