Zahn Rock Garden

The Earline and Doug Zahn Rock Garden serves as a focal point on Wildwood’s Butler Hill. California Poppies, Native Butterfly Weeds and Texas Bush Sage are just a few of the 56 varieties of Waterwise and Xeriscape plants embedded in the elevated slate and boulders. Looking south, the rock garden’s looks out across the Arboretum and onto Swan Lake.
