HOYT ARBORETUMPortland, OR USDA Hardiness Zone 7b

Hoyt Arboretum is a 90 year old municipal arboretum situated in Washington Park, Portland Oregon. The 200 acre arboretum displays a global tree collection of over 2000 species.

The Ilex collection was designed and established with nursery partnerships in 1997. Large tree donations came from Oregon State University’s nursery breeding program and Teufel Nursery Holly Farm foliage production facility located a few miles from the Arboretum.

The Ilex collection has cultivar and botanical specimen components. It is one of a few public gardens on the West Coast with an extensive Holly collection. We strive to provide gardeners with good alternative holly to grow instead of Ilex aquifolium as the species and some of the cultivars are weedy in Pacific Northwest forests.

We have 212 and 126 taxa in our collection.Martin Nicholson, [email protected] 4000 SW Fairveiw Blvd, Portland, OR
