Enjoy a brisk winter walk and see the ever-changing beauty of the landscapes at the Chicago Botanic Garden. Falling snow brings a serene beauty as it turns vistas into picture-postcard scenes. Evergreens, ornamental grasses, berries and bark can provide interest even on dull, cloudy days. Red-twig dogwood, birches and yellow willow branches really stand out at this time of year. Take a walk along the east road or around the Great Basin for ever-changing views of the ice-covered lakes and bridges. When you need to warm up, take a quick trip to the tropics in the Greenhouses. Aloes and acacias in flower are the stars, until the Orchid Show begins next month. Children and adults alike will be delighted by finding the cocoa tree, bananas, succulents both beautiful and bizarre, prickly cactus and beautiful orchids.
