Oak Park Conservatory, 615 Garfield St., features three environments filled with botanical specimens. In the Mediterranean Room native plants are displayed; live birds are on display and exotic plants surround a lagoon with a waterfall in the Tropic Room; and the Desert Room blazes with cactus blooms in season. Herbs, perennials and rare native flowers thrive in the outdoor gardens. A fountain also is on the grounds. The Elsie Jacobsen Discovery Garden, a children's interactive play area and water feature, is available seasonally.
