The July issue of the digital magazine, Garden Time, featured an article about the garden.
Here is an excerpt from the article:
The Elk Rock Garden at Bishop’s Close is a treasure of a botanical garden tucked into a Dunthorpe neighborhood overlooking the Willamette River. Originally the home of Peter Kerr, a native of Scotland, the state, along with an endowment for maintenance and upkeep was donated after his death by his daughters in 1957 to the Episcopal Bishop of Oregon on the condition that the garden be open to visitors. Because of this generous gift, we have the pleasure of visiting this gem of a garden year-round.
