This is an easy place to miss, so you need to slow down and really look for it. In an old yellow house tucked way back on a long gravel driveway between the Taco Bell and Goody Goody Liquor, Sunshine Trees is a longtime survivor from the semi-rural hippie days of Upper Greenville. Founded in 1965, Sunshine's main specialty is bonsai — the tiny Japanese miniatures grown in bowls — but they also carry a line of exotic citrus, miniature lime, orange and lemon, that can survive well, if properly tended, on apartment balconies in Texas. Some of the plants at Sunshine are imported from Central America and Asia, but more are grown from seed in a 7,400-foot greenhouse that is open to the public. Even if you're not in the market for a tree, this is a cool place to visit on a slow weekend.
