Bur Oak (Quercus macrocarpa)
The bur oak’s large leaves are 15 to 25 centimetres long, and are shiny green on top, and pale and hairy underneath. Its acorns, which are 1.5 to 3 centimetres long, have a deep cup covering 2/3 of the acorn. This cup has a bristle fringe around the upper edge. Depending on where it grows, the bur oak can be different shapes. It’s usually tall with a straight trunk but if grown in shallow soil, it can be smaller with a twisted trunk and gnarled branches.
