The Quercus macrocarpa var. x gambellii, also known as Bur-gambell Oak or Burgambell Oak, is a hybrid of the Bur Oak and Gambel Oak species. Known for its fast growth and heavy production of acorns at a young age, this hardy oak exhibits remarkable drought and cold tolerance. At maturity, it can reach up to 30 meters tall and 3 meters in trunk diameter, making it one of the largest and longest-living white oaks. Wildlife such as squirrels, chipmunks, deer, birds, and turkeys benefit from its acorns. The Burgambell Oak is also tolerant to urban conditions and is a popular choice for gardens, parks, and street trees. This impressive oak can be found throughout North America and grows in hardiness zone 3.
