Did you know that Hoyt Arboretum houses a collection of more than 8,000 trees and plants representing over 1,000 species and more than 600 cultivars from around the world? This collection is very accessible to scientists, students and others involved in research and study since Hoyt Arboretum is located just 2 miles west of downtown Portland and can be reached easily by car, bus or light rail.

The Arboretum’s collections are planted in taxonomic families in accordance with a master plan and are grown from seeds collected in the wild.  Specimens within each collection are labeled so that visitors can find individual trees using the Plant Inventory Guide available at the Visitor Center.

A library of over 500 horticultural books and periodicals in the Bill deWeese classroom is open to the public during Visitor Center hours.
