A hipster that is equally earthy and hipster. They wear flannels, listen to Woody Guthrie, and plant things. This can be a person connected to the upper eschelon of "hipster" that just likes gardening and changing the world through love of mother earth and folk music. Or it can be a displaced hipster living in a rural setting. In short, they still ride fixies, but they live on (or plant) farms.
