Quercus macrocarpa is a deciduous tree, known for its large acorns and deeply lobed leaves.
The leaves are large, typically around 20cms long and the shape is deeply lobed, with each leaf having 5 to 9 rounded lobes, which are often irregularly toothed along the margins.
The upper surface of the leaves is dark green and glossy, while the underside is lighter in color and may have a slight fuzziness or hairiness
The gray to brown bark is rough and deeply furrowed, forming ridges and fissures that give the tree a rugged appearance.
The acorns are typically about 4cms long and have a thick cap that covers about one-third to one-half of the nut. The cap is fringed with distinctive moss-like or warty projections, giving rise to the common name "mossycup oak."
The branches of Bur Oaks are stout and often have a spreading, open growth habit. The tree forms a broad, rounded crown with age, making it an imposing specimen in the landscape.
Overall, Quercus macrocarpa is a majestic tree with a commanding physical presence that make it a valuable addition to large domestic gardens, parks, and naturalized landscapes.
