"Sugar from the Sun" is Garfield Park Conservatory's newest permanent exhibit. RikRock has combined both water features and steel sculpture work to complete the most cutting edge exhibit in the world on photosynthesis. 1,850 plants, 3,900 linear feet of steel and 200 tons of stone create this sense-dazzling exhibit, which opened in March 2008. Garfield Park Conservatory is located at 300 N. Central Park Ave in Chicago.
