Gambel Oak (Gambelii)

The Gambel Oak (Gambelii) is generally described as a perennial tree or shrub. This is native to the U.S. (United States) has its most active growth period in the spring and summer . The greatest bloom is usually observed in the mid spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Gambel Oak (Gambelii) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Gambel Oak (Gambelii) will reach up to 40 feet high, with a maximum height at 20 years of 15 feet.

The Gambel Oak (Gambelii) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a moderate ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -43°F. has low tolerance to drought and restricted water conditions.
