Opened in 1859, the Missouri Botanical Garden is tops. The incredible horticultural displays include an English Woodland Garden, a 14-acre Japanese garden, a fantastic home gardening demonstration garden, and specific gardens dedicated to roses, day lilies, irises, dwarf conifers, boxwood, or bulbs. Step into the rainforest inside the fabulous Climatron, the first geodesic dome specifically for conservation. Enjoy your walk through any or all of these, or rest your feet on a narrated, accessible tram tour through the grounds. There are several places to eat within the grounds, and allow yourself time to explore the Garden Gate Shop before you leave.
