Since 1983, Friends of the Delbert Hunter Arboretum and Botanic Garden, a non-profit group an organization, has planned and developed a recreational and educational resource with the Dallas city park.

Here is a unique opportunity to see a living museum of Native plants. The varied terrain of the Arboretum provides ecological niches suited to perennials, conifers, oaks, wetland species and dryland desert plants.

Recently added is a rock garden of native Lewisia plants honoring Viola Sobolik, the first curator. Go to the extreme south end of the park to see this site. The Arboretum is open year round. Tours are self guided. Identification and interpretive signs enable visitors to appreciate the variety of Oregon trees, shrubs, and flowers. Many of these specimens are seldom found so accessible.
