This picture shows the bark of the David Maple, (Acer davidii). This specie of maple probably has other fine traits, but the one that stands out is the spectacular pattern, texture, and color of the bark. The David Maple is widely considered to be the most attractive of the stribebark or snakebark maples. The leaves of this tree don't have the expected maple leaf shape; they are ovoid with a pointed tip, as you can see from the leaf shadows above.
The name comes from a Jesuit priest, Jean Pierre Armand David, who discovered the tree in central China in 1869. It is known in Britain and Canada as Pere David's Maple. It is a relatively easy tree to cultivate in the garden. It's tolerant of a variety of soils and it is hardy to zone 5. The David Maple is a medium-sized tree that grows to 30 to 50 feet high, making it easier to fit into the landscaping than other maples.
This photo was taken at the Hoyt Arboretum in which is located in the West Hills above Portland, Oregon. There is a nice visitor center at the headquarters on SW Fairview Blvd, with a roomy parking lot and public restrooms that are open in the evening after the visitor center is closed.
A five or ten minute drive from downtown, Hoyt Arboretum is a great place for a hike on the way home from work. The Arboretum is absolutely laced with trails so that visitors can see a maximum number of trees. It's a reasonably short hike down to the Oregon Zoo, the World Forestry Center, and the very fine Oregon Vietnam Veterans Memorial.
