(Blue Oak, Mossycup Oak)
This oak is not as graceful as his brothers. Its stout trunk flings crooked branches in all directions. It produces the largest leaves that can be ten inches long. They are shaped like a bass fiddle, and they do not hang on the tree all winter like leaves of other oaks. The large acorns which can be two inches across are half encased by a heavily fringed cap. They mature in one year. Although more coarse and irregular than the other oaks, the bur oaks makes a nice shade tree and with others can form a good shelterbelt.
