The Myriad Botanical Garden is a green oasis that offers space and serenity within the concrete urban sprawl of Oklahoma City's downtown. The gardens are spread across 17 acres (6.9 hectares), and the horticulturists often offer educational classes and workshops as well as just a place to relax. Upon entering, the Crystal Bridge Tropical Conservatory contains more than 2000 species of plants and in addition to permanent species, the gardens display rotating exhibits such as orchids and more exotic plants throughout the year. The Grand Event Lawn in the outer gardens and the Water Stage on the lake are frequently used for events like concerts, theater and movie screenings year-round. To enter the Crystal Bridge Conservatory, there is an admission fee.
