The University of Arizona holds a truly unique collection of plants from arid and semi-arid climates around the world. Many campus trees are the largest specimens in Arizona and have been designated as Great Trees of Arizona. There are 5 trees on the National Register of Big Trees. The UA Heritage Trees are stately links to the University's past. Several are unique to the entire Southwest; a few were the first of their kinds to be planted in the Western Hemisphere.
In September, 2002, the UA Campus Arboretum was officially dedicated and accepted as a member of the American Association of Botanical Gardens and Arboreta. In 2005, the Taylor Family Botanical Plaza was formally dedicated in front of the newly refurbished Herring Hall.
We invite you to explore the UA Campus Arboretum - virtually or actually. See the Plant Walks and Wildlife Maps. Each season we show you What's In Bloom. The campus is open 7 days a week, absolutely free. Many trees are labeled, and more signs are being made.
