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.
