Bur Oak (Quercus macrocarpa)

Bur Oak (Quercus macrocarpa) is a large, long-lived native shade tree valued for its strength, adaptability, and impressive stature in Prairie landscapes. Known for its deeply lobed green leaves and massive acorns with fringed caps, this oak provides year-round interest while supporting wildlife and native ecosystems.

This slow-growing but highly durable tree develops a broad, rounded canopy that offers excellent shade once mature. In fall, the foliage turns attractive shades of yellow-brown, adding seasonal colour to the landscape. Bur Oak is especially valued for its ability to tolerate drought, wind, urban pollution, and difficult soil conditions, making it one of the best large shade trees for Alberta and other Prairie regions.

In Alberta, Bur Oak performs best in full sun with well-drained soil, though it adapts to clay, sandy, and alkaline soils once established. Its deep root system contributes to drought tolerance and long-term resilience. This tree is ideal for parks, acreage properties, shelterbelts, and large residential landscapes where long-term structure and shade are desired.
