Are salvias annual or perennial? Are agastache perennial?
I have grown both for the first time from plug plants. I need the space for winter flowers but am not sure if I should dig them up or leave them. Both have a large healthy root ball.

There are annual and perennial varieties of salvia so it depends on what variety you have.
Agastache is perennial in colder zones and most likely is perennial in your location. So I wouldn't pull it out.
