Asparagus has a distinctive butterscotch color in winter. This big asparagus plant (Asparagus officinalis) is along a roadside in Benton County. Some roadsides in western Benton County and Warren County have substantial populations of asparagus growing wild. Take highway US 52 west of Lafayette and you can find asparagus on the roadside where you encounter the first wind turbine.
