flourishing adj. palmy

My car is a 2001 Saturn wagon, L-series, bought new. Saturn was “a different kind of car company” …  When you bought a Saturn, back in those palmy days, the dealer took a picture of you posing next to your new vehicle, wearing a Saturn hat, and perhaps a Saturn T-shirt. You were part of the Saturn family. (Jean Thompson, “All Things Come to an End,” The New York Times, 3/19/2016.)

This word can be synonymous with prosperous, successful, thriving or booming, when used in the sense of flourishing.
