Zilker Botanical Garden is located on 26 fenced acres of varied topography on the south bank of the Colorado River near downtown Austin. Its diverse topography is especially suited to depicting different habitats and displaying an array of native, hybrid and exotic plants. The Garden is the centerpiece of Zilker Park and the Lady Bird Johnson Lake (Colorado River) corridor and is its most extensively used facility. Special events can take place on Zilker Botanical Garden grounds or in the building, including weddings or memorial ceremonies. The Garden Center Greene Room and Auditorium are available for receptions, parties and gatherings.
