Completed in 1997, the $800,000 National Wildflower Research Center founded by Lady Bird Johnson is a 279 acre environmental education facility located in the picturesque Texas Hill Country. The complex consists of 10 buildings and 15 acres of gardens and wildflower restoration areas. Early site planning efforts located the complex and roadway system with respect to the existing watershed. The office of J. Robert Anderson oversaw the environmental protection program, which included tree protection, erosion control, and reuse of site stone and native soil. The garden design approach reflects the regional landscape by re-creating habitat areas which are common to the hill country. The theme gardens include four water features, dry woodlands, trails, rocky ledges, and wildflower meadows as well as demonstration gardens.
