Bigleaf maple. It's got big leaves, who'd have guessed?

Acer macrophyllum or bigleaf maple is a large maple tree native to North America. The name bigleaf maple is well deserved as it has the largest leaves of any maple. The leaves have five lobes with deep wide teeth. It grows long hanging pendants of small green coloured flowers. When grown in a humid climate moss and ferns will grow on the bark of this tree. It's a massive tree so it's not suitable for most gardens. It likes moist soils so it's sometimes found by the side of a stream or river. The wood of this species is used for making furniture and musical instruments, usually as a veneer. The sweet sap is edible and can be made into maple syrup. Deer and horses love to graze on the young saplings of this species.
