More than 900,000 visitors from over 70 countries came through our gates in 2012. The Arboretum was listed among the top three arboretums in the nation in Southwest Spirit Magazine, offering the public a complement of dedicated gardens, an array of popular annual events, educational programs for children and adults, and an emphasis on family-oriented activities. Ground-breaking horticultural research conducted in our Trial Gardens continues to contribute to an important body of knowledge, both regionally and nationally. The Arboretum’s 66 acres on White Rock Lake provide a complete life science laboratory with endless potential for discovery. The Arboretum has a 65-member Board of Directors, 75 full-time paid staff members, 32 part-time paid staff members, and more than 400 year-round volunteers.
