The Arboretum serves as a laboratory and workshop for students in the Landscape Horticulture program. Here students apply what they've learned in the classroom, including:
  • Pruning
  • Landscape maintenance
  • Installation / maintenance of irrigation systems
  • Landscape construction
  • Garden renovation
  • Propagation
  • Integrated pest management
The Arboretum is also a classroom for local gardeners. Continuing Education classes are held here. Plus, gardeners can see mature specimens of trees and shrubs and imagine the possibilities for their own landscapes. 

Most of the 300 plants on the Washington State Nursery and Landscape Association's CPH exam are found in the Arboretum at South.

The Coenosium Rock Garden, now an American Conifer Society Reference Garden, was built over 6 years, beginning in 1999, by students in the Landscape Construction Class.
Some students signed up for the class multiple times, though they could get credit for it only once, because they wanted to see the project through to completion.
