Longevity of Perennials

When selecting perennials for the home landscape, it's important to consider their size, bloom period, hardiness, and cultural requirements. Another consideration is their longevity. Some perennials are extremely long-lived. For example, it's not uncommon to see 50- to 60-year-old peonies in older neighborhoods in Iowa. In contrast, some perennials tend to be short-lived. These short-lived perennials persist for several years and then decline and fade away.
