This ongoing program runs from Wednesday, April 2, to Sunday, June 22. Hours are 10 a.m. to 4 p.m. Wednesdays to Sundays.Pollinators are an essential part of the natural world. One in three bites of food we eat depends on pollinators. From butterflies and bees to beetles and birds, many kinds of pollinators have evolved within their ecosystems by building unique relationships with plants. Smithsonian Gardens Pollination Investigation exhibit takes participants on an exploration of the who, what, when, where, why and how of pollination by interpreting the unique relationship between pollinators and flowers.Pollination Investigation was created by Smithsonian Gardens in collaboration with the National Museum of Natural History and made available by the Smithsonian Institution Traveling Exhibition Service. It is funded in part by the Smithsonian Women's Committee. This exhibit was made possible by The Nature Foundation of Will County.
