Life span for perennials

Asked March 9, 2016, 3:07 PM EST

I am trying to find a source that will give me an average life span for perennials. I am not looking for an exact number of years it will live but some indication of how long, if properly maintained, should different perennials live in my Montgomery County garden. I have searched but am not able to find such a resource. Thank you Terrie

Here's a longevity list that seems correct in our experience also for central Maryland:

You can also try searching "short-lived" or "long-lived" perennials to find more lists.
