I picked just 2 colors, hope that is OK. Green and Purple.
I have a Mexican Sage plant in the back yard that was there when we moved in, that I have a love-hate relationship with. I love it in other people's yards, but not my own. It's just a "space filler", I have to cut it back all the time and I really dislike the way the leaves smell. But it thrives on neglect, blooms most of the time and attracts hummingbirds and butterflies, so I guess it's staying.
