Friends of Terwilliger have been working with Portland Parks and Recreation (PP&R) for the past five years to restore a narrow strip (~120ft wide) of ~1 acre parkland centered around the Bancroft St right-of-way just below Terwilliger Parkway and the Marquam Hill hospitals.
A long-term project to establish a native plant demonstration garden, based upon Frederick Walpole’s illustrations of Oregon Native Plants, is about to begin in Historic Terwilliger Parkway on either side of the SW Bancroft St right-of-way.
It is this beautiful woodland native plant, Oregon Grape, Mahonia aquifolium, that can be found growing along Terwilliger Parkway and throughout most of the city. Oregon designated the Oregon grape blossom as the official state flower in 1899. The following description of this remarkable plant has been adapted from the Portland Nursery website (http://portlandnursery.com/plants/natives/mahonia.shtml).
