Small, quiet. Elk Rock Garden of the Bishop's Close is delightful private garden of a Scottish family (Kerr's) on a steep hill by Willamette River. The children gave the estate and an endowment for its maintenance to the Episcopal Bishop of Oregon on condition that the garden be open to visitors. Hence, the name. There's a wide variety of plants, which I need to come here again with a botanist.
The house was closed, so was the visitor center, on this Sunday afternoon. Door was open. The neighborhood seems quite affluent.
