Arboretum at Arizona State University, Botanical garden at Arizona State University, United States.

The Arboretum at Arizona State University spans the Tempe campus and displays over 300 plant species adapted to desert and varied climatic conditions. The collection features trees, shrubs, and other vegetation from different regions around the world.

The university officially established the grounds as an arboretum in 1990 to support teaching and research activities. This designation of the existing campus greenery created a structured space for scientific work with plants.

The trees stand along campus walkways and open areas rather than in a walled garden, so the collection is part of daily student routes. It belongs to the North American Plant Collections Consortium, and its holdings are grouped into conifers, deciduous trees, evergreens, fruit trees and palms.

The exhibits are not gathered in one walled garden: they line walkways and open areas across the Tempe campus, so plan a route between buildings rather than a single stop. Campus public areas stay open to city streets, so the plantings can be seen daily at no charge.

The date palm and conifer holdings are described in the sources as among the best in the desert Southwest. The trees stand in small exhibit sites along campus walkways and open areas rather than in a separate walled garden, so the collection is passed through on ordinary routes between buildings.
