Bigleaf Maple

Acer macrophyllum

True to its name, bigleaf maple carries the largest leaves of any maple in the world — broad, five-lobed, and often draped in a thick coat of moss and licorice fern in the region's wet climate. Coast peoples dried and ground its inner bark as a soup thickener and wove fiber from it into rope and baskets.

Where found

Moist lowland forests, riparian corridors, and urban canopy throughout western Oregon and Washington.

Fun facts

  • Its winged seeds (samaras) spin like helicopters on the way down.
  • A single tree can host an entire hanging garden of epiphytes.
  • Sap can be tapped for syrup, much like eastern sugar maple.
