Bur Oak is a rugged tree with thick spreading branches and an irregular rounded crown. It prefers moist locations, but tolerates poor, dry soil in fields, along roadsides, and even in the prairie.
Bur Oak has a top-heavy leaf, broad toward the tip and abruptly narrowed toward the center. The indentation or sinus sometimes cuts close to the midrib. The lower lobes are shallow, and the tapering leafbase is wedgeshaped. The scaly, hairy, deep cup of its large acorn gives this Oak its name. The cup covers abouthalf the net. The deeply furrowed bark is grayish-brown.
