YELLOWSTONE ARBORETUM
" Stewards of the Natural Environment "
Billings, Montana @ ZooMontana
Visit the Trees !
With almost 200 species of trees, woody shrubs and vines the Yellowstone Arboretum offers an intimate view of trees from many parts of the world. Starting in the early 1990's the arboretum has prided itself on introducing a multitude of native and non-native specimens that adapted themselves to the sometimes harsh Montana climate. At least one specimen of each species is signed for easy identification and all areas are connected by ZooMontana's comfortable pathway system. Here's a few walkable areas that are waiting for discovery. Click here for a close-up view of many more !

The Plaza


The Plaza offers visitors an expansive view of some of the arboretum's Maple, Oak and Locust collections. Seasonal tree colors can best be viewed here as you enter the grounds. The area is used for community events and celebrations throughout the year and is a great place to let the kids run free.
Homestead Collection



Springtime color abounds at the Homestead as the trees burst into life after a sometimes long Montana winter. Highlights of the Homestead Collection include a Hawthorne Collection, Northern Catalpas, Eastern Redbud, Lilacs and the Orchard with newly planted Hazelnuts, Walnuts, Chinese Chestnuts and Cherry Trees.
