Trees and Shrubs

Large London sycamores line the park's parking area.
Trees, such as these London sycamores that line the park's parking area, provide much appreciated shade during the hot, dry summer months.



Whitman Mission National Historic Site is located in what was once an extensive grassland. Except for in the mountains, trees would have been relatively few and found mostly next to streams and rivers. When the Whitmans came they wanted trees. Dr. Whitman wrote to friends back east asking for locust, chestnut, and walnut seeds. Narcissa obtained sprouts of apple and peach trees from Fort Vancouver. Today the trees the Whitmans planted are long gone. But people still love trees. Landscapers planted many trees and shrubs on the park grounds to add beauty and provide shade. An apple orchard was created to represent the one planted by Dr. Whitman.
