This outside the Agastache and Salvia range, but get yourself some Coral Honeysuckle Lonicera sempervirons. Some types like Alabama Crimson and Major Wheeler will bloom on and off from spring into late fall. As to other salvias you can grow that depends on your soil type, drainage, and plant zone. You can do a lot if you are zone 7a or warmer and have soil that drains well in winter. Otherwise you are forced to either grow them as annuals or winter over plants indoors. The latter is a lot of fun but not for everyone and how to do that is another discussion.
