Big Leaf Maple

Mike Vouri

Big leaf maple
(Acer macrophyllum)

This tree has the largest leaf in Washington at 6 to 10 inches long, and is divided into 5 prominent lobes. Look for the specimen nearest the formal garden at English Camp. At 330 years old, it was once proclaimed as the "World's largest Bigleaf maple." Two branches, which broke in the 1970s, reduced the claim as the largest, but it may still be the oldest. The Bigleaf maple next to the barracks, actually a cluster of several trees that have grown together over the centuries, is an island favorite. Please resist climbing its branches, as this will wear down the bark and shorten its life.
