My Nature Domain Cleric fights with a magic boosted Salami for that "hippie" feeling.
Druids have wild shape which makes them them unique to other classes [...] plus most people I've met tend to play druids as drug dealers anyways,
They're pretty much hippies in a sense.
LOL!
There is an amusing SI DnD fic (1st or 2nd ed ruleset) on Space Battles where one of the characters is a Necromancer and ex-Druid. He resigned from druidism when it dawned on him that most of his collegues were using shapeshifting for their furry-lusting perversions ...
That character retained his love for nature and keeps potted plants in his office. He also dresses in bright colours - none of that cheap black doom and gloom (you hear that, Shadowheart?) of all those other necromancers for him!
That was written quite a few years ago :P
