The Yellowstone Arboretum contains a unique collection of trees, woody shrubs and vines not normally found in Montana. The first trees were planted in1992 with the expansion of the ZooMontana grounds and since have been expanded and nurtured for future generations. The arboretum staff has made a serious re-dedication to fulfilling the original obligations of the zoo by expanding even further the variety of trees for visitors enjoyment and education.


Our inventory page lists all of the current accessioned specimens. All are linked to their own special data page where you can view photos of the trees and bark. Also included is growth records and pertinent data describing the tree, location and tree benefits. You can also use the search bar located below in the footer to search for a particular species or individual tree.

The Yellowstone Arboretum tree gardens are connected by an extensive pathway system and consists of a number of individual gardens all with their unique personality and design. The Millennium Grove is one of those areas where a collection of 52 Black Hills Spruce trees form a meditation circle planted in honor of the year 2000 celebrations. Also on the list to visit is the Remembrance Circle located near Dottie's Garden and the Waterways Collection. All these areas can be found on our map page
