The Hoyt Arboretum, founded in 1922, is located in Portland's west hills. In 1922,  Multnomah County deeded land to the city of Portland to establish Hoyt Park. It was established as Hoyt Arboretum on April 22. John W. Duncan was asked to design a plan for the arboretum. In 1930, he completed that plan and provided specific locations for nearly 40 plant families of conifers and flowering trees. He envisioned more than 500 species.

It is named after former County commissioner Ralph Warren Hoyt. Some clearing had to take place first, but by 1944 all 40 plant families in Duncan's plan were there. Planting slowed following World War II and has continued ever since. Many plants were damaged during the Columbus Day storm of 1962 and some areas had to be completely cleared again.

There's a visitor's center, tours, walks, special events, children's activities, a library and outdoor classroom and many other educational opportunities. It is also home to a Vietnam Veterans Memorial that was added in the 1980s. There is a database of all the arboretum's plants available to the public.
