What are some good, long-lived 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 short-lived. Short-lived perennials persist for several years and then decline and fade away. In contrast, some perennials are extremely long-lived. It’s not uncommon to see 50- to 60-year-old peonies in the yards of older homes in Iowa.
Long-lived perennials include black snakeroot (Actaea racemosa), lady’s mantle (Alchemilla mollis), goatsbeard (Aruncus dioicus), butterfly weed (Asclepias tuberosa), false blue indigo (Baptisia australis), gas plant (Dictamnus albus), ferns (various species), hardy geranium (Geranium spp.), ornamental grasses (various species), daylily (Hemerocallis spp.), hosta (Hosta spp.), Siberian iris (Iris sibirica), blazing star (Liatris spp.), daffodil (Narcissus spp.), peony (Paeonia spp.), balloon flower (Platycodon grandiflorus), lungwort (Pulmonaria spp.), black-eyed susan (Rudbeckia fulgida ‘Goldsturm’), stonecrop (Sedum spp.), and Carolina lupine (Thermopsis villosa).
When given favorable growing conditions and good care, long-lived perennials often thrive for 20 or more years.
