Bur Oak


Hardiest oak for the Grande Prairie area. Broad spreading, rounded crown. Slow growing (but fast for an oak) with unique acorns and majestic, thick lobed leaves, with yellow fall color. Great for standalone piece, gardens, parks, walkways etc. Deep ridged bark. Is very tolerant of urban conditions. Is one of the most massive oaks, with a trunk diameter of up to 10 ft (3 m) at maturity. Native to North America in the eastern and central USA, and eastern and central Canada. Sometimes called Burr Oak, Mossycup Oak, Mossycup White Oak. Sometimes confused with overcup oak and white oak, both of which it occasionally hybridizes with. The acorns are the largest of any North American oak, but heavy nut crops are borne only every few years, known as masting. Likes to grow in the open, away from other canopies. Drought resistant once established, possibly due to its long central taproot. Specific epithet comes from the Greek words macro meaning large and carpa meaning fruit in reference to the large acorn size. Tolerates a range of moisture regimes.
