Long-Lived Perennials

If you want flowers your future grandchildren can enjoy, try planting peonies—under the right conditions, they have been known to survive for 70 to 100 years

These low-maintenance, shade garden favorites can live well beyond 15 years. 

Don't be fooled by the name—though a single bloom only lasts for a day, daylilies live for 3 to 6 years, and can go on even longer if you divide the plants once they start to fizzle out.

Perennial winter color may seem like a dream come true, but hellebore, also called lenton roses, provide late-winter and early spring color year after year.
