Texas Arboretum

The Wildflower Center’s newest feature is The Mollie Steves Zachry Texas Arboretum. Developed as a classic arboretum, this is an interpreted collection where visitors can learn about the diversity of Texas trees in a relatively compact area. The ground plane is maintained in simple sweeps of native grasses and wildflowers, and pathways connect different groupings of trees. A major emphasis will be placed on Texas oaks, but many other woody species are included. The arboretum serves as a resource for tree-identification, field trips, and outdoor classes, and is the centerpiece of the Wildflower Center’s tree-related educational programs and events.Plan for Mollie Steves Zachry Texas Arboretum at the Lady Bird Johnson Wildflower Center

Oak Wilt

What Happened Here? Oak wilt devastates central Texas.

Oak Wilt

These trees were killed by oak wilt, one of the most destructive tree diseases in the United States. Oak wilt is caused by the fungus Ceratocystis fagacearum, which disables the water-conducting system of oak trees, causing the trees to wilt and die.
