Bring the whole family out to enjoy the Chicago Botanic Gardens inside and out. The Gardens tops off their month-long orchid show with this last weekend of orchid displays and sales hosted by the Illinois Orchid Society. Feast your senses on a stunning variety of shapes, sizes, colors, and smells, and then treat yourself to an orchid treasure to take home. More details can be found at this website.
